B1B1A
B1B1A-LEFT SIDE CURTAIN SQUIB 1 CIRCUIT OPEN
- When Monitored:
With the ignition on.
- Set Condition:
The Occupant Restraint Controller (ORC) monitors the resistance of the Left Curtain Squib 1 circuits. The ORC will set this DTC if it detects an open or high resistance 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 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 THE 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 8443A and SRS Load Tool Jumper 8443-8 to the Left 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: B1B1A-LEFT SIDE CURTAIN SQUIB 1 CIRCUIT OPEN?
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 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 Left Side Curtain Airbag 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 (R3) Left Curtain Squib 1 Line 1 circuit between the Left Side Curtain Airbag connector cavity 2 and the SRS Load Tool Adaptor 8443-25 cavity 32-9.
Is the resistance below 1.0 Ohm?
Yes
- Go To 4
No
- Repair the (R3) Left Curtain Squib 1 Line 1 circuit for an open. Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
4. CHECK (R1) LEFT CURTAIN SQUIB 1 LINE 2 CIRCUIT FOR AN OPEN
1. Measure the resistance of the (R1) Left Curtain Squib 1 Line 2 circuit between the Left Side Curtain Airbag connector cavity 1 and the SRS Load Tool Adapter 8443-25 cavity 32-10.
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 (R1) Left Curtain Squib 1 Line 2 circuit for an open.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
