B1B04
B1B04-DRIVER AIRBAG SQUIB 2 CIRCUIT LOW
- 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 low 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 Load Tool Kit 8443A and DVOM are required to perform the following test.
1. Turn the ignition on.
Select ACTIVE or STORED DTC:
ACTIVE DTC
- Go To 2
STORED DTC
- Perform the AIRBAG SYSTEM INTERMITTENT TEST. Initial Inspection and Diagnostic Overview.
2. CHECK FOR SHORTED 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 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.
2. Connect the SRS Load Tool Kit 8443A and SRS Load Tool Jumper 8443-1 to the Driver Airbag Squib 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.
3. With the scan tool, read the active ORC DTCs.
Does the scan tool display: B1B04-DRIVER AIRBAG SQUIB 2 CIRCUIT LOW?
Yes
- Go To 3
No
- Replace the Driver Airbag.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
3. CHECK THE CLOCKSPRING SQUIB CIRCUITS FOR A SHORT TO GROUND
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 Jumper 8443-1 from the Driver Airbag Squib connectors.
2. Disconnect the Clockspring C4 connector.
NOTE: Check connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Kit 8443A and SRS Load Tool Jumper 8443-19 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: B1B04-DRIVER AIRBAG SQUIB 2 CIRCUIT LOW?
Yes
- Go To 4
No
- Replace the Clockspring.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
4. CHECK (R63) DRIVER SQUIB 2 LINE 1 CIRCUIT AND (R61) DRIVER SQUIB 2 LINE 2 CIRCUIT FOR A SHORT TO GROUND
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 8443A and Jumper from the Clockspring C4 connector.
2. Disconnect the ORC connectors.
NOTE: Check connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adaptor 8443-25 to the ORC connectors.
4. Measure the resistance of the (R63) Driver Squib 2 Line 1 circuit between ground and the SRS Load Tool Adaptor 8443-25 cavity 24-18.
5. Measure the resistance of the (R61) Driver Squib 2 Line 2 circuit between ground and the SRS Load Tool Adaptor 8443-25 cavity 24-17.
Is the resistance below 10k Ohms for either measurement?
Yes
- Repair the Driver Squib 2 circuits with resistance below 10k Ohms for a short to ground.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
No
- 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.
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.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
