Diagnostic Strategies

If there was a malfunction, but it doesn't recur, it will be stored in the memory as an intermittent failure, and the SRS indicator light comes on.

After checking the DTC, troubleshoot as follows:
1. Read the DTC.
2. Erase the DTC memory.
3. With the shift lever in neutral, turn the ignition switch ON (II), and let the engine idle.




4. The SRS indicator light comes on for about 6 seconds and then goes off.




5. Shake the wire harness and the connector, take a test drive (quick acceleration, quick braking, cornering), and turn the steering wheel fully left and right, and hold it there for 5 to 10 seconds to find the cause of the intermittent failure.
If the problem recurs, the SRS indicator light will stay on.
6. If you can't duplicate the intermittent failure, the system is OK at this time.
