B1B1B
B1B1B-LEFT SIDE CURTAIN SQUIB 1 CIRCUIT SHORTED TOGETHER
For a complete wiring diagram refer to Diagrams/Electrical.
- 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.
Diagnostic Test
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?
YES: Go to 2.
NO: 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 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 connectors - Clean and repair as necessary.
2. Connect the SRS 8443 Load Tool Kit and SRS Load Tool Jumper 8443-3 to the Left Side Curtain Airbag connector.
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.
3. With the scan tool, read the active ORC DTC's.
Does the scan tool display: B1B1B LEFT SIDE CURTAIN SQUIB 1 CIRCUIT SHORTED TOGETHER?
Yes: Go to 3
No: Replace the Left Side Curtain Airbag. Perform AIRBAG SYSTEM VERIFICATION TEST. Occupant Classification Module (OCM) 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 connectors - Clean and repair as necessary.
3. Connect the Load Tool ORC 8443-32-R Adaptor 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 Right 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 AIRBAG SYSTEM VERIFICATION TEST. Occupant Classification Module (OCM) System Verification Test
No: Replace the ORC. Perform AIRBAG SYSTEM VERIFICATION TEST. Occupant Classification Module (OCM) System Verification Test
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.
