Diagnostic Test

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

   Does the scan tool display active: B1B71-UP-FRONT RIGHT SATELLITE ACCELERATION SENSOR INTERNAL?

   Yes 

   • Go to step  2

   No 

   • Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

1. Disconnect the Front Right Impact Sensor connector.
2. Disconnect the ORC C2 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 (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, R82) Front Right Impact Sensor circuits for a short to voltage.
   • Perform the RESTRAINTS 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) Front Right Impact Sensor Signal circuit between the Front Right Impact Sensor connector and ground.

   Is the resistance below 100K Ohms?

   Yes 

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

   No 

   • Go To  4

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

   Is the resistance below 100K Ohms?

   Yes 

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

   No 

   • Go To  5

1. Connect the SRS Load Tool Kit 8443A to the ORC C2 connector.
2. Measure the resistance of the (R82) Front Right Impact Sensor Ground circuit between the Front Right Impact Sensor connector and the SRS Load Tool Kit 8443A.

   Is the resistance below 1 Ohm?

   Yes 

   • Go to step  6

   No 

   • Repair the (R82) Front Right Impact Sensor Ground circuit for an open or high resistance.
   • Perform the RESTRAINTS 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 SRS Load Tool Kit 8443A.

   Is the resistance below 1 Ohm?

   Yes 

   • Go To  7

   No 

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

1. Replace the Front Right Impact Sensor in accordance with the Service Information.
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 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  8

   No 

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

Repair 

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