Troubleshooting Intermittent Failures
lf there was a malfunction, but it doesn't recur, it will be
stored in the memory as an intermittent failure, and the
SRS indicator will come on.
After checking the DTC, troubleshoot as follows:
1. Read the DTC (see
"Reading the DTC").
2. Erase the DTC memory (see
"Erasing the DTC
Memory").
3. With the shift lever in neutral, startthe engine, and
l e t i t i d l e .
The SRS indicator will come on for about 6 seconds
and then go off.
Shake the wire harness and the connectors, take a
test drive (quick acceleration, quick braking,
cornering), turn the steering wheel fully left and
right, and hold ittherefor 5to 10 seconds. lf the
problem recurs, the SRS indicator will come on.
lf you can't duplicate the intermittent failure, the
svstem is oK at this time.
