Component Service
If the SRS components are to be removed or replaced as a result of maintenance, troubleshooting, follow the appropriate procedure for the component.
Caution
1. SRS components should not be subjected to heat over 93C (200F), so remove the SRS-ECU, air bag module and clock spring before drying or
baking the vehicle after painting. Recheck SRS system operability after re-installing them.
2. If the SRS components are removed for the purpose of inspection, sheet metal repair, painting, etc., they should be stored in a clean, dry place
until they are reinstalled.
Collision Repair Procedures
1. Inspect case and brackets for dents, cracks, deformities, or rust. SRS may not activate properly if SRS-ECU is improperly installed.
2. Inspect SRS-ECU connectors for damaged or deformed terminals.
3. Inspect lock lever for damage or rust.
Perform the following steps to inspect and service the SRS after a collision, whether or not an air bag has been deployed:
1. Connect scan tool to diagnostic check connector.
2. Read all displayed DTCs. If battery power supply has been disconnected or disrupted by collision, scan tool cannot communicate with SRS
diagnosis unit. Inspect, and if necessary, repair body wiring harness before proceeding further.
3. Read service data, then erase DTCs.
4. Read and record all DTCs displayed after 45 seconds. Refer to "Diagnostic Trouble Codes" for DTC diagnosis.
