Procedures





SRS-ECU
1. Check the SRS-ECU case and brackets for dents, cracks or deformation.
2. Check the connector for damage, and the terminals for deformation.






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

SRS AIR BAG CONTROL UNIT MEMORY CHECK
1. Connect the scan tool to the data link connector then check diagnosis codes.

CAUTION: Turn the ignition switch off 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 diagnosis unit. Inspect and, if necessary, repair the body wiring harness before proceeding.

3. Read the service data (fault duration and how many times the memory was erased) using the scan tool.

NOTE:
- Maximum stored period: 9999 minutes (approximately 7 days)
- Maximum number of times to be stored: 250

4. Erase the diagnostic trouble codes then wait 45 seconds or more, read and write down all displayed diagnostic trouble codes.
