What it means
The restraint module monitors the deployment circuit for the third-row right seatbelt pretensioner C. It sets this code when the circuit’s measured electrical characteristics are outside the expected range.
At a glance
- Usually lights the airbag (SRS) or body-system warning light
How it works
The restraint control module monitors the deployment circuit for the third-row right seatbelt pretensioner C, which tightens the belt in a crash. This code is stored when the circuit’s electrical reading falls outside the expected range, so the module may not be able to deploy that pretensioner correctly.
Common causes
Most likely first.
- Open or short in pretensioner circuit
- Damaged wiring or connector
- Failed pretensioner inflator
- Fault in the restraint control module
Symptoms
- Warning light or symbol related to the affected system
- Comfort or safety function impaired
How to diagnose it
- Use a restraint-capable scan tool to confirm B00E6, note related restraint codes, and save freeze-frame data before clearing anything.
- Check the third-row right seatbelt and nearby trim for signs of impact damage, moisture, or recent repair that could have disturbed the circuit.
- With the restraint system made safe according to the vehicle maker’s instructions, inspect the pretensioner C wiring and connectors for looseness, corrosion, pin damage, or pinched insulation.
- Use the manufacturer’s approved procedure and test equipment to check the third-row right pretensioner C circuit for an open or short; do not probe the inflator directly with an ordinary meter.
- If the wiring checks pass, have the pretensioner and restraint control module tested with the specified diagnostic procedure.
Common fixes
- Repair damaged wiring or secure a loose third-row right pretensioner C connector using the approved procedure.
- Replace a damaged connector or harness section in the pretensioner C circuit.
- Replace the third-row right pretensioner assembly if testing confirms its inflator has failed.
- Repair or replace the restraint control module only if diagnosis confirms a module fault.
Can I keep driving?
Treat this as a restraint-system fault: the third-row right pretensioner C may not tighten its belt in a crash, and other restraint functions may also be affected. Avoid carrying a passenger in that seat until the fault is repaired, and do not handle or electrically test the inflator without the maker’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
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
