B1B20






B1B20-RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT LOW







- 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 low 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 SHORTED 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 non-deployed 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: B1B20-RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT LOW?

Yes

- Go To 3

No

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

3. CHECK THE (R4) RIGHT CURTAIN SQUIB 1 LINE 1 CIRCUIT AND (R2) RIGHT CURTAIN SQUIB 1 LINE 2 CIRCUIT FOR A SHORT TO GROUND

3. Connect the SRS Load Tool Adapter 8443-25 to the ORC connectors.
4. Measure the resistance of the (R4) Right Curtain Squib 1 Line 1 circuit between SRS Load Tool Adapter 8443-25 cavity 32-12 and ground.
5. Measure the resistance of the (R2) Right Curtain Squib 1 Line 2 circuit between SRS Load Tool Adapter 8443-25 cavity 32-11 and ground.

Is the resistance below 10k Ohms on either circuit?

Yes

- Repair the Right Curtain Squib 1 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.
