Air Bag Control Module: Testing and Inspection

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.
