Diagnostic Test

WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.

DETERMINE ACTIVE OR STORED DTC
NOTE: Make sure that the battery is fully charged.

NOTE: The scan tool, SRS Airbag Load Tool MRL 8443 and DVOM are required to perform the following test.
1. Turn the ignition on.
2. With the scan tool, read the active ORC DTCs.
  Select ACTIVE or STORED DTC:
  
  ACTIVE DTC
  - Go to step 2
  STORED DTC
  - Go to step 1

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 Driver Airbag Squib connectors.
  WARNING: Do not place an intact undeployed airbag face down on a hard surface, the airbag propels into the air if accidentally deployed. Failure to follow these instructions may result in possible serious or fatal injury.
  
  NOTE: Check connectors - Clean and repair as necessary.
2. Connect the 8443 Load Tool and 8443-1 Jumper to the Driver Airbag Squib connectors.
  WARNING: Turn the ignition on, then reconnect the 12-volt battery. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
3. With the scan tool, read the active ORC DTCs.
  Does the scan tool display: B1B05-DRIVER AIRBAG SQUIB 2 CIRCUIT HIGH?
  
  Yes
  - Go to step 3
  No
  - Replace the Driver Airbag in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
CHECK THE CLOCKSPRING SQUIB CIRCUITS FOR A SHORT TO BATTERY

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 8443 Load Tool and Jumper from the Driver Airbag Squib connectors.
2. Disconnect the Clockspring C4 connector.
  NOTE: Check connectors - Clean and repair as necessary.
3. Connect the 8443 Load Tool and 8443-19 Jumper to the Clockspring C4 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. With the scan tool, read the active ORC DTCs.
  Does the scan tool display: B1B05-DRIVER AIRBAG SQUIB 2 CIRCUIT HIGH?
  
  Yes
  - Go to step 4
  No
  - Replace the Clockspring in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
CHECK (R63) DRIVER SQUIB 2 LINE 1 CIRCUIT AND (R61) DRIVER SQUIB 2 LINE 2 CIRCUIT FOR A SHORT TO BATTERY

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 8443 Load Tool and Jumper from the Clockspring connector.
2. Disconnect the ORC connectors.
  NOTE: Check connectors - Clean and repair as necessary.
3. Connect the ORC 8443-25 Adaptor to the ORC 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 (R63) Driver Squib 2 Line 1 circuit between the 8443-25 Adaptor cavity 24-21 and ground.
5. Measure the voltage of the (R61) Driver Squib 2 Line 2 circuit between the 8443-25 Adaptor cavity 24-22 and ground.
  Is there any voltage present for either measurement?
  
  Yes
  - Repair the Driver Squib 2 circuits with voltage present for a short to battery.
  - Perform AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Replace the ORC in accordance with Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

CHECKING STORED OR INTERMITTENT CODES
NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to the DIAGNOSTIC CODE INDEX for a complete list of airbag system diagnostic procedures.
1. With the scan tool, record and erase all Airbag System Module DTCs.
  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 SYSTEM WIRING DIAGRAMS 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.
4. With the scan tool, monitor for active codes while performing the following:
  - Wiggle the wiring harness and connectors of the related airbag circuit.
  - Continue the test until either a code becomes active or the problem area is isolated.
5. In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question causing the intermittent condition.
  Are any ACTIVE DTCs present?
  
  Yes
  - Perform the appropriate DTC. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Diagnosis and Testing .
  No
  - No problem found at this time. Erase all codes before returning the vehicle to the customer.
