Diagnostic Test

TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
  NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
2. With the scan tool, select ECU view.
  NOTE: A red "X" will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.
  
  Does the scan tool display a red "X" next to the module?
  
  Yes
  - Go to step 2
  No
  - The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals.
(Z911) GROUND CIRCUIT OPEN

WARNING: To avoid possible serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
1. Disconnect the Occupant Restraint Controller Module C2 harness connector.
2. Connect the appropriate Load Tool ACM Adaptor to the ORC connector.
3. Using a 12-volt test light connected to 12-volts, check the (Z911) ground circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 3
  No
  - Repair the (Z911) ground circuit for an open.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure
(F100) FUSED IGNITION SWITCH OUTPUT (RUN) CIRCUIT OPEN OR SHORTED

NOTE: Check the TIPM for any ignition related DTCs before proceeding. If set. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Diagnosis and Testing .

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.
1. Using a 12-volt test light connected to ground, check the (F100) Fused Ignition Switch Output (RUN) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 4
  No
  - Repair the (F100) Fused Ignition Switch Output (RUN) circuit for an open or short.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure
(F200) FUSED IGNITION SWITCH OUTPUT (RUN/START) CIRCUIT OPEN OR SHORTED

1. Using a 12-volt test light connected to ground, check the (F200) Fused Ignition Switch Output (RUN/START) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 5
  No
  - Repair the (F200) Fused Ignition Switch Output (RUN/START) circuit for an open or short.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure
(D55) AND (D54) CAN B BUS CIRCUITS OPEN

WARNING: If the Occupant Restraint Controller is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment and personal injury or death.

NOTE: One open circuit will not cause this condition.
1. Measure the voltage between the (D54) CAN B Bus (-) circuit and ground.
2. Measure the voltage between the (D55) CAN B Bus (+) circuit and ground.
  Is there any voltage present on either circuit?
  
  Yes
  - Replace the Occupant Restraint Controller Module in accordance with the service information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure
  No
  - Repair the (D55) and (D54) CAN B Bus circuits for an open. Inspect the connector for damage.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure
