Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. VERIFY ACTIVE DTC 
    NOTE:

    Make sure the battery is fully charged.

    1. Turn the ignition on.
    2. With the scan tool, read the ORC DTCs.

      Does the scan tool display active: B012D-64-DRIVER DOOR PRESSURE SENSOR (SATELLITE) - SIGNAL PLAUSIBILITY FAILURE IS ACTIVE?

      Yes 

      • Go To  2

      No 

  2. CHECK THE (R130), (R150) LEFT SIDE IMPACT PRESSURE SENSOR SIGNAL AND GROUND CIRCUITS FOR A SHORT TO VOLTAGE 
    WARNING:

    Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    1. Disconnect the Left Side Impact Pressure Sensor harness connector.
    2. Disconnect the ORC harness connector.
      WARNING:

      Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    3. Measure the voltage of the (R130) Left Side Impact Pressure Sensor Signal circuit and (R150) Left Side Impact Pressure Sensor Ground circuit at the Left Side Impact Pressure Sensor harness connector and ground.

      Is there any voltage present?

      Yes 

      • Repair the (R130), (R150) Left Side Impact Pressure Sensor circuits for a short to voltage.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

      No 

      • Go To  3
  3. CHECK THE (R130) LEFT SIDE IMPACT PRESSURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    WARNING:

    Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    1. Measure the resistance of the (R130) Left Side Impact Pressure Sensor Signal circuit between the Left Side Impact Pressure Sensor connector and ground.

      Is the resistance below 20 Ohms?

      Yes 

      • Repair the (R130) Left Side Impact Pressure Sensor Signal circuit for a short to ground.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

      No 

      • Go To  4
  4. CHECK THE (R130), (R150) LEFT SIDE IMPACT PRESSURE SENSOR CIRCUITS FOR A SHORT TOGETHER 
    1. Measure the resistance between the (R130) Left Side Impact Pressure Sensor Signal and (R150) Left Side Impact Pressure Sensor Ground circuits at the Left Side Impact Pressure Sensor connector.

      Is the resistance below 20 Ohms?

      Yes 

      • Repair the (R130), (R150) Left Side Impact Pressure Sensor circuits shorted together.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

      No 

      • Go To  5
  5. CHECK THE (R150) LEFT SIDE IMPACT PRESSURE SENSOR GROUND CIRCUIT FOR AN OPEN OR HIGH RESISTANCE 
    1. Disconnect the ORC harness connectors.
      NOTE:

      Check connectors - Clean and repair as necessary.

      NOTE:

      Probing of the circuit cavities at the ORC Module body harness connectors is only to be done with a approved test lead from the (special tool #10159, Test Leads, Dedicated), test lead 10159-6. Or a comparable test lead to prevent vehicle wiring harness connector damage during diagnostic procedures.

    2. Connect the test probes to the appropriate ORC harness connector terminal(s).
    3. Measure the resistance of the (R150) Left Side Impact Pressure Sensor Ground circuit between the Left Side Impact Pressure Sensor connector terminal 2 and appropriate cavity of test tool.

      Is the resistance below 1 Ohm?

      Yes 

      • Go To  6

      No 

      • Repair the (R150) Left Side Impact Pressure Sensor Ground circuit for an open or high resistance.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  6. CHECK THE (R130) LEFT SIDE IMPACT PRESSURE SENSOR SIGNAL CIRCUIT FOR AN OPEN OR HIGH RESISTANCE 
    1. Measure the resistance of the (R130) Left Side Impact Pressure Sensor Signal circuit between the Left Side Impact Pressure Sensor harness connector terminal 1 and the appropriate cavity of test tool.

      Is the resistance below 1 Ohm?

      Yes 

      • Go To  7

      No 

      • Repair the (R130) Left Side Impact Pressure Sensor Signal circuit for an open or high resistance.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  7. CHECK OPERATION OF THE LEFT SIDE IMPACT PRESSURE SENSOR 
    1. Replace the Left Side Impact Pressure Sensor in accordance with the Service Information. Refer to SENSOR, IMPACT, REMOVAL .
    2. Reconnect the vehicle body harness to the impact sensor.
    3. Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.
      WARNING:

      Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    4. Connect the scan tool to the Data Link Connector - use the most current software available.
    5. Use the scan tool and erase the stored codes in all airbag system modules.
    6. Turn the Ignition Off, and wait five seconds before turning the Ignition On.
    7. Wait one minute, and read active codes and if there are none present read the stored codes.

      Did the active: B012D-64-DRIVER DOOR PRESSURE SENSOR (SATELLITE) - SIGNAL PLAUSIBILITY FAILURE DTC return?

      Yes 

      WARNING:

      Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

      WARNING:

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