Air Bag Control Module: Testing and Inspection

To inspect and service the SRS after a collision (whether or not the air bags have deployed), perform the following steps.

SRS-ECU MEMORY CHECK
1. Connect the scan tool to the data link connector (16-pin).

CAUTION: Turn off ignition switch before connecting or disconnecting the scan tool.

2. Read (and write down) all displayed diagnostic trouble codes.

NOTE: If the battery power supply has been disconnected or disrupted by the collision, the scan tool cannot communicate with the SRS-ECU. Check the battery then inspect and, if necessary, repair the body wiring harness before proceeding further.
