PINPOINT TEST T: DTCs B00D5:11, B00D5:12 AND B00D5:13

WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (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.
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 taking 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: Only disconnect or reconnect Supplemental Restraint System (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 parts catalog 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.

    • Is the voltage greater than 10 volts? 
      • Yes  : GO to  T6.
      • No  : VERIFY Body Control Module (BCM) fuse 41 (7.5A) is OK. If OK, REPAIR circuit CBP41 (BU). If not OK, REFER to the Wiring Diagrams information to identify the possible causes of the circuit short. GO to  T11.
  6. T6 CHECK THE PAD INDICATOR 
    • Ignition OFF.
    • Connect: PAD Indicator C2355.
    • Connect a fused jumper wire between RCM C310A-22, circuit RR116 (BN/GN), harness side and ground.

    • Does the PAD indicator illuminate? 
  7. T7 CHECK THE PAD INDICATOR CIRCUIT FOR A SHORT TO VOLTAGE 
  8. T8 CHECK THE RCM 
    NOTE: This pinpoint test step attempts to change the fault reported by the RCM by inducing a different fault condition. If the fault reported changes, this indicates the RCM is functioning correctly and is not the source of the fault.
  9. T9 CONFIRM THE RCM FAULT 
    NOTE: Make sure all restraint system components and the RCM electrical connectors are connected before carrying out the self-test. If not, DTCs will be recorded.

      • No  : CHECK for causes of intermittent open, short to ground or short to voltage on circuit CR116 (GN/WH). ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition frequently. ACTIVATE other systems in the same wire harness. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test  . GO to  T11.
  11. T11 CHECK FOR ADDITIONAL SRS DTCs 
    • Ignition OFF.
      WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
