Vehicle Identification

Vehicle ID is carried out on the basis of control module data (EWS and IKE/Cluster ZCS)

For automatic ID, the DIS or MoDiC reads the ZCS code to determine what systems are installed in the vehicle and directly seeks them out. This process is much faster than previous method of polling all systems possible for a specific vehicle series.

If the D bus is faulted or the tester can not communicate for whatever reason, Manual ID is required.

When either manual or automatic vehicle identification has been completed, the Vehicle System" screen appears.

First carry out the short test to interrogate the fault memories of all control systems.

The system contacts the control modules directly to check if the control module is installed and capable of communication.

The status of the control module is then displayed in the Vehicle ID screen.

Another option is to check control modules for individual interrogation by pressing the systems individually from the screen.

Correct vehicle identification is the first essential step for both system guided and user guided troubleshooting.
