Diagnostic Test

CHECK FOR AN ACTIVE DTC
1. With the scan tool, read ORC DTCs and record on the repair order.
2. Record the Environmental Data.
3. With the scan tool, erase DTCs.
4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read ORC DTCs.
  Did the DTC return?
  
  Yes
  - Go To 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .
  - Probing of the circuit cavities at the ORC Module body harness connectors or vehicle connectors is only to be done with a approved test lead from the test lead 10159-6 or the use of Breakout Box 8443-55 to prevent vehicle wiring harness connector damage during diagnostic procedures.
INSPECT AIRBAG FUSED RUN ONLY CIRCUIT FUSE
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. Turn the ignition off.
2. Remove the Airbag Run Circuit Fuse from the Power Distribution Center and inspect the fuse.
  NOTE:
  Check the connectors - Clean and repair as necessary.
  
  Is the fuse open?
  
  Yes
  - Go To 3
  No
  - Go To 6
CHECK (F100) FUSED RUN RELAY OUTPUT CIRCUIT RESISTANCE
WARNING:
If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.

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 (F100) Run Relay Output circuit between the Airbag Run Relay Output circuit fuse (supply side) terminal and ground.
  Is the resistance below 100.0 Ohms?
  
  Yes
  - Go To 4
  No
  - Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
  - Replace Power Distribution Center Airbag Run Circuit Fuse.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
CHECK (F100) FUSED RUN RELAY OUTPUT CIRCUIT RESISTANCE WITH ORC CONNECTORS DISCONNECTED
WARNING:
If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.

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 ORC harness connectors.
  NOTE:
  Check the connectors - Clean and repair as necessary.
2. Connect the appropriate test lead to the DVOM.
3. Measure the resistance of the (F100) Fused Run Relay Output circuit between the ORC module C2 body harness connector and ground.
  Is the resistance below 100.0 Ohms?
  
  Yes
  - Go To 5
  No
  - Replace the ORC in accordance with the Service Information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
  - Replace the Power Distribution Center Airbag Run Circuit Fuse.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
CHECK (F100) RUN RELAY OUTPUT CIRCUIT VOLTAGE
1. Turn the ignition on.
2. Measure the voltage of the (F100) Run Relay Output circuit at the Airbag Run Circuit fuse terminal (supply side).
  Is the voltage above 6.0 volts?
  
  Yes
  - Go To 6
  No
  - Repair the open (F100) Run Relay Output circuit.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
CHECK (F100) FUSED RUN RELAY OUTPUT CIRCUIT FOR AN OPEN
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. Reinstall the Airbag Run Circuit Fuse.
2. Disconnect the ORC harness connectors.
  NOTE:
  Check the connectors - Clean and repair as necessary.
3. Connect the appropriate test lead to the DVOM.
4. If equipped with the standard key ignition, follow this ignition on warning.
  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.
5. If equipped with the keyless ignition, follow this ignition on warning.
  WARNING:
  Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
6. Measure the voltage of the (F100) Fused Run Relay Output Circuit between the appropriate terminal of the ORC module C2 body harness connector and ground.
  Is the voltage above 6.0 volts?
  
  Yes
  
  WARNING:
  If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.
  - Replace the ORC in accordance with the Service Information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Repair the open (F100) Fused Run Relay Output circuit.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
