Pinpoint Test P: B00D5:01

  1. Normal Operation and Fault Conditions 

    The RCM controls the PAD indicator via a CAN message to the HVAC control module. More more information, REFER to: Airbag and Seatbelt Pretensioner Supplemental Restraint System (SRS) - System Operation and Component Description .

    The HVAC control module briefly activates each PAD indicator LED in the overhead console to prove-out and verify correct functional operation of the PAD indicator to the occupants.

    The HVAC control module continuously monitors the PAD indicator circuits for the following faults:

    • Open circuit
    • Short to voltage
    • Short to ground
    • Faulted overhead console

    If a fault is detected, the HVAC control module stores DTC B00D5:01 in memory and sends a message to the RCM. The RCM stores DTC B00D5:01 in memory and sends a message to the IPC to illuminate the airbag warning indicator.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    HVAC B00D5:01 Restraint System Passenger Disable Indicator: General Electrical Failure The HVAC control module sets this DTC when it senses a fault on the PAD indicator "OFF" LED circuit.
    RCM B00D5:01 Restraint System Passenger Disable Indicator: General Electrical Failure The RCM sets this DTC when the HVAC control module reports a fault on the PAD indicator "OFF" LED circuit.

    Possible Sources 

    • Wiring, terminals or connectors
    • Overhead console
    • HVAC control module

    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.
    NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to 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 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 parts catalog 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.
