Air Bag Control Module: Testing and Inspection
CAUTION:
1. Never attempt to disassemble or repair the SRS-ECU. If faulty, replace it.
2. Do not drop or subject the SRS-ECU to impact or vibration.
If denting, cracking, deformation, or rust are discovered in the SRS-ECU, replace it with a new SRS-ECU. Discard the old one.
3. After deployment of an air bag, replace the SRS-ECU with a new one.
4. Never use an ohmmeter on or near the SRS-ECU, and use only the special test equipment described.
INSPECTION
-
Check the SRS-ECU and brackets for dents, cracks or deformation.
-
Check connector for damage, and terminals for deformation.
CAUTION: If a dent, crack, deformation or rust is discovered, replace the SRS-ECU with a new one.
NOTE: Refer to System Diagnosis for inspection of SRS-ECU for other than physical damage.
To inspect and service the SRS after a collision (whether or not the air bags have deployed), perform the following steps.
SRS AIR BAG CONTROL UNIT (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.
3. Read the data list (fault duration and how many times memories are erased) using the scan tool.
4. Erase the diagnostic trouble codes and after waiting 5 seconds or more read (and write down) all displayed diagnostic trouble codes.
