Pinpoint Test 2

PINPOINT TEST 2: AIR BAG WARNING INDICATOR IS ILLUMINATED CONTINUOUSLY - RESTRAINTS CONTROL MODULE DISCONNECTED OR INOPERATIVE, LOSS OF BATTERY FEED OR LOSS OF SIGNAL GROUND

Normal Operation

NOTE: During normal operation the air bag indicator is lit continuously for 6 seconds after the ignition switch is placed in the RUN position and after five cycles of a lamp fault code (LFC) if a fault exists. Be sure to cycle the ignition switch and look for a 6 second indicator prove-out without LFCs.

The restraints control module (RCM) will communicate diagnostic trouble codes (DTCs) to the WDS or equivalent tester using the data link connector (DLC). If the WDS or equivalent tester displays NO COMMUNICATION when retrieving continuous DTCs, See PINPOINT TEST 2: RESTRAINTS CONTROL MODULE (RCM) DOES NOT RESPOND TO THE DIAGNOSTIC TOOL. Pinpoint Test 2

Possible Causes
An air bag indicator that is illuminated continuously could be caused by one of the following:
- fuse
- circuitry
- the ignition circuit damaged
- the RCM disconnected from the vehicle harness
- a loss of RCM ground circuits
- the RCM inoperative
- the shorting bar or camming beam in connector

WARNING:
- Restraint system diagnostic tools are for service only. Tools must be removed prior to operating the vehicle over the road. Failure to remove restraint system diagnostic tools could result in injury and possible violation of vehicle safety standards
- The air bag restraint system diagnostic tools must be removed and the air bag modules reconnected when the system is reactivated to avoid non-deployment in a collision. Failure to follow these instructions may result in personal injury.
- Never probe the connectors on the air bag module. Doing so can result in air bag deployment. Failure to follow these instructions may result in personal injury.
- The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment. Failure to follow these instructions may result in personal injury.

NOTE:
- After diagnosing or repairing an SRS, remove the restraint system diagnostic tools before operating the vehicle over the road.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
