Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to 1. Disconnect the Left Seat Airbag C353 in-line connector (under Left Seat). Check connectors - Clean and repair as necessary. 2. Connect the 8443 Load Tool and 8443-20 Jumper to the Left Seat Airbag C353 in-line connector (Body Side). Turn the ignition on, then reconnect the 12-volt battery. Wait two minutes before proceeding. Failure to 3. With the scan tool, read the active ORC DTCs. Does the scan tool display: B1C29-LEFT SIDE SEAT THORAX SQUIB 1 OPEN? Go To 4 Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to Repair or replace the Left Seat Airbag wiring harness (Side Airbag Jumper). Open Left Seat Airbag circuits between the C353 in-line connector and the Left Seat Airbag connector. 4. CHECK FOR OPEN (R5) LEFT SEAT SQUIB 1 LINE 2 CIRCUIT IN THE BODY HARNESS TO THE SEAT http://alldatapro.com/alldata/pro~v372401349~c46382~r0~od~n/0/138181779/139756261/139756334/139756336/34853741/96340231/96340248/176614761/1 5/8
Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to 1. Disconnect the 8443 Load Tool and Jumper from the C353 in-line connector (body side). 2. Disconnect the ORC connectors. Check connectors - Clean and repair as necessary. 3. Connect the Load Tool ORC 8443-25 Adaptor to the ORC connectors. 4. Measure the resistance of the (R5) Left Seat Squib 1 Line 2 circuit between the ORC 8443-25 Adaptor cavity C2-16 and the C353 in-line connector (body side) cavity 1. Is the resistance below 1.0 ohm? Go To 5 Repair or Replace the (R5) Left Seat Squib 1 Line 2 circuit for an open or high resistance. 5. CHECK FOR AN OPEN (R7) LEFT SEAT SQUIB 1 LINE 1 CIRCUIT IN THE BODY HARNESS http://alldatapro.com/alldata/pro~v372401349~c46382~r0~od~n/0/138181779/139756261/139756334/139756336/34853741/96340231/96340248/176614761/1 6/8
1. Measure the resistance of the (R7) Left Seat Squib 1 Line 1 circuit between the ORC 8443-25 Adaptor cavity C2-15 and the C353 in-line connector (body side) cavity 2. Is the resistance below 1.0 ohm? 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. Repair or Replace the (R7) Left Seat Squib 1 Line 1 circuit for an open or high resistance. 6. CHECKING STORED OR INTERMITTENT CODES Diagnose and repair all active codes before diagnosing stored codes. 1. With the scan tool, record and erase all Airbag System Module DTCs. Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to http://alldatapro.com/alldata/pro~v372401349~c46382~r0~od~n/0/138181779/139756261/139756334/139756336/34853741/96340231/96340248/176614761/1 7/8
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. Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to 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? Perform the appropriate DTC. See: Testing and Inspection. problem found at this time. Erase all codes before returning the vehicle to the customer. http://alldatapro.com/alldata/pro~v372401349~c46382~r0~od~n/0/138181779/139756261/139756334/139756336/34853741/96340231/96340248/176614761/1 8/8
