B1B06
B1B06-DRIVER AIRBAG SQUIB 2 CIRCUIT OPEN
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
With the ignition on.
- Set Condition:
The Occupant Restraint Controller (ORC) monitors the resistance of the Driver Squib 2 circuits. The ORC will set this DTC if it detects an open or high resistance on the Driver Squib 2 circuits.
1. DETERMINE ACTIVE OR STORED DTC
NOTE: Make sure that the battery is fully charged.
NOTE: The scan tool, SRS Airbag Load Tool 8443, and DVOM are required to perform the following test.
1. Turn the ignition on.
Does the scan tool display B1B06-DRIVER AIRBAG SQUIB 2 CIRCUIT OPEN DTC?
Yes
- Go To 2
No
- Perform the AIRBAG SYSTEM INTERMITTENT TEST. . Airbag System Intermittent Condition Test
2. CHECK FOR OPEN SQUIB CIRCUITS IN DRIVER 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.
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 the connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool Kit 8443 and SRS Load Tool Jumper 8443-1 or 8443-8 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 B1B06-DRIVER AIRBAG SQUIB 2 CIRCUIT OPEN DTC?
Yes
- Go To 3
No
- Replace the Driver Airbag.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
3. CHECK STEERING CONTROL MODULE (CLOCKSPRING) SQUIB CIRCUITS 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. Disconnect the SRS Load Tool Kit 8443 and Jumper from the Driver Airbag Squib connectors.
2. Disconnect the Steering Control Module C4 connector.
NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Kit 8443 and SRS Load Tool Jumper 8443-19 to the Steering Control Module 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 B1B06-DRIVER AIRBAG SQUIB 2 CIRCUIT OPEN DTC?
Yes
- Go To 4
No
- Replace the Steering Control Module.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
4. CHECK (R63) DRIVER SQUIB 2 LINE 1 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. Disconnect the SRS Load Tool Kit 8443 and Jumper from the Steering Control Module connector.
2. Disconnect the ORC connectors.
NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adapter 8443-32-R to the ORC connectors.
NOTE: The IP Harness is always connected to the right side (C1) of the SRS Load Tool Adapter 8443-32-R.
4. Measure the resistance of the (R63) Driver Squib 2 Line 1 circuit between the Steering Control Module C4 connector cavity 1 and the SRS Load Tool Adapter 8443-32-R cavity C1-14.
Is the resistance below 1.0 Ohm?
Yes
- Go To 5
No
- Repair the (R63) Driver Squib 2 Line 1 circuit for an open.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
5. CHECK (R61) DRIVER SQUIB 2 LINE 2 CIRCUIT FOR AN OPEN
1. Measure the resistance of the (R61) Driver Squib 2 Line 2 circuit between the Steering Control Module C4 connector cavity 2 and the SRS Load Tool Adapter 8443-32-R cavity C1-13.
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 follow these instructions may result in possible serious or fatal injury.
- Replace the ORC.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
No
- Repair the (R61) Driver Squib 2 Line 2 circuit for an open.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
