Diagnostic Test

  1. 1) DETERMINE ACTIVE OR STORED DTC 
    NOTE: Ensure that the battery is fully charged.

    Turn the ignition on.

    With the scan tool, read ORC DTC.

    SELECT ACTIVE or STORED DTC: 

    ACTIVE DTC 

    1. Go To  2).

    STORED DTC 

    1. Perform the *RESTRAINTS SYSTEM INTERMITTENT TEST
  2. 2) VERIFY LEFT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT SHORT TO VOLTAGE

    WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

    Disconnect the ORC connectors.

    Disconnect the Left Side Impact Sensor 1 connector.

    NOTE: Check connectors - Clean and repair as necessary.

    Connect the Load Tool ORC 8443-28 Adapter to the ORC connector.

    WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

    Measure the voltage of the Left Side Impact Sensor 1 Signal circuit between the Left Side Impact Sensor 1 connector cavity 1 and ground.

    Is there any voltage present? 

    Yes 

    1. Repair the Left Side Impact Sensor 1 Signal circuit for a short to voltage.
    2. Perform *RESTRAINT SYSTEM VERIFICATION TEST .

    No 

    1. Go To  3).
  3. 3) VERIFY LEFT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT SHORT TO GROUND

    WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

    Measure the resistance of the Left Side Impact Sensor 1 Signal circuit between the Left Side Impact Sensor 1 connector cavity 1 and ground.

    Is the resistance below 100k ohms? 

    Yes 

    1. Repair the Left Side Impact Sensor 1 Signal circuit for a short to ground.
    2. Perform *RESTRAINT SYSTEM VERIFICATION TEST .

    No 

    1. Go To  4).
  4. 4) VERIFY LEFT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT SHORT TO CIRCUIT GROUND

    Measure the resistance between the Left Side Impact Sensor 1 Signal circuit cavity 1 and the Ground circuit cavity 2 of the Left Side Impact Sensor 1 connector.

    Is the resistance below 100k ohms? 

    Yes 

    1. Repair the Left Side Impact Sensor 1 Signal circuit for a short to the Ground circuit.
    2. Perform *RESTRAINT SYSTEM VERIFICATION TEST .

    No 

    1. Go To  5).
  5. 5) CHECK THE LEFT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT FOR AN OPEN

    Measure the resistance of the Left Side Impact Sensor 1 Signal circuit between the Left Side Impact Sensor 1 connector cavity 1 and the ORC 8443-28 Adaptor cavity C1A-29.

    Is the resistance below 1.0 ohm? 

    Yes 

    1. Go To  6).

    No 

    1. Repair the Left Side Impact Sensor 1 Signal circuit for an open or high resistance.
    2. Perform *RESTRAINT SYSTEM VERIFICATION TEST .
  6. 6) VERIFY OPEN GROUND CIRCUIT

    Measure the resistance of the Ground circuit between the Left Side Impact Sensor 1 connector cavity 2 and ground.

    Is the resistance below 1.0 ohm? 

    Yes 

    1. Go To  7).

    No 

    1. Repair the Ground circuit for an open or high resistance.
    2. Perform *RESTRAINT SYSTEM VERIFICATION TEST .
  7. 7) REPLACE THE LEFT SIDE IMPACT SENSOR 

    Replace the Left Side Impact Sensor 1 in accordance with the Service Information.

    Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.

    WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

    With the scan tool, erase all DTC in all Restraint System Modules.

    Turn the Ignition off, wait 15 seconds, then turn the Ignition on.

    Wait one minute before proceeding.

    With the scan tool, read active ORC DTC.

    Does the scan tool display: 9086-LEFT SIDE IMPACT SENSOR 1 SIGNAL ERROR? 

    Yes 

    WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment and serious or fatal injury.
    WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
    1. Replace the ORC in accordance with the Service information.
    2. Perform *RESTRAINT SYSTEM VERIFICATION TEST .

    No 

    1. Repair complete

      Perform *RESTRAINT SYSTEM VERIFICATION TEST .
