B007F-13-PASSENGER SEATBELT RETRACTOR PRETENSIONER - CIRCUIT OPEN
Special Tools:
For a complete wiring diagram, refer to the Wiring Information.
Theory of Operation
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 module (connected to neither power nor ground) as protection against inadvertent deployment. Use of the (8443A) in the tests below substitutes a suspect squib with a known good component.
- When Monitored:
The ORC sends out a 40 mA diagnostic current on each squib voltage supply circuit at power up and every 500 ms thereafter while the ignition is in on. The module then monitors the data return wire to determine the state of the circuit.
- Set Condition:
This DTC sets when the ORC detects an open on the squib circuit for more than 2.5 seconds. This DTC transitions from active to stored when the module sees a recovery from an open condition for greater than 2.5 seconds.
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.
1.
NOTE: The use of a approved special tool or Digital Multimeter such as a Fluke Meter that will not apply more than 20 milliamperes to a circuit are the only measurement tools to be used.
NOTE: Probing of the circuit cavities at the ORC Module C1-A, C1-B, or C2-A body harness connectors is only to be done with a approved test lead from the (10159) and use test lead 10159-6. Or a comparable test lead to prevent vehicle wiring harness connector damage during diagnostic procedures.
DETERMINE ACTIVE OR STORED DTC
NOTE: Make sure the battery is fully charged.
1. Turn the ignition on.
2. With the scan tool, read all active ORC DTCs.
Is the DTC active or stored?
ORC - ACTIVE DTC
- Go To 2
ORC - STORED DTC
- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test.
2. CHECK FOR PASSENGER SEAT BELT RETRACTOR PRETENSIONER CIRCUIT 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 Passenger Seat Belt Retractor Pretensioner connector.
NOTE: Check the connectors - Clean and repair as necessary.
2. Connect the (8443A) and the (8443-8) to the Passenger Seat Belt Retractor Pretensioner connector.If the vehicle is equipped with the standard key ignition, follow this ignition on warning.
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.
If the vehicle is equipped with the keyless ignition, follow this ignition on warning.
WARNING: Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. 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: B007F-13-PASSENGER SEATBELT RETRACTOR PRETENSIONER - CIRCUIT OPEN?
Yes
- Go To 3
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 Passenger Seat Belt Retractor Pretensioner. Seat Belt Retractor - Removal.
- Perform the RESTRAINT SYSTEMS VERIFICATION TEST. Restraints System Verification Test.
3. CHECK (R506) PASSENGER SEAT BELT RETRACTOR PRETENSIONER 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 (8443A) and the (8443-8) from the Passenger Seat Belt Retractor Pretensioner harness connector.
2. Disconnect the ORC harness connectors.
NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the test leads to the DVOM.
4. Measure the resistance of the (R506) Passenger Seat Belt Retractor Pretensioner Line 1 circuit between the Passenger Seat Belt Retractor Pretensioner connector terminal 1 and the ORC module body harness connector terminal C1-B 95.
Is the resistance below 1.0 Ohm?
Yes
- Go To 4
No
- Repair or replace the (R506) Passenger Seat Belt Retractor Pretensioner Line 1 circuit. Then Go To 4
4. CHECK (R504) PASSENGER SEAT BELT RETRACTOR PRETENSIONER LINE 2 CIRCUIT FOR AN OPEN
1. Measure the resistance of the (R504) Passenger Seat Belt Retractor Pretensioner Line 2 circuit between the Passenger Seat Belt Retractor Pretensioner connector terminal 2 and the ORC module body harness connector terminal C1-B 96.
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 take the proper precautions can result in accidental airbag deployment and serious or fatal injury.
- Replace the ORC. Occupant Restraint Controller - Removal.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.
No
- Repair or replace the (R504) Passenger Seat Belt Retractor Pretensioner Line 2 circuit for and open.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.
