B0107-11-FRONT PASSENGER PRETENSIONER (ANCHOR) - CIRCUIT SHORT TO GROUND
Special Tools:
For a complete wiring diagram, refer to the Wiring Information.
Theory of Operation
The location of the anchor buckle tensioner is at the base of the B-pillar. The anchor buckle tensioner is an internal part of the seat belt retractor. When powered, the Occupant Restraint Controller (ORC) sends a test current to the squibs to verify the integrity of the squib and wiring. These circuits are maintained in a "floating" configuration at the ORC (connected to neither power nor ground) as protection against inadvertent deployment. Use of the SRS Load Tool (8443A) in the tests below substitutes a suspect squib with a known good component. The 56 Way ACM Adapter (8443-25) provides a test point as well as a method for opening the shorting bar connections within the ORC harness connector. The anchor buckle tensioners can not be repaired and if ineffective or damaged the entire anchor buckle unit is to be replaced. Following any front airbag deployment the anchor buckle tensioners will also be replaced.
- When Monitored:
With the ignition on.
- Set Condition:
The Occupant Restraint Controller (ORC) monitors the resistance of the Passenger Seat Belt Tensioner circuits. The ORC will set this DTC if it detects low resistance on the Passenger Seat Belt Tensioner circuits for 2.6 seconds. The DTC will change from active to stored when the ORC monitoring shows the short to ground circuit fault is gone for 2.6 seconds. The multifunction indicator lamp (MIL) will set in the instrument cluster.
1. DETERMINE ACTIVE OR STORED DTC
NOTE: Make sure that the battery is fully charged.
NOTE: The scan tool, SRS Load Tool (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
- Go To 4
2. CHECK FOR SHORTED PASSENGER SEAT BELT TENSIONER (ANCHOR)
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 Passenger Seat Belt Tensioner (Anchor) harness connector.
NOTE: Check connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool (8443A) and the SRS Load Jumper (8443-8) to the Passenger Seat Belt Tensioner (Anchor) harness 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: B0107-11-FRONT PASSENGER PRETENSIONER (ANCHOR) - CIRCUIT SHORT TO GROUND?
Yes
- Go To 3
No
- Replace the Passenger Seat Belt Tensioner. Seat Belt Retractor - Removal.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.
3. CHECK THE (R56) PASSENGER SEAT BELT TENSIONER (ANCHOR) LINE 1 CIRCUIT AND THE (R54) PASSENGER SEAT BELT TENSIONER (ANCHOR) 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 (8443A)and the SRS Load Jumper (8443-8) from the Passenger Seat Belt Tensioner (Anchor) harness connector.
2. Disconnect the ORC harness connectors.
NOTE: Check connectors - Clean and repair as necessary.
NOTE: After disconnecting the ORC module and the ORC module body harness connector, check the ORC module body harness connector shorting bar pin location. The shorting bar pin location should be down and not visible through the larger center holes of the ORC module body harness connector.
3. Connect the 56 Way ACM Adapter (8443-25) to the ORC C1 harness connector.
4. Measure the resistance of the (R56) Passenger Seat Belt Retractor (Anchor) Line 1 circuit between ground and the 56 Way ACM Adapter (8443-25)cavity 32-12.
5. Measure the resistance of the (R54) Passenger Seat Belt Retractor (Anchor) Line 2 circuit between ground and the 56 Way ACM Adapter (8443-25) cavity 32-11.
Is the resistance below 10k Ohms on either circuit?
Yes
- Repair the Passenger Seat Belt Tensioner (Anchor) circuits with resistance below 10k Ohms for a short to ground.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.
No
- 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. Occupant Restraint Controller - Removal.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.
4. CHECKING STORED OR INTERMITTENT CODES
NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to the complete list of airbag system diagnostic procedures.
1. With the scan tool, record and erase all Airbag System Module DTCs.
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.
2. Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chaffed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.
3. Reconnect all disconnected components and harness 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.
4. With the scan tool, monitor for active codes while performing the following:
- Wiggle the wiring harness and connectors of the related airbag circuit.
- Continue the test until either a code becomes active or the problem area is isolated.
5. In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question/causing the intermittent condition.
Are any ACTIVE DTCs present?
Yes
- Select the appropriate diagnostic procedure.
No
- No problem found at this time. Erase all codes before returning the vehicle to the customer.
