B1B20
B1B20-RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT LOW
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the resistance of the Right Curtain Squib 1 circuits.
- Set Condition:
The ORC has detected low resistance on the Right Curtain Squib 1 circuits.
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 B1B20-RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT LOW DTC?
Yes
- Go To 2
No
- Perform the AIRBAG SYSTEM INTERMITTENT TEST. . Airbag System Intermittent Condition Test
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 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 the connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool Kit 8443 and SRS Load Tool Jumper 8443-3 to the Right Side Curtain Airbag connector.
WARNING: Turn the ignition on, then reconnect the 12-volt battery. 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 DTC?
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 AND (R2) RIGHT CURTAIN SQUIB 1 LINE 2 CIRCUIT FOR A SHORT TO GROUND
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 Right Side Curtain Airbag connector.
2. Disconnect the ORC connectors.
NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adapter 8443-32-R 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 of the (R4) Right Curtain Squib 1 Line 1 circuit between ground and the Right Side Curtain Airbag connector.
5. Measure the resistance of the (R2) Right Curtain Squib 1 Line 2 circuit between ground and the Right Side Curtain Airbag connector.
Is the resistance below 10K Ohms on either circuit?
Yes
- Repair the Right Curtain Squib 1 circuits with a 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.
- Replace the ORC.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
