Pinpoint Test A: The Air Bag Warning Indicator Is Illuminated Continuously
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Always tighten the fasteners of the restraints control module (RCM) and impact sensor (if equipped) to the specified torque. Failure to do so may result in incorrect restraint system operation, which increases the risk of personal injury or death in a crash.
WARNING:
Never probe the electrical connectors on air bag, safety canopy or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
NOTE:
Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE:
Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE:
Supplemental restraint system (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
NOTE:
The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Do not clear any DTCs until all DTCs have been resolved.
- NO
: If the RCM does
communicate with the scan tool, REFER toINSTRUMENT CLUSTER (IC), MESSAGE CENTER, AND WARNING CHIMES
to diagnose the IC module concern.
If the RCM does not communicate with the scan tool, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the no communication concern.
