What it means
This code identifies a fault associated with the driver seatbelt pretensioner C deployment control. The failure type byte specifies the detected fault; the code does not establish that this is a third-stage tightener.
How it works
The driver seatbelt pretensioner C is part of the SRS and is designed to tighten the driver's belt in a crash. The restraints control module monitors its deployment circuit and stores this code when it detects a fault; the accompanying subfault information gives the failure type. The letter C does not establish that this is a third-stage tightener.
Common causes
Most likely first.
- Pretensioner circuit wiring or connector fault
- Open or short in the deployment circuit
- Faulty pretensioner
- Restraints control module fault
Symptoms
- Airbag or SRS warning light
- Pretensioner may not operate as intended in a crash
How to diagnose it
- Read the SRS module's subfault details and freeze-frame data to identify the circuit condition and when it was detected.
- Inspect the driver belt pretensioner C connections and nearby harness for corrosion, damage, looseness, or pinching.
- Check for other SRS codes that may reveal a shared module power, ground, or connector problem.
- Make the SRS safe using the manufacturer's procedure, then test the driver pretensioner C circuit for the open or short indicated by the subfault.
- If the wiring passes, test the pretensioner C assembly and restraints control module using the manufacturer's diagnostic procedure.
Common fixes
- Secure or repair a loose or corroded driver pretensioner C connector.
- Repair an open, short, or damaged wire in the driver pretensioner C circuit.
- Replace the driver seatbelt pretensioner C assembly if it fails the specified checks.
- Repair or replace the restraints control module if testing confirms a module fault.
Can I keep driving?
The vehicle may be driveable, but the driver's belt pretensioner C may not work as intended in a crash. Wear the belt correctly and arrange prompt SRS diagnosis; do not handle deployment wiring except under the manufacturer's safety procedure.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
