B1B1B

B1B1B-LEFT SIDE CURTAIN SQUIB 1 CIRCUIT SHORTED TOGETHER





For a complete wiring diagram, refer to the wiring information Electrical Diagrams.

- When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the resistance of the Left Curtain Squib 1 circuits.

- Set Condition:
The ORC has detected low resistance between the Left Curtain Squib 1 circuits.





1. DETERMINE ACTIVE OR STORED DTC

NOTE: Make sure 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 ignition on.
2. With the scan tool, read the active ORC DTCs.

Does the scan tool display B1B1B LEFT SIDE CURTAIN SQUIB 1 CIRCUIT SHORTED TOGETHER DTC?

Yes

- Go To 2

No

- Perform the AIRBAG SYSTEM INTERMITTENT TEST. .

2. CHECK FOR SHORTED SQUIB CIRCUITS IN LEFT SIDE CURTAIN 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 Left Side Curtain Airbag connector located in the "D" post.

WARNING: Do not place an intact undeployed curtain 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 the connectors - Clean and repair as necessary.

2. Connect the SRS Load Tool Kit 8443 and SRS Load Tool Jumper 8443-3 to the Left Side Curtain Airbag connector.

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 B1B1B LEFT SIDE CURTAIN SQUIB 1 CIRCUIT SHORTED TOGETHER DTC?

Yes

- Go To 3

No

- Replace the Left Side Curtain Airbag.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

3. CHECK (R3) LEFT CURTAIN SQUIB 1 LINE 1 CIRCUIT FOR A SHORT TO (R1) LEFT CURTAIN SQUIB 1 LINE 2 CIRCUIT





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 SRS Load Tool Jumper from the Left Side Curtain Airbag 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 8443-32-R Adapter.

4. Measure the resistance between the (R3) Left Curtain Squib 1 Line 1 circuit and the (R1) Left Curtain Squib 1 Line 2 circuit at the Left Side Curtain Airbag connector.

Is the resistance below 10K Ohms?

Yes

- Repair the (R3) Left Curtain Squib 1 Line 1 circuit for a short to the (R1) Left Curtain Squib 1 Line 2 circuit.
- 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.

- Replace the ORC.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
