Good
- Fault is intermittent caused by poor contact in the sensor's and/or SRSCM's connector or was repaired and SRSCM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF REPAIR " procedure.
No Good
- Repair or replace as necessary and then, go to "VERIFICATION OF REPAIR " procedure.
