Diagnoza Chevrolet Cruze

[VAXXi]

Se pare ca pe Cruze se foloseste un nou sistem de diagnoza, numit GM Global Diagnostic System (GDS). Am subliniat ce pare mai interesant

With the recent arrivals of the 2010 Camaro, LaCrosse, Equinox, Terrain and SRX in dealerships, technicians have had their first experiences in diagnosing GM Global Architecture (Global A) vehicles using the new GM Global Diagnostic System (GDS). These vehicles do not permit Tech 2Ÿ communication for diagnostic purposes. (Fig. 1) GDS is a PC-based diagnostic application that works with simple menu-driven commands using a standard WindowsŸ interface on a Techline service PC. It takes advantage of the display and processing power of the PC to provide technicians with the ability to work with vehicle data in ways unavailable on the Tech 2. Technicians will be able to view much more data from many different perspectives along with an improved snapshot feature.

 

Several additional Global A vehicles will be introduced shortly that will also use GDS, including the Chevrolet Cruze, Buick Regal, Saab 9-5 and Saab 9-4X. The Multiple Diagnostic Interface (MDI) combined with GDS will be the diagnostic tool used on Global A vehicles, while other vehicles will continue to use the Tech 2, making both scan tools required diagnostic tools in the dealership. TIP: When the Service Information instructs technicians to use a scan tool during diagnostic procedures, it does not reference a specific tool, such as the MDI/GDS or Tech 2. Technicians need to determine the proper scan tool to use based on the vehicle being serviced.

 

 

Global Electrical System

 

The Global A models using GDS are truly globally-designed vehicles. They are built around the world for several different markets. This requires vehicle systems to meet the requirements of varying regulations in different markets, some of which can have an effect on the way vehicles are typically diagnosed and serviced half-way around the world. One recent issue experienced in dealerships may be a no start condition after swapping an ECM or other module from one Global A vehicle to another. The Global A system does not allow controller swaps between vehicles. This includes these modules: ECM, BCM, EBCM, SDM, ECC and IPC. If a module on a Global A vehicle is swapped out, it will result in a no start condition in both vehicles because the module security codes do not match.

 

 

Using GDS

 

In order to be ready to service the new 2010 Global A models, it's recommended that the GDS application be downloaded and installed before Global A vehicles start arriving at the dealership. GDS can be downloaded through TIS2Web by clicking on the GDS icon on the TIS2Web home page. The application must be loaded on each shop PC individually. Once installed, GDS can be launched from the PC desktop icon or from TIS2Web. Also verify your MDI is configured for your dealership's network and updated with the latest version of software. Updated MDI software is automatically downloaded to the PC through either SPS or GDS, but technicians need to update the MDI when prompted with the new software using the MDI Manager software application. In addition, since the MDI is now being used as a diagnostic tool, as well as SPS, it may be beneficial to reassess how many MDIs your service department will require. Additional units can be ordered through 1-800-GM-TOOLS.

 

In order to take full advantage of PC-based vehicle diagnostics, notebook and tablet computers will provide technicians more mobility and efficiency by being able to perform diagnostics on a road test as well as reducing the amount of time spent going back and forth between the vehicle and a desktop PC. If your dealership is looking into purchasing additional computers -- notebooks or desktops -- be sure to review the latest recommended PC specs.

Interesant dar chestia mi se pare mai mult de reclama.

 

Testerul Tech 2 se foloseste dupa cunostinta mea ca unica solutie de diagnostic pentru masini de pina in 1996-1997 si ca alternativa probabil al unele dupa acest an. Testerul foloseste o conecxiune ALDL sau OBD I (nu cunosc Exact)

Duap 1996-1997 Sa introdus testerul OBD II Cernics SCAN-100 (Pentru Daewoo - daca mai tin eu bine minte numele)

Probabil ca in 2010 au decis ca nu se merita bani investiti pe sistmele astea de diagnoza si trecerea la unul Computerizat (Care este mai ieftin), conexinea fiind tot OBDII sau poate alternativ mai noua conexiune CAN pe linga OBDII.

 

Daca folositi un tester OBDII parerea mea este ca puteti diagnostica fara probleme sistemele de baza ale masinii gen ECU Injectie, ABS, Airbag,..

 

Cred ca topicul asta ar fi mai potrivit la probleme tehnice si mai putin la piese schimb.

OBD2 si CAN sunt lucruri diferite, alaturarea lor este pur intamplatoare.

[balogm]

Nu a zis nimeni ca OBDII si CAN este acelas lucru, si nu stiu in ce masura alaturarea lor este pur intimplatoare din punctul tau de vedere.
