What it means

B00F2 is the generic code for a fault in the deployment control of the second row left inflatable seat belt. The restraint control module checks the deployment circuit for the inflatable belt and sets the code when it sees a reading outside the expected range, such as an open circuit, short or abnormal resistance. The exact fault type depends on the vehicle, and inflatable belts are only fitted to certain models.

Symptoms

Airbag or SRS warning light on the dashboard
Rear left inflatable seat belt may not deploy in a crash, or the system may be disabled by the module
Seat belt or restraint system warning message on some vehicles
Fault may be intermittent and return after disturbing the rear seat or belt
Other rear seat restraint codes may be stored alongside it

Possible causes

Damaged, corroded or loose connector at the rear left seat belt inflator or buckle arealikely
Wiring damage or chafing in the harness under the rear seat or along the sill and C-pillarlikely
Previous seat or trim work that left a connector unplugged or the harness trappedpossible
Faulty inflatable seat belt assembly (inflator or initiator circuit out of range)possible
Low battery voltage or poor earth causing the module to misread the circuitpossible
Fault inside the restraint control module or a software issue on certain modelsrare

How to diagnose

Read all stored and pending codes and note any freeze frame data and other restraint codes, then check whether the fault is current or history
Check battery condition and charging voltage, as low voltage can cause false restraint faults
Visually inspect the rear left seat belt, its connector and the harness under the rear seat and trim for damage, pinching, water or corrosion
Check for signs of recent repairs, accident damage or seat removal in that area
Follow the manufacturer's safety procedure before touching any restraint component: switch off, disconnect the battery and wait the specified time
With the system safely isolated, check connector pins for tension, corrosion and bent terminals, and check the wiring for continuity and shorts using only the manufacturer-approved method; never probe restraint circuits with a standard test lamp
Check the circuit resistance against the manufacturer's data, as procedures and values depend on the model
Clear the code after repair and confirm it does not return, and that the warning light goes out

How to fix

Repair or replace damaged wiring or connectors in the rear left restraint circuit
Reseat and secure connectors, and re-route any trapped harness
Replace the rear left inflatable seat belt assembly if it is confirmed faulty, following the manufacturer's procedure
Correct battery or earth faults that disturb the restraint system voltage
Replace or update the restraint control module only if it is confirmed faulty or the manufacturer lists a calibration update for this fault

Can I keep driving?

High severity

The car can usually be driven, but the rear left inflatable belt may not work properly in a crash, so have it inspected promptly. Avoid carrying passengers in that seat until it is repaired.
