B00F2 — Second Row Left Inflatable Seatbelt Deployment Control Fault

Severity: medium Safe to drive

What B00F2 means

The supplemental restraint system (SRS) module continuously monitors the deployment circuit of the second row left inflatable seatbelt, checking resistance, supply and shorts. B00F2 is set when it finds a fault in that circuit. The module usually disables that restraint and turns on the SRS warning light.

Symptoms

  • SRS or airbag warning light is on or flashing
  • Message about a seatbelt or pretensioner system fault
  • Rear left inflatable belt may be disabled and not deploy in a crash
  • Code returns after being cleared

Possible causes

  1. Wiring harness shorted to battery voltage or ground
  2. Damaged, corroded or loose connector under the seat or in the pillar
  3. Faulty inflatable seatbelt or pretensioner module
  4. Internal SRS module fault
  5. Harness damage from prior repairs, seat removal or a collision

How to diagnose

  1. Scan all modules with an SRS-capable tool and review freeze frame; note any other airbag or belt codes
  2. Inspect the rear left seat, belt and the wiring under the seat for damage, pinching or signs of earlier repairs
  3. Check the belt circuit connectors for locking, corrosion and bent or loose pins
  4. Disconnect the battery and wait the manufacturer's specified time before any measurements to prevent accidental deployment
  5. Test circuit resistance and check for shorts to ground and to voltage per the wiring diagram, never applying power to the squib
  6. Review the SRS module live data for this device
  7. Clear the code and see if it returns; if it does with good wiring, suspect the belt or the module

Common fixes

  • Repair or replace the damaged wiring harness section
  • Clean or replace the connector and terminals
  • Replace the second row left inflatable seatbelt assembly
  • Replace or reprogram the SRS module if the circuit tests good

Questions and answers

What does B00F2 mean?

The SRS module detected a fault in the control circuit of the rear left inflatable seatbelt. That restraint may be disabled as a result.

Can I drive with B00F2?

Yes, the car will still drive normally. But that seating position may not be protected properly in a crash, so get it fixed soon.

Can I fix B00F2 myself?

You can visually check connectors and wiring, but airbag and belt circuits contain pyrotechnic charges and are dangerous to work on. Testing and replacement are best left to a professional.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
