What it means
B00E2 is the generic code for a fault in the deployment control circuit of the 'B' pretensioner on the third row centre seat belt. The restraint control module checks the resistance and voltage of the squib circuit when it runs its self-test. It set this code because it saw a reading outside the expected range, such as an open circuit, high resistance, or a short to ground or voltage. What 'B' refers to (for example a second pretensioner or a particular belt position) varies by vehicle, so check the model's wiring information.
Symptoms
- Airbag or SRS warning light on and staying on
- Restraint system fault message in the instrument cluster
- Third row centre belt warning or seat occupancy indication behaving oddly
- Fault returns after being cleared
- Other seat belt or airbag codes stored alongside it
Possible causes
- Damaged, loose or corroded connector at the third row centre seat belt or its under-seat/trim connectionlikely
- Wiring damage, chafing or a pinched cable in the rear load area, seat folding mechanism or trim, causing an open circuit or shortlikely
- Previous seat removal, folding or trim work that left a connector unseated or a wire strainedpossible
- Faulty seat belt pretensioner (squib resistance out of specification)possible
- Moisture or corrosion in the rear floor or connector from a water leakpossible
- Fault inside the restraint control module or a software issuerare
How to diagnose
- Read all stored codes and freeze frame or status data, noting whether the fault is current, intermittent or history, and record any other SRS codes before clearing anything
- Check the vehicle's service information for the SRS safety procedure, then isolate the battery and wait the specified time before touching any restraint connectors
- Visually inspect the third row centre belt, its connector, and the wiring through the seat, floor and trim for damage, trapped cables, water ingress or corrosion
- Check that the connector is fully seated and its locking tab is intact, and look for bent, pushed-back or corroded terminals
- Never probe the pretensioner circuit with a test lamp or standard multimeter, as this risks accidental deployment
- Use the manufacturer's recommended method to check circuit resistance, using a suitable test method that does not apply current to the pretensioner
- Check for any applicable technical bulletins or software updates for the restraint module on this model
- After repair, clear the code, reconnect and restore the battery, and run the SRS self-test to confirm it does not return
How to fix
- Repair or replace damaged wiring, following the manufacturer's repair method for SRS wiring
- Clean, re-seat or replace a faulty connector or terminals in the circuit
- Replace the seat belt pretensioner or belt assembly if its resistance or condition is out of specification
- Dry out and treat a water-affected area, then repair any corroded connections and the leak source
- Replace or update the restraint control module only if testing confirms a module fault and the manufacturer calls for it
Can I keep driving?
The car can be driven short distances, but the restraint system may not work as designed in a collision. Avoid carrying anyone in the third row centre seat and have the fault inspected as soon as possible.
