OBD-II fault code

B00F7: Third Row Right Inflatable Seatbelt Deployment Control (Subfault)

What it means

The restraint module monitors the deployment circuit for the third-row right inflatable seatbelt. 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 supervises the deployment circuit for the inflatable seatbelt at the right-hand third-row seating position. It stores B00F7 when that circuit’s electrical characteristics fall outside the expected range, which can indicate a wiring fault or a problem with the belt inflator.

Common causes

Most likely first.

  1. Open or short in inflatable belt deployment circuit
  2. Damaged wiring or connector
  3. Failed belt inflator
  4. 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

  1. Use a compatible scan tool to read restraint-module codes and freeze-frame details, confirming B00F7 is current and identifying any related circuit faults.
  2. Check the restraint warning display and note whether it appears with an occupied third-row right seat, without disturbing restraint connectors.
  3. With the vehicle powered down as specified by the manufacturer, inspect the accessible wiring and connectors for the right third-row belt circuit for damage, corrosion, looseness, or pinched sections.
  4. Have the deployment circuit checked for opens or shorts using the manufacturer’s restraint-system procedure; do not probe or apply power to an inflator circuit.
  5. If wiring checks pass, have the belt inflator and restraint control module assessed using the manufacturer's diagnostic procedure.

Common fixes

  • Repair damaged wiring or secure a loose connector in the right third-row belt circuit, following restraint-system precautions.
  • Correct corrosion or poor terminal contact in the affected connector.
  • Replace the right third-row inflatable seatbelt assembly if its inflator is confirmed faulty.
  • Repair or replace the restraint control module only if its fault is confirmed.

Can I keep driving?

Treat the right third-row inflatable seatbelt as potentially unavailable and avoid carrying a passenger in that position until the restraint fault is diagnosed. The warning may indicate reduced crash protection; arrange prompt repair.

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.
