B1B22

B1B22-RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT OPEN







- When Monitored:
With the ignition on.

- Set Condition:
The Occupant Restraint Controller (ORC) monitors the resistance of the Right Curtain Squib 1 circuits. The ORC will set this DTC if it detects an open or high resistance on the Right Curtain Squib 1 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 OPEN SQUIB CIRCUITS IN RIGHT 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 Right Side Curtain Airbag connector.

WARNING: Do not place an intact uncoupled 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 connectors - Clean and repair as necessary.

2. Connect the SRS Load Tool Kit 8443A and SRS Load Tool Jumper 8443-8 to the Right Side Curtain Airbag 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.

3. With the scan tool, read the active ORC DTCs.

Does the scan tool display: B1B22 RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT OPEN?

Yes

- Go To 3

No

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

3. CHECK (R4) RIGHT CURTAIN SQUIB 1 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 8443A and Jumper from the Right Side Curtain Airbag connector.
2. Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.

3. Connect the SRS Load Tool Adapter 8443-25 to the ORC C1 connector.
4. Measure the resistance of the (R4) Right Curtain Squib 1 Line 1 circuit between the Right Side Curtain Airbag connector cavity 1 and the SRS Load Tool Adapter 8443-25 cavity 32-12.

Is the resistance below 1.0 Ohm?

Yes

- Go To 4

No

- Repair the (R4) Right Curtain Squib 1 Line 1 circuit for an open.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

4. CHECK (R2) RIGHT CURTAIN SQUIB 1 LINE 2 CIRCUIT FOR AN OPEN




1. Measure the resistance of the (R2) Right Curtain Squib 1 Line 2 circuit between the Right Side Curtain Airbag connector cavity 2 and the SRS Load Tool Adapter 8443-25 cavity 32-11.

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.

- 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.

No

- Repair the (R2) Right Curtain Squib 1 Line 2 circuit for an open.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
