  NOTE:
  Make sure the battery is fully charged.
  
  Does the scan tool display an active: B0111-2F-DRIVER REMOTE ACCELERATION SENSOR (SATELLITE) - SIGNAL ERRATIC - DTC?
  
  Yes
  - Go To 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .
CHECK THE (R131), (R151) LEFT SIDE IMPACT SENSOR 1 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 Sensor 1 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 (R131) Left Side Impact Sensor 1 Signal circuit and (R151) Sensor Ground circuit at the appropriate terminal of the Left Side Impact Sensor 1 harness connector and ground.
  Is there any voltage present?
  
  Yes
  - Repair the (R131), (R151) Left Side Impact Sensor 1 circuits for a short to voltage.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
  No
  - Go To 3
CHECK THE (R131) LEFT SIDE IMPACT SENSOR 1 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 (R131) Left Side Impact Sensor 1 Signal circuit between the Left Side Impact Sensor 1 harness connector and ground.
  Is the resistance below 20 Ohms?
  
  Yes
  - Repair the (R131) Left Side Impact Sensor 1 Signal circuit for a short to ground.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
  No
  - Go To 4
CHECK THE (R131), (R151) LEFT SIDE IMPACT SENSOR 1 CIRCUITS FOR A SHORT TOGETHER
1. Measure the resistance between the (R131) Left Side Impact Pressure Sensor Signal circuit and the (R151) Sensor Ground circuits at the Left Side Impact Sensor 1 harness connector.
  Is the resistance below 20 Ohms?
  
  Yes
  - Repair the (R131), (R151) Left Side Impact Sensor 1 circuits shorted together.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
  No
  - Go To 5
CHECK THE (R151) LEFT SIDE IMPACT SENSOR 1 GROUND CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
1. Measure the resistance of the (R151) Left Side Impact Sensor 1 Ground circuit between terminal 2 of the Left Side Impact Sensor 1 harness connector and ground.
  Is the resistance below 1 Ohm?
  
  Yes
  - Go To 6
  No
  - Repair the (R151) Left Side Impact Sensor 1 Ground circuit for an open or high resistance.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
CHECK THE (R131) LEFT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
1. Measure the resistance of the (R131) Left Side Impact Sensor 1 Signal circuit between terminal 1 of the Left Side Impact Pressure Sensor harness connector and ground.
  Is the resistance below 1 Ohm?
  
  Yes
  - Go To 7
  No
  - Repair the (R131) Left Side Impact Sensor 1 Signal circuit for an open or high resistance.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
CHECK OPERATION OF THE LEFT SIDE IMPACT SENSOR 1
1. Replace the Left Side Impact Sensor 1. 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 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 B0111-2F DRIVER DOOR REMOTE ACCELERATION SENSOR (SATELLITE) - SIGNAL ERRATIC return?
  
  Yes
  - Go To 8
  No
  - Repair is complete.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
REPLACE THE OCCUPANT RESTRAINT CONTROLLER
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.

Repair
- Replace the Occupant Restraint Controller in accordance with Service Information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
