Diagnostic Test

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

   Does the scan tool display active: U0171-LOST COMMUNICATION W/UP-FRONT RIGHT SATELLITE ACCELERATION SENSOR?

   Yes 

   • Go to step  2

   No 

   • Go to step  9

1. Disconnect the Front Right Impact Sensor connector.
2. Disconnect the ORC connectors.
3. Connect the ORC 8443-25 Adaptor to the ORC 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.
4. Measure the voltage of the (R80) Front Right Impact Sensor Signal circuit and (R82) Sensor Ground circuit at the Front Right Impact Sensor connector and ground.

   Is there any voltage present?

   Yes 

   • Repair the (R80) and (R82) Front Right Impact Sensor circuits for a short to battery.
   • Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

   No 

   • Go to step  3

1. Measure the resistance of the (R80) and (R82) Front Right Impact Sensor circuits between the Front Right Impact Sensor connector and ground.

   Is the resistance below 100K ohms?

   Yes 

   • Repair the (R80) and (R82) Front Right Impact Sensor circuits for a short to ground.
   • Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

   No 

   • Go to step  4

1. Measure the resistance between the (R80) Front Right Impact Sensor Signal and (R82) Sensor Ground circuit at the Front Right Impact Sensor connector.

   Is the resistance below 100K ohms?

   Yes 

   • Repair the (R80) and (R82) Front Right Impact Sensor circuits shorted together.
   • Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

   No 

   • Go to step  5

1. Measure the resistance of the (R82) Front Right Impact Sensor Ground circuit between the Front Right Impact Sensor connector and the ORC 8443-25 Adaptor.

   Is the resistance below 1 ohm?

   Yes 

   • Go to step  6

   No 

   • Repair the (R82) Front Right Impact Sensor 2 Ground circuit for an open or high resistance.
   • Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

1. Measure the resistance of the (R80) Front Right Impact Sensor Signal circuit between the Front Right Impact Sensor connector and the ORC 8443-25 Adaptor.

   Is the resistance below 1 ohm?

   Yes 

   • Go to step  7

   No 

   • Repair the (R80) Front Right Impact Sensor Signal circuit for an open or high resistance.
   • Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

1. Replace the Front Right Impact Sensor.
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 15 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 Front Right Impact Sensor DTC return?

   Yes 

   • Go to step  8

   No 

   • Repair is complete.
   • Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

If there are no possible causes remaining, view repair.

Repair 

• Replace the Occupant Restraint Controller in accordance with Service Instructions.
• Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

1. With the scan tool, record and erase all DTCs from all Airbag modules.
2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
   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.
3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
5. The following additional checks may assist you in identifying a possible intermittent problem.
6. Reconnect any disconnected components and 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.
7. With the scan tool monitor active codes as you work through the following steps.
   WARNING: Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.
8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
9. If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
10. If only stored codes return continue the test until the problem area has been isolated.
11. In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

    Are any ACTIVE DTCs present?

    Yes 

    • Perform the appropriate DTC. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Diagnosis and Testing .

    No 

    • No problem found at this time. Erase all codes before returning vehicle to customer.
