Diagnostic services
The following diagnostic services are available for the SRS system
- Read diagnostic trouble codes (DTCs)
- Erase diagnostic trouble codes (DTCs) (all DTCs except those stemming from internal faults in the SRS unit can be erased)
- The identity of the SRS system's SRS module and side impact sensors and all installed software can be read off via the VIDA station.
Diagnostic trouble codes (DTCs)
Diagnostic trouble codes (DTCs) are stored by the SRS module's internal diagnostic procedures. The diagnostic trouble codes (DTCs) are defined in the software which is installed in the factory. Diagnostic trouble codes (DTCs) are stored in the event of each diagnosis case automatically carried out by the SRS module or activated by the VIDA station.
