Pinpoint Test

WARNING: Do not handle, move or change the original horizontal mounting position of the RCM while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy® and cause serious personal injury or death.

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: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.

NOTE: Install new components only when directed to do so in the pinpoint test.

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog Advantage or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

RETRIEVE RCM DTCs
1. Ignition ON.
2. Using a scan tool, perform RCM self-test to retrieve DTCs .
Was DTC B11D8:12 or B11D8:14 retrieved on-demand during self-test?
1. Yes:
  - This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during the self-test.
  - For DTC B11D8:14, GO to 2 .
  - For DTC B11D8:12, GO to 4.
2. No
  - This is an intermittent fault when present as a CMDTC only. GO to 7.
