With Manufacturer's Scan Tool

General
The on-board diagnostic (OBD) system for the SRS continually diagnoses the function of SRS system components and stores any diagnostic trouble codes (DTCs). The principle behind VADIS/VIDA information presentation is the same as for other on-board diagnostic (OBD) systems.

Fault Indication
The driver is warned via the combined instrument panel if any fault occurs in the SRS system.

A VADIS/VIDA station must be connected to the car data link connector (DLC) in order for a fault source to be identified.


Diagnostic Trouble Codes (DTCs)
The control module will store a diagnostic trouble code (DTC) if it detects a fault. The control module can store up to 10 diagnostic trouble codes (DTCs).

If a fault disappears for any reason after the diagnostic trouble code (DTC) has been permanently stored in the control module, information about the fault remains in the control module.

Reading And Erasing Diagnostic Trouble Codes (DTCs)
Stored diagnostic trouble codes (DTCs) can be read off and erased using this function.

After the diagnostic trouble code (DTC) is stored the function can also read off if the fault is still present (permanent fault), or if the fault has disappeared for any reason (intermittent fault).

Diagnostic trouble codes (DTCs) can only be erased when all diagnostic trouble codes (DTCs) have been read at least once.
