Diagnostic Test
- 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.
- CHECK FOR OPEN SQUIB CIRCUITS IN PASSENGER AIRBAG 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.
- Disconnect the Passenger Airbag Squib harness connectors.WARNING:
Do not place an intact non-deployed 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.
- Connect the SRS Load Tool Kit (special tool #8443A, SRS Load Tool) and SRS Load Tool Jumper (special tool #8443-8, Jumper, SRS Load) to the Passenger Airbag Squib 3 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.
- With the scan tool, read the active ORC DTCs.
Does the scan tool display: B275E-PASSENGER AIRBAG 3RD SQUIB CIRCUIT OPEN- DTC?
Yes
- Go To 3
No
- Replace the Passenger Airbag in accordance with the Service Information. Refer to AIR BAG, PASSENGER, REMOVAL .
- Perform the RESTRAINTS SYSTEM VERIFICATION. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
- Disconnect the Passenger Airbag Squib harness connectors.
- CHECK THE (R68) PASSENGER SQUIB 3 LINE 1 CIRCUIT FOR AN OPEN
- Disconnect the SRS Load Tool Kit (special tool #8443A, SRS Load Tool) and SRS Load Tool Jumper (special tool #8443-8, Jumper, SRS Load) from the Passenger Airbag Squib harness connectors.
- Disconnect the ORC harness connectors.NOTE:
Check connectors - Clean and repair as necessary.
- Connect the SRS Load Tool Adapter (special tool #8443-28, SRS Load Tool Adapter) to the ORC harness connectors.
- Measure the resistance of the (R68) Passenger Squib 3 Line 1 circuit between the Passenger Airbag Squib connector cavity 2 and the SRS Load Tool Adapter (special tool #8443-28, SRS Load Tool Adapter) cavity C1-B 59.
Is the resistance below 1.0 Ohm?
Yes
- Go To 4
No
- Repair the (R68) Passenger Squib 3 Line 1 circuit for an open.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
- CHECK THE (R66) PASSENGER SQUIB 3 LINE 2 CIRCUIT FOR AN OPEN
- Measure the resistance of the (R66) Passenger Squib 3 Line 2 circuit between the Passenger Airbag Squib connector cavity 1 and the SRS Load Tool Adapter (special tool #8443-28, SRS Load Tool Adapter) cavity C1-B 60.
Is the resistance below 1.0 Ohm?
Yes
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 ORC in accordance with Service Information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
No
- Repair the (R66) Passenger Squib 3 Line 2 circuit for an open.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
- Measure the resistance of the (R66) Passenger Squib 3 Line 2 circuit between the Passenger Airbag Squib connector cavity 1 and the SRS Load Tool Adapter (special tool #8443-28, SRS Load Tool Adapter) cavity C1-B 60.
- CHECKING STORED OR INTERMITTENT CODES 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.
- With the scan tool, record and erase all ORC Control 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.
- 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.
- 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.
- 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.
- 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 diagnostic procedure. Refer to DIAGNOSTIC CODE INDEX .
No
- No problem found at this time. Erase all codes before returning the vehicle to the customer.
- With the scan tool, record and erase all ORC Control Module DTCs.
