Diagnostic Test

VERIFY THAT DTC B212D IGNITION RUN ONLY INPUT CIRCUIT OPEN IS ACTIVE
NOTE: Ensure the battery is fully charged.
1. Turn the ignition on.
2. Wait 10 seconds.
3. With the scan tool, read Occupant Restraint Controller (ORC) and Occupant Classification Module (OCM) DTCs.
  Does the scan tool display active: B212D IGNITION RUN ONLY INPUT CIRCUIT OPEN?
  
  Yes
  - Go to step 2
  No
  - Go to step 8
INSPECT AIRBAG RUN CIRCUIT FUSE
1. Turn the ignition off.
2. Remove the Fuse 27 from the IPM and inspect the fuse.
  NOTE: Check connectors - Clean and repair as necessary.
  
  Is the fuse open?
  
  Yes
  - Go to step 3
  No
  - Go to step 6

1. Measure the resistance of the (F100) Fused Ignition Switch Output (Run) circuit between the TIPM Fuse 27 (output side) terminal and ground.
  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 TIPM Fuse 27.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
CHECK (F100) FUSED IGNITION SWITCH OUTPUT (RUN) CIRCUIT RESISTANCE WITH ORC C2 CONNECTOR DISCONNECTED
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.

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 connectors.
  NOTE: Check connectors - Clean and repair as necessary.
2. Connect the Load Tool ORC 8443-24 Adaptor to the ORC C2 connector.
3. Measure the resistance of the (F100) Fused Ignition Switch Output (Run) circuit between the TIPM Fuse 27 (output side) terminal and ground.
  Is the resistance below 100.0 ohms?
  
  Yes
  - Go to step 5
  No
  - Replace the ORC in accordance with the Service Information.
  - Replace the TIPM Fuse 27.
  - Perform the ORC VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
CHECK (F100) FUSED IGNITION SWITCH OUTPUT (RUN) CIRCUIT RESISTANCE WITH ORC C2 CONNECTOR DISCONNECTED
1. Disconnect the TIPM C7 connectors.
  NOTE: Check connectors - Clean and repair as necessary.
2. Measure the resistance of the (F100) Fused Ignition Switch Output (Run) circuit between the TIPM Fuse 27 (output side) terminal and ground.
  Is the resistance below 100.0 ohms?
  
  Yes
  - Replace the TIPM in accordance with the Service Information.
  - Replace the TIPM Fuse 27.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Repair the (F100) Fused Ignition Switch Output (Run) circuit for a short to ground.
  - Replace the TIPM Fuse 27.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
CHECK TIPM FUSE 27 SUPPLY SIDE CIRCUIT VOLTAGE

1. Turn the ignition on.
2. Measure the voltage between the TIPM Fuse 27 (supply side) terminal and ground.
  Is the voltage above 6.0 volts?
  
  Yes
  - Go to step 7
  No
  - Replace the TIPM in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
CHECK (F100) FUSED IGNITION SWITCH OUTPUT (RUN) 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 TIPM Fuse 27.
2. Disconnect the ORC connectors.
  NOTE: Check connectors - Clean and repair as necessary.
3. Connect the Airbag Load Tool ORC 8443-24 Adaptor to the ORC C2 harness 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.
4. Measure the voltage of the (F100) Fused Ignition Switch Output (Run) circuit between the 8443-24 Adaptor and ground.
  Is the voltage above 6.0 volts?
  
  Yes
  - Replace the ORC in accordance with the Service Information.
  - Perform the ORC VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Repair the open (F100) Fused Ignition Switch Output (Run) circuit between the ORC module and the IPM Fuse 27.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
TEST FOR INTERMITTENT CONDITION
NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to DIAGNOSTIC CODE INDEX for a complete list of airbag system diagnostic procedures.
1. With the scan tool, record and erase all DTCs from all Airbag modules.
  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.
2. Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chafed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.
3. Reconnect all disconnected components and 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.
  
  Does the scan tool display any ACTIVE DTCs?
  
  Yes
  - Select appropriate diagnostic from DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Diagnosis and Testing and. See DTC-Based Diagnostics/MODULE, Occupant Classification (OCM) - Diagnosis and Testing .
  No
  - No problem found. Erase all codes before returning vehicle to customer.
