What it means
B00E0 is a generic body code for a fault in the deployment control circuit of the third row left seat belt pretensioner 'B'. The restraint control module checks the squib circuit, including its resistance, wiring and driver, and sets the code when the readings are outside the expected range. The exact fault type (open circuit, short to ground, short to voltage, or resistance out of range) and what 'B' refers to (such as a second stage or second device) depend on the vehicle.
Symptoms
- Airbag or SRS warning light on the dashboard
- Third row left seat belt pretensioner may not fire in a crash
- Seat belt warning light or message for the third row
- Other SRS codes stored alongside it
- Intermittent warning light after the third row seats are moved or folded
Possible causes
- Damaged, pinched or chafed wiring to the third row left pretensioner, often where the seat folds or slideslikely
- Poor connection or corrosion at the pretensioner connector or an in-line connector under the seat or trimlikely
- Faulty pretensioner (squib) with out-of-range resistancepossible
- Wiring damage or connector disturbance after trim removal, seat removal or bodywork repairpossible
- Previous crash or deployment event where the pretensioner or wiring was not replacedpossible
- Fault in the restraint control module driver circuit or its connectorsrare
- Water ingress in the rear floor or side trim area affecting the circuitrare
How to diagnose
- Read all stored codes and freeze frame data, noting whether B00E0 is current or history and whether other SRS codes are present
- Check for recent work on the car, such as seat removal, trim removal, a crash repair or water leaks
- Visually inspect the third row left seat belt assembly, wiring route and connectors for damage, pinching, corrosion or loose fit, following the manufacturer's SRS safety procedure
- Follow the manufacturer's procedure to isolate the battery and let the system discharge before disconnecting any SRS connector
- Check the connectors for bent or pushed-back pins, corrosion and a locked, fully seated fit
- Test the circuit and pretensioner using the manufacturer's specified method only; never apply a test light or standard multimeter probes to a squib
- Check the wiring for continuity and shorts between the module and the pretensioner, and look for a damaged shorting clip or a connector fault
- Clear the code after repair and confirm it does not return after cycling the ignition and operating the seats
How to fix
- Repair or replace damaged wiring, using the manufacturer's approved method for SRS circuits
- Clean, repair or replace faulty connectors, and make sure they are fully seated and locked
- Replace the third row left seat belt pretensioner assembly if it is faulty or has been deployed
- Replace any components damaged in a previous crash, as specified by the manufacturer
- Replace the restraint control module only if testing confirms it is faulty, and complete any required setup afterwards
Can I keep driving?
The car may drive normally, but the third row left pretensioner may not work in a crash, so it is a safety risk. Avoid carrying anyone in that seat and get it inspected promptly.
