Diagnostic Test

WARNING: This page is about a different car, the 2016 Jeep Wrangler and 2015 Jeep Wrangler. 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 Load Tool Kit (special tool #8443A, SRS Load Tool), and DVOM are required to perform the following test.
1. Turn the ignition on.
2. With the scan tool, read the active ORC DTC.
  Select ACTIVE or STORED DTC:
  
  ACTIVE DTC
  - Go To 2
  STORED DTC
  - Go To 5

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 Left Seat Squib Airbag connector.
  WARNING:
  Do not place an intact non-deployed Seat Squib Airbag face down on a hard surface, the airbag will propel 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 SRS Load Tool Kit (special tool #8443A, SRS Load Tool) and SRS Load Tool Jumper (special tool #8443-1, Jumpers, 2 Pin) to the Left Seat Squib Airbag 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.
3. With the scan tool, read the active ORC DTC.
  Does the scan tool display: B1C29-LEFT SIDE SEAT THORAX SQUIB 1 OPEN?
  
  Yes
  - Go To 3
  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.
  - Replace the Left Seat Squib Airbag in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM 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. Disconnect the SRS Load Tool Kit (special tool #8443A, SRS Load Tool) and SRS Load Tool Jumper (special tool #8443-1, Jumpers, 2 Pin) from the Left Seat Squib Airbag connector.
2. Disconnect the ORC connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adaptor (special tool #8443-32-L, Adapter, SRS Adapter) to the ORC connectors.
4. Measure the resistance of the (R31) Left Seat Squib Line 1 circuit between the Left Seat Squib Airbag connector and the SRS Load Tool Adaptor (special tool #8443-32-L, Adapter, SRS Adapter) cavity C2-6.
  Is the resistance below 1.0 Ohm?
  
  Yes
  - Go To 4
  No
  - Repair the (R31) Left Seat Squib Line 1 circuit for an open or high resistance.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK (R33) LEFT SEAT SQUIB LINE 2 CIRCUIT FOR AN OPEN

1. Measure the resistance of the (R33) Left Seat Squib Line 2 circuit between the Left Side Seat Squib Airbag connector and the SRS Load Tool Adaptor (special tool #8443-32-L, Adapter, SRS Adapter) cavity C2-5.
  Is the resistance below 1.0 Ohm?
  
  Yes
  
  WARNING:
  If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment. 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
  - Repair the (R33) Left Seat Squib Line 2 circuit for an open or high resistance.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECKING STORED OR INTERMITTENT CODES
NOTE:
Diagnose and repair all active codes before diagnosing stored codes. For a complete list of airbag system diagnostic procedures, refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX .
1. With the scan tool, record and erase all Airbag System Module DTC.
  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.
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 DTC present?
  
  Yes
  - Refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX and perform the appropriate diagnostic procedure.
  No
  - No problem found at this time. Erase all codes before returning the vehicle to the customer.
