Diagnostic Test

VERIFY THAT DTC U0175-LOST COMMUNICATION W/RIGHT SIDE SATELLITE ACCELERATION SENSOR 1
NOTE: Make sure the battery is fully charged.
1. Turn the ignition on.
2. With the scan tool, read ORC DTCs.
  Does the scan tool display active: U0175- LOST COMMUNICATION W/RIGHT SIDE SATELLITE ACCELERATION SENSOR 1?
  
  Yes
  - Go to step 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

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 Right Side Impact Sensor 1 connector.
2. Disconnect 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.
3. Measure the voltage of the (R14) Right Side Impact Sensor 1 Signal circuit and (R16) Sensor Ground circuit at the Right Side Impact Sensor 1 connector and ground.
  Is there any voltage present?
  
  Yes
  - Repair the (R14), (R16) Right Side Impact Sensor 1 circuits for a short to battery.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Go to step 3
CHECK THE (R14) RIGHT 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 (R14) Right Side Impact Sensor 1 Signal circuit between the Right Side Impact Sensor 1 connector and ground.
  Is the resistance below 100K Ohms?
  
  Yes
  - Repair the (R14) Right Side Impact Sensor 1 Signal circuit for a short to ground.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Go to step 4
CHECK THE (R14), (R16) RIGHT SIDE IMPACT SENSOR CIRCUITS FOR A SHORT TOGETHER

1. Measure the resistance between the (R14) Right Side Impact Sensor 1 Signal and (R16) Sensor Ground circuits at the Right Side Impact Sensor 1 connector.
  Is the resistance below 100K Ohms?
  
  Yes
  - Repair the (R14), (R16) Right Side Impact Sensor 1 circuits shorted together.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Go to step 5
CHECK THE (R16) RIGHT SIDE IMPACT SENSOR 1 GROUND CIRCUIT FOR AN OPEN OR HIGH RESISTANCE

1. Connect the SRS Load Tool Adapter 8443-24 to the Occupant Control Module connector.
2. Measure the resistance of the (R16) Right Side Impact Sensor 1 Ground circuit between the Right Side Impact Sensor 1 connector and the SRS Load Tool Adapter 8443-24.
  Is the resistance below 1 Ohm?
  
  Yes
  - Go to step 6
  No
  - Repair the (R16) Right Side Impact Sensor 1 Ground circuit for an open or high resistance.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
CHECK THE (R14) RIGHT SIDE IMPACT SENSOR 1 CIRCUIT FOR AN OPEN OR HIGH RESISTANCE

1. Measure the resistance of the (R14) Right Side Impact Sensor 1 Signal circuit between the Right Side Impact Sensor 1 connector and the SRS Load Tool Adapter 8443-24.
  Is the resistance below 1 Ohm?
  
  Yes
  - Go to step 7
  No
  - Repair the (R14) Right Side Impact Sensor 1 Signal circuit for an open or high resistance.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
CHECK OPERATION OF THE RIGHT SIDE IMPACT SENSOR 1
1. Replace the Right Side Impact Sensor 1.
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 Right Side Impact Sensor 1 DTC return?
  
  Yes
  - Replace the Occupant Restraint Controller in accordance with Service Instructions.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Repair is complete.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
