B1B19-LEFT SIDE CURTAIN SQUIB 1 CIRCUIT HIGH

Special Tools:










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 voltage on the Left Curtain Squib 1 circuits. The ORC will set this DTC if it detects voltage on the Left 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 , 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 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.

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 and SRS Load Tool Jumper to the Left Side Curtain Airbag 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: B1B19-LEFT SIDE CURTAIN SQUIB 1 CIRCUIT HIGH?

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 AND (R1) LEFT CURTAIN SQUIB 1 LINE 2 CIRCUIT FOR A SHORT TO BATTERY





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 and Jumper from the Left Side Curtain Airbag connector.
2. Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.

3. Connect the SRS Load Tool Adapter to the ORC connectors.
4. Measure the voltage of the (R3) Left Curtain Squib 1 Line 1 circuit between the SRS Load Tool Adapter adaptor cavity 9 and ground.
5. Measure the voltage of the (R1) Left Curtain Squib 1 Line 2 circuit between the SRS Load Tool Adapter adaptor cavity 10 and ground.

Is there any voltage present on either circuit?

Yes

- Repair the Left Curtain Squib 1 circuits with voltage present for a short to battery.
- 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 take the proper precautions can result in accidental airbag deployment. 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.
