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.
