What it means
The restraint module monitors the deployment circuit for the third-row center 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 checks the deployment circuit for the third-row center seatbelt pretensioner C, which helps tighten the center belt in a crash. It sets B00E8 when the circuit’s electrical characteristics are outside the expected range, which can prevent reliable deployment of this pretensioner.
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
- Scan the restraint module for B00E8 and related codes, and save freeze-frame or event information before clearing the fault.
- Inspect the third-row center belt mounting and surrounding trim for impact damage, moisture, or work that could have disturbed the circuit.
- After following the manufacturer’s restraint-system disable instructions, examine the pretensioner C connector and wiring for loose or corroded terminals, damaged insulation, or pinched wires.
- Check the third-row center pretensioner C circuit for an open or short using the maker’s specified test equipment and method; do not test the inflator with an ordinary meter.
- If wiring and connectors pass, follow the approved diagnostic flow to assess the center pretensioner assembly and restraint control module.
Common fixes
- Reconnect or repair damaged wiring at the third-row center pretensioner C circuit as specified by the manufacturer.
- Replace a faulty connector or damaged harness section identified during inspection or testing.
- Replace the third-row center pretensioner assembly if the inflator fails the approved test.
- Repair or replace the restraint control module only after its fault is verified.
Can I keep driving?
The third-row center pretensioner C may not tighten the belt during a collision, reducing protection for that seating position. Do not use that seat until the restraint fault is resolved, and have inflator handling done under the vehicle 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.
