GMLAN SYSTEM

  The broad application of the system GMLAN new models of Chevrolet, laying the groundwork for the launch of a new technological era, completely changed the traditional traditional philosophy to date electronic systems.
The variety of new electronic systems, is applied to the high demands that are using using integrated software, communications and data transfer.

Basically it is an advanced system possible - Bus which is indicated for use in  vehicles fitted fitted with high-tech systems (ESP, AWD, TCM, etc.).

The current exchange of information between electronic control units are made different by using separate cables. The disadvantage in this case back to the fact that due to the the increased amount of information needed to be, increasing the number of wires, thus increasing the electrical potential damage.The highly innovative features of the system to transfer data GMLAN day. The data can be simulated with a wagon. In the same way that a car carrying a large number of people in in these destinations, so the data transfer is handled a large number of units of information between different electronic control (exchange data). The data exchange between between electronic control unit allows the unit acts as a single operating system. The more information get an electronic control system, the more fully implement the functionality of its its own independence.

The advantages of using the data transmission system - the data bus is:At the sensor and signal cables from the use of signals from sensors.Less cabling across the entire wiring system.A significant reduction in weight of the wiring from avoiding the large number of cables.Less power connections - connections at both ends of the electronic control unit.Improved reliability and episkefasimotita.The ability to use the new function facilities.The network GMLAN (GM Local Area Network) is a type of data can be - used bus and passed only by GM, Chevrolet model applies.Evolutionary history of the system can - Bus. About Bosch collaboration with Intel, to develop protocols can - Buses in 1987 specifically for the needs of the automotive industry. The original CAN - Control Area Network, please refer to the electronic control units are interconnected to exchange data. The protocol can be - is recognized worldwide in the automotive bus, a standard system of data exchange, while being used in industrial automation. This is mainly due to the structure of the network settings and software data protocols are used. It also provides high reliability for engineering costs are relatively low.       This system ensures the exchange of data on the car, and have replaced other systems such as pulse width modulation - PWM, analog current, trend lines, etc.Regional data GMLAN. The unique elements associated with GMLAN system is the electronic control unit. Other components such as actuators, sensors, lights, electric motors are connected to the electronic control unit using regular cable. GMLAN system used by Chevrolet, is a serial transmission systems and data exchange.This exchange can take place through - in the form of bus voltage pulse with a specified range and latitude. The electronic control unit that functions as receiver, which actually means that it can emit or receive information.Their activities can be identified with a conversation over the phone. In conversation, people use communications voice.         In the communication system can - bus, electronic control units using the corresponding voltage signal. The electronic control module shows information of the network and other entities to - listen. Some may use the information, while others will be ignored.The "auditors" and can "broadcast" may, be placed inside each electronic control unit. The Bus line, which can bring both ends of the resistor terminals. The resistor is to prevent data back after reaching the destination. This way to prevent possible interference with other data circulating on the Internet. The terminal resistor can be found embedded in the electronic control unit or the wiring inside as separate components.

GENERAL INFORMATION:GMLAN is a set of high level protocols for diagnosing ECU systems on supported vehicles. There are more than 20 different commands for reading,writing, and clearing information inside an ECU. GMLAN is a combination of GM2190 and Keyword 2000 diagnostics. All functions are defined in GMW 3110. GMLAN uses functions from ISO15765-2 (USDT Messaging) and supports OBD CAN, legislated by J1979 Requirement.

GMLAN has been extended with additional requirements and is often referred to as GM Global A. Global A includes many types of networks and protocols. Intrepid offers the most complete functionality for GM Global A.GMLAN FEATURES IN VEHICLE SPY .All the GMLAN features in Vehicle Spy are too numerous to list; however, here are a few to consider:

GMLAN Snapshot :The GMLAN Snapshot reduces all common diagnostics into one or two click operations. GMLAN Snapshot will query all ECUs on an entire vehicle and report all DTCs, DIDs, and other information in a quick list.Innovative Diagnostics SupportIntrepid's diagnostic solution exceeds other solutions by organizing diagnostics into Jobs. These Jobs can be saved and scripted. The data from these Jobs can be logged, plotted or used for trigger expressions. Unlike other tools, the GM engineer never needs to go offline for setup.GMLAN Virtual Networks View :The GMLAN protocol has a network management system called virtual networks. This concept is difficult to master and debug. Intrepid provides a virtual network view to visualize this complex aspect of GMLAN.GMLAN Simulator :The GMLAN Simulator simulates any combination of ECUs on the bus. The user can specify the signal data for each message. This data can include waveforms or data calculated from other signals or data values. Also, the simulator is fully scriptable.DPS Tools Flash Programming : Intrepid has developed full support for ECU programming using GM's DPS tools programming. GM engineers can select neoVI as an option and program on high or low speed CAN. Often Intrepid's hardware is faster – sometimes up to 50% when compared to other hardware tools.

SILVERADO

THE TRUE MEANING OF HEAVY-DUTY

Dynamic Duo: Duramax^® 6.6L V8 Turbo-Diesel and Allison Transmission^®

Our available Duramax^® Diesel has impressive torque, horsepower and towing numbers. With a 36-gallon tank, the Duramax offers up to approximately 680 highway miles^†.

The heavy-duty Allison^® 6-speed transmission harnesses the power of the available Duramax. To make sure it can handle the immense amounts of torque, we've given it a strong torque converter, a larger diameter output shaft and more robust clutches.

3500HD Brings Maximum Towing and Payload from Silverado

The Regular Cab Silverado 3500HD with a diesel engine can tow up to 23,100 lbs. with a fifth-wheel hitch^†, while the Extended and Crew Cabs with diesel engines can tow up to 18,000 lbs. with a conventional hitch^†. Our Regular Cab equipped with a gas engine has a maximum payload capacity of 7,222 lbs^†.

Useful for when you’re hauling heavy loads, Trailer Sway Control (Single Rear Wheel Models) senses when a trailer starts to sway and automatically applies the truck’s brakes while reducing engine power. This feature works to let you get your truck back on track if necessary. If you’re stopped on inclines greater than 5%, Hill Start Assist (SRW models) automatically kicks in to keep the truck in place for about a second to give you just enough time to accelerate before the truck can roll backward.

Auto grade braking, which uses transmission downshifts to allow engine compression braking to slow the vehicle and its load, works in and out of Tow/Haul mode on the Vortec^® 6.0L engine.

• 4x4 6,000-lb. Front Gross Axle Weight Rating (FGAWR).

  The front suspension contains huge precision-forged upper control arms and torsion bars along with the largest steering gear we've ever used on a heavy-duty pickup truck, which supports up to a 6,000-lb. front gross axle rating. So every HD 4x4 model including our powerful Duramax^® Diesel can accommodate a snow plow with the available Snow Plow Prep Package. Silverado HD incorporates torsion bars that allow an owner to adjust the front of the vehicle back to its normal ride height, even with the weight of a plow attached.

  

  
  

  Powerful Support

  Our chassis features a high-strength, fully boxed steel frame that allows Silverado 3500HD to shoulder up to 7,222 lbs. of payload^††. The suspension has massive components to handle huge loads and still provide a quality ride.

  The independent front suspension allows each front wheel to react independently to rough terrain. The steering knuckle is tall and heavy to better manage larger capacities. Precision-machined forged upper control arms support the truck’s strength. These front suspension components help to keep each wheel in a vertical position and more firmly planted on the road.

  The rear suspension has 3-inch leaf springs with an asymmetric design that helps handle increased payloads. The staggered rear shocks are designed to help dampen the vertical movement of the truck. These rear suspension components both help to reduce wheel hop on acceleration.

2013 Colorado

Chevrolet has unveiled its all-new 2013 Colorado, and when the company calls it a global product, it's not just referring to where the truck will be sold. Its development spanned five continents, but the bulk of the work was done in Thailand-where the truck was introduced-by Brazilian engineers, and GM's South American Design Center penned the shape. GM first showed a concept of the truck in Thailand (If you are wondering, "why Thailand?" it's because compact trucks are very popular there), following that a few months later with another concept in Argentina, but the big question is whether or not "global" includes the U.S., GM isn't saying, but the Colorado seems well-equipped to do battle here in the States.

Smooth Operator

The new Colorado looks like a strong replacement forour truck based on appearance alone. Its shape is modern and tough, with smooth, Malibu-like headlights; a large dual-slot Chevrolet grille; and muscular, swollen fenders. Chevy will offer 26 different trim, body, powertrain, and ride-height combinations, a level of choice similar to what you find in the full-size-truck market here.

The body-on-frame Colorado is available with regular, extended, and crew cabs; two body widths; two- or four-wheel drive; and-independent of the number of driven wheels-a high or low ride height. Buyers can choose from three trim levels that follow the same progression as U.S.-market Chevys: LS, LT, and LTZ. Stability control, anti-lock brakes, traction control, and front airbags are among the Colorado's standard safety features. The interior boasts chrome accents and a classy dual-cowl dash with square Camaro-like gauge pods and ice-blue LED backlighting. Vinyl, cloth, and leather seats are available, and all Thai Colorados have standard auxiliary audio and USB inputs.



In addition to the numerous build combinations available, the Colorado offers two new diesel four-cylinders. Just like the truck they will power, the engines are labeled as "all-new" by GM and are a part of a new global line of diesel four-cylinders. The base is a 2.5-liter unit that makes 150 hp and 258 lb-ft of torque; the second is a 2.8-liter that makes 180 hp and a meaty 346 lb-ft of torque when bolted to a six-speed automatic transmission, 324 lb-ft when mated to a five-speed manual. If the Colorado does make it here, it likely will feature a gas-only engine lineup. Chevy recently announced that a diesel-powered Cruze is on its way here for 2013, though, so don't rule out the possibility of an oil-burning small pickup for the U.S. somewhere down the road.

"Don't rule it out" seems to be the line regarding the new Colorado's chances in the U.S. Chevrolet developed the truck for more than 60 markets spanning the globe; it's hard to believe the U.S. would be left out of that count. Depending on how you look at it, the death of the Ford Ranger is either an indication of where the small-truck market is going or an opportunity for GM to seize the segment.

The UAW recently disclosed some of its tentative contract agreements with GM, revealing that the Shreveport, Louisiana, plant that currently produces the American-market Colorado and GMC Canyon is set to shut down by June 2012. However, the company also said it will invest $380 million in its Wentzville, Missouri, plant and add a mid-size pickup program there, so the Colorado will continue to be sold here-Chevy just won't say whether it will be this one, some other new one, or the same old truck. We think it'll be this one

Chevrolet Colorado Show Truck in Thailand

Chevrolet Debuts Colorado Show Truck in Thailand, Plans for U.S. Sales Still Unclear

Chevrolet has photographically unveiled its Colorado pickup concept, following a teaser image a few weeks ago. The truck will take the stand at the upcoming Bangkok auto show. A production version of the truck goes on sale this fall in Thailand, but the big question is whether this concept previews a vehicle that will come to the U.S. to replace our aged and never-so-great Colorado.

In contrast to the current Colorado, which has boxy styling evocative of the last-generation Silverado, the concept truck features a smoother body that is much more in keeping with current Chevy design. The corporate front grille and headlights are toughened-up Malibu fare.

The running gear is fairly standard: a 2.8-liter diesel provides the power to two or four wheels—though if this truck does ever land in the U.S., you can bet on it switching to gas power. Still, it’s just about guaranteed to be friendlier on fuel than the current Colorado’s lineup of four-,five-, and eight-cylinder engines.

Many of the Colorado’s interior fittings echo recent Chevrolet offerings, with a Cruze-style steering wheel, square-ish gauges reminiscent of those in the Camaro and Traverse, and a dual-cowl dash design. All of those have a good likelihood of making it through to production. It’s a good bet, however, that the large-screened infotainment system, LED exterior lighting, and funky 20-inch wheels will remain on the show stand.

Chevy previously told us that the new Colorado would be a global design, implying that it could meet U.S. regulations, but wouldn't confirm whether it is, in fact, headed to our shores. Full-size trucks like Chevy’s Silverado dominate the U.S. market, but elsewhere, smaller pickups prevail. With fuel prices in the States headed north, however, we could see a renewed interest in Colorado-sized trucks—so long as they can deliver real savings at the pump.

Colorado Pickup Concept

At the Buenos Aires auto show this week, Chevrolet is showing another concept of its next-generation Colorado pickup, this time in jacked-up, left-hand-drive, double-cab “Rally” form. When we last saw the truck three months ago—halfway around the world in Thailand—it was as the sleek, right-hand-drive, extended-cab Colorado concept. This latest take is a real feast for the eyes, with fat fenders, front and rear winches, and more ancillary lights than an ambulance. The production version certainly will be toned down, but from what we can tell from looking at both trucks, the next Colorado is going to look pretty cool.



We're still unclear on whether we will see the truck in North America. Chevy PR isn't much help, hemming and hawing when asked if we’ll get it, saying words to the effect of “well, it’s a global truck,” but little else. While the mid-size truck segment has been slow of late, a U.S. introduction for at least a commercial version of the Colorado is looking more and more likely, given that the same economic forces that have made the Ford Transit Connect viable for the van market also apply to pickup market. Such a truck would have to prove beefy enough to handle professional duties, and would likely have to offer at least one gas-powered V-6 on the order sheet, although the 2.8-liter turbo-diesel supposedly installed in this Rally concept would probably pull as many stumps as any gas-fired six-pot GM could come up with.

“The Rally Colorado Concept is looking to the future of the global Chevrolet pickups,” said GM, in a translated statement. We think that future ought to include GM’s home market.

Corvette Stingray convertible to debut at Geneva

The 2014 Chevrolet Corvette Stingray convertible will make its world debut on March 5 at the Geneva Motor Show.

"It's fitting to introduce the new Stingray convertible on the global stage at Geneva, because Corvette is the face of Chevrolet the world over," said Susan Docherty, president and managing director of Chevrolet and Cadillac Europe. "It is an icon that has long been recognized and admired even in countries where it's never officially been offered."
Currently, there are Corvette owner and enthusiast clubs in more than 100 countries. In fact, 58 percent of the 1.1 million fans who like Corvette's official Facebook page are outside the United States.
The Corvette Stingray convertible will deliver the same balance of technology, design and performance introduced on the coupe earlier in January in Detroit.
"Every Corvette is designed at the outset as an open car," said Tadge Juechter, Corvette chief engineer. "The new Stingray is no different, with the coupe and convertible designed to excel in any situation – be it your daily commute, a drive across the continent, or charging through twisting backroads."

A brand that fires the public imagination

The Chevrolet Motor Car Company achieved a significant milestone on November 3rd 2011; its first 100 years.

Founded all those years ago by Swiss-born Louis Chevrolet and US entrepreneur Billy Durant, the brand is now looking to the next 100 with the same spirit of creativity, optimism and innovation it had right from the day it was founded. Today, Chevrolet is one of the world’s best-known car makers.

Apart from the successes along the way that you’d expect – a heritage of great cars, exciting technology and superb racing credentials – the Chevrolet brand has etched itself much deeper into the public consciousness and is now an established part of popular culture.

In short, Chevrolet is one of those rare brands that have managed to fire the public imagination.

People write songs about Chevys

Literally hundreds of pop songs over the decades feature Chevrolet words in their lyrics and song titles. Artists like Don Mclean, Elton John, Kings of Leon, ZZ Top, The Ramones, The Beach Boys and Snoop Dogg have all included “Chevy” lyrics of one sort or another. And then there are those songs where Chevrolet’s in the song title itself. Just think of Prince’s “Little Red Corvette”.

Chevys star in the movies

Chevrolet cars have played big in roles in a number of blockbuster movies over the years. Unsurprisingly, it’s the Corvette that wins the starring roles in movies like Austin Powers, Corvette Summer and Demolition Man, but it’s the Camaro plays a central role in the massive movie hit Transformers.

Chevys win races

Corvette is a dominating presence in racing, as shown by seven wins at the famed 24 Heures du Mans in France and the many wins clocked up at The American Le Mans Series based at the Sebring International Raceway.

In 2010, 2011 and again in 2012, Chevrolet dominated WTCC (World Touring Car Championships), winning both driver and manufacturer titles in the award-winning Cruze.
