The symptom chart can be used to help locate supplemental restraint system (SRS) concerns if no DTCs are retrieved and the listed symptoms are observed. Whether or not the listed symptoms are observed, always carry out the following:
- Retrieve all DTCs stored in the restraints control module (RCM) memory and occupant classification sensor (OCS) module memory. Refer to RETRIEVE/CLEAR CONTINUOUS DTCS .
- Run the On-Demand Self Test to determine what DTCs are currently being sensed by the RCM and OCS module. Refer to ON-DEMAND SELF TEST .
- If the stored DTCs are different than the current DTCs, always repair the current DTCs first.
- If memory displays different continuous DTCs than the On-Demand Self Test, carry out in the following order:
- On-Demand Self Test
- Memory (Retrieve/Clear Continuous DTCs)
A DTC can indicate several concerns. The DTCs are to assist in system diagnosis and are not to be considered definitive. Always refer to the pinpoint test corresponding to the DTC to determine where the concern lies and to repair the concern correctly.
The SRS diagnostics can be divided into 3 sections:
- Diagnostic test modes
- PID/data monitor and record
- Active command modes
