Diagnostic Test

VERIFY THAT DTC B212C-IGNITION RUN/START INPUT CIRCUIT OPEN IS ACTIVE IN THE ORC.
NOTE:
Make sure the battery is fully charged.

NOTE:
When reconnecting airbag system components, turn off the ignition and disconnect the battery.
1. Turn the ignition on.
2. Using a scan tool, read Occupant Restraint Controller (ORC) DTCs.
  Does the scan tool display active: B212C-IGNITION RUN/START INPUT CIRCUIT OPEN?
  
  Yes
  - Go to step 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to STANDARD PROCEDURE .
INSPECT AIRBAG RUN-START FUSE 27
1. Turn the ignition off.
2. Remove and inspect fuse 27 from the rear Power Distribution Center (PDC).
  NOTE:
  Check connectors. Clean and repair as necessary.
  
  Is fuse 27 open?
  
  Yes
  - Go to step 3
  No
  - Go to step 6

WARNING:
Turn the ignition off, disconnect the battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious and fatal injury.
1. Measure the resistance of the (F201) Fused Run Start Relay Output (Run-Start) circuit between ground and fuse 27 terminal (output side).
  Is the resistance below 100.0 Ohms?
  
  Yes
  - Go to step 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 fuse 27.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .

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 both ORC harness connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
2. Connect the special tool #8443-24, 32-Way Adapter to the ORC C2 harness connector.
3. Measure the resistance of the (F201) Fused Ignition Switch Output (Run-Start) circuit between the special tool #8443-24, 32-Way Adapter cavity C2-16 and ground.
  Is the resistance below 100.0 Ohms?
  
  Yes
  - Go to step 5
  No
  
  WARNING:
  If the Occupant Restraint Controller is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and serious or fatal injury.
  - Replace the ORC in accordance with the Service Information.
  - Replace the Airbag Run-Start Fuse.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .

1. Turn the ignition on.
2. If the vehicle is 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.
3. If the vehicle is 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.
4. Measure the voltage of the (F201) Ignition Switch Output (Run-Start) circuit at the Airbag Run-Start fuse terminal (supply side).
  Is the voltage above 6.0 volts?
  
  Yes
  - Go to step 6
  No
  
  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.
  - Repair the open (F201) Ignition Switch Output (Run-Start) circuit.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
