Self-Diagnostic System: Notes

WARNING: This page is about a different car, the 1996 Volvo 850. However, it is still accessible from the selected car via links, so may be relevant.

SRS sensor module has on board diagnostic (OBD) system to provide self diagnosis and other information which can be read off using Volvo scan tool connected to the Data Link Connector (DLC). See Figure. When ignition is on, SRS OBD system carries out an initial self test. After self-test is completed, SRS OBD goes into monitoring mode. The system checks for internal faults in all SRS outputs and in output for SRS warning light.

NOTE: If SRS warning light is on, there is a fault in the SRS system.
