Diagnostic Test

  1. READ AND RECORD DTCS AND ENVIRONMENTAL DATA - ERASE DTCS AND CHECK FOR THE DTC TO RETURN 
    1. With the scan tool, read ORC DTCs and record on the repair order.
    2. With the scan tool, run a Vehicle Scan Report or record the Environmental Data.
    3. With the scan tool, erase DTCs.
    4. Turn the ignition off for at least 10.0 seconds.
    5. Turn the ignition on.
    6. Using the recorded Environmental Data and the When Monitored Conditions, operate the vehicle in the conditions that set the DTC.
    7. With the scan tool, read ORC DTCs.

    Did the DTC return?

    Yes 

    • Go To  2

    No 

  2. ISOLATE AND CHECK THE PASSENGER AIRBAG DISABLE (PAD) LAMP DRIVER CIRCUITS FOR A SHORT TO VOLTAGE 
    CAUTION:

    Probing of the circuit cavities at the Occupant Restraint Controller (ORC) body harness connectors and in-line connectors using test kit 2022900080 for back probing the terminal will prevent vehicle wiring harness connector damage during diagnostic procedures.

    1. Turn the ignition off.
    2. Isolate the circuit by disconnecting the Electronic Control Unit (ECU) and every component harness connector containing the circuit(s) being tested. Note:  Use the wiring diagram as a guide to follow the path of the circuit
    3. Turn the ignition on.
    4. Using a DVOM, measure the voltage of the circuit(s) being tested at the component harness connector.

    Is there any voltage present on either circuit?

    Yes 

    • Repair the Passenger Airbag Disable (PAD) Lamp Driver circuit(s) for a short to voltage
    • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

    No 

    • Go To  3
  3. ISOLATE AND CHECK THE PASSENGER AIRBAG DISABLE (PAD) LAMP DRIVER CIRCUITS FOR A SHORT TO GROUND 
    1. The ignition must be off when checking a circuit for continuity to ground.
    2. Isolate the circuit by disconnecting the Electronic Control Unit (ECU) and every component harness connector containing the circuit(s) being tested. Note:  Use the wiring diagram as a guide to follow the path of the circuit.
    3. Connect the negative lead of the DVOM to a known good ground.
    4. With the positive lead of the DVOM, probe the circuit(s) being tested at the component harness connector and check for continuity between the circuit(s) and ground.
    NOTE:

    There should be no continuity between ground and the circuit being tested.

    Is there continuity between ground and the circuit being tested?

    Yes 

    • Repair the Passenger Airbag Disable (PAD) Lamp Driver circuit(s) for a short to ground.
    • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

    No 

    • Go To  4
  4. ISOLATE AND CHECK THE PASSENGER AIRBAG DISABLE (PAD) LAMP DRIVER CIRCUITS FOR AN OPEN OR HIGH RESISTANCE 
    1. The ignition must be off when checking the continuity of a circuit.
    2. Isolate the circuits by disconnecting the Electronic Control Unit (ECU) and the component harness connector containing the circuit being tested. Note:  Use the wiring diagram as a guide to follow the path of the circuit.
    3. Before measuring the resistance of any circuit, first measure the resistance between the two leads of the DVOM. Note:  The meter leads can add resistance to the measurement value.
    4. Connect one lead of the DVOM to the circuit being tested at the component harness connector.
    5. Connect the other lead to the circuit being tested at the ECU harness connector and measure the resistance of the circuit.
    NOTE:

    When probing a circuit at an Electronic Control Unit (ECU) harness connector, always use an appropriate back probing tool to prevent any possible damage to the ECU terminals.

    Is the resistance below 1.0 Ohm on both circuits?

    Yes 

    • Go To  5

    No 

    • Repair the Passenger Airbag Disable (PAD) Lamp Driver circuit(s) for an open or high resistance.
    • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  5. REPLACE THE PASSENGER AIRBAG DISABLE LAMP 
    1. Replace the PAD Lamp in accordance with the Service Information.
    2. Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

      Did the DTC return?

      Yes 

      WARNING:

      If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.

      No
