  1. Refer to Wiring Diagrams SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.

    Normal Operation and Fault Conditions 

    REFER to: Airbag and Seatbelt Pretensioner Supplemental Restraint System (SRS) - System Operation and Component Description .

    The BCM provides battery voltage to the RCM and OCSM through a FET. The BCM monitors each circuit for a short to voltage or a short to ground. If a fault is detected, the BCM stores the appropriate DTC in memory.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    BCM B00A0:11 Occupant Classification System: Circuit Short To Ground A fault is indicated when the BCM senses a short to ground on the OCSM voltage supply circuit.
    BCM B00A0:12 Occupant Classification System: Circuit Short To Battery A fault is indicated when the BCM senses a short to voltage on the OCSM voltage supply circuit.
    BCM B1123:11 Restraints Ignition relay: Circuit Short To Ground A fault is indicated when the BCM senses a short to ground on the RCM voltage supply circuit.
    BCM B1123:12 Restraints Ignition relay: Circuit Short To Battery A fault is indicated when the BCM senses a short to voltage on the RCM voltage supply circuit.

    Possible Sources 

    • Wiring, terminals or connectors
    • BCM
    • RCM
    • OCSM

  2. WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
  3. NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
  4. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  5. NOTE: 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.
  6. 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 parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
  7. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
