Pinpoint Test A : B11CF:11, B11CF:12, B11CF:13, B11CF:1A

WARNING: Do not handle, move or change the original horizontal mounting position of the Restraints Control Module (RCM) while the Restraints Control Module (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: 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, Diagnostic Trouble Codes (DTCs) may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

    Was DTC B11CF:11, B11CF:12, B11CF:13 or B11CF:1A retrieved on-dem and during self-test? 

    1. Yes:  This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-dem and during self-test.

      For DTC B11CF:13 or B11CF:1A, GO to A2

      For DTC B11CF:11, GO to  A8

      For DTC B11CF:12, GO to  A10

    2. No:  This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only.

      For DTC B11CF:13 or B11CF:1A, GO to  A13

      For DTC B11CF:11, GO to  A14

      For DTC B11CF:12, GO to  A15

  2. A2 CHECK THE PASSENGER FRONTAL AIR BAG CAN VENT RESISTANCE (DEPLOY_08_R) PARAMETER IDENTIFICATION (PID) 
    • Using a diagnostic scan tool, view RCM Parameter Identifications (PIDs).
    • Monitor and record the resistance value displayed by the DEPLOY_08_R Parameter Identification (PID).

    Does the Parameter Identification (PID) value read between 1.7 and 2.78 ohms? 

    1. Yes:  GO to  A12
    2. No:  GO to A3
  3. A3 CHECK THE PASSENGER FRONTAL AIR BAG CAN VENT RESISTANCE (DEPLOY_08_R) PARAMETER IDENTIFICATION (PID) WHILE CARRYING OUT THE HARNESS TEST

Record the resistance value indicated by the Parameter Identification (PID).

    Does the Parameter Identification (PID) value read between 1.7 and 2.78 ohms while carrying out the harness test? 

    1. Yes:  DEPOWER the SRS and REPAIR the connector, terminals or wire harness.
