1. Turn the ignition on.
2. Measure the voltage of the TIPM Fuse 27 (supply side) of the fuse to ground.
  Is the voltage above 6.0 volts?
  
  Yes
  - Go To 6
  No
  - Replace the TIPM in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to 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. Reinstall the TIPM Fuse 27.
2. Disconnect the ORC connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) to the ORC harness connectors.
  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. Measure the voltage of the (F100) Fused Ignition Switch Output (Run) circuit between the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) cavity 32-22 and ground.
  Is the voltage above 6.0 volts?
  
  Yes
  
  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 follow these instructions may result in possible serious or fatal injury.
  - Replace the ORC in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 7

TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase all DTCs from all airbag modules.
2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
  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.
3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
5. The following additional checks may assist you in identifying a possible intermittent problem.

  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.
7. With the scan tool, monitor active codes as you work through the following steps.
  WARNING:
  Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.
8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
9. If only stored codes return, continue the test until the problem area has been isolated.
10. In the previous steps you have attempted to recreate the conditions responsible for setting the active DTC in question.
  Does the scan tool display any ACTIVE DTCs?
