What it means
The restraint control module monitors driver seat occupant position sensor E as part of the occupant position system. It sets this code when it detects a fault in that sensor or its circuit; the title does not specify the failure mode.
At a glance
- Usually lights the airbag (SRS) or body-system warning light
How it works
Driver seat occupant position sensor E is a distinct input monitored by the restraint control module as it assesses the driver's position relative to the airbag. B00BB is stored when the module detects a fault involving sensor E or its circuit; it does not by itself identify the failed part or failure type.
Common causes
Most likely first.
- Faulty driver seat occupant position sensor E
- Damaged wiring or connector at the sensor
- Obstruction or damage affecting sensor readings
- 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
- Use a scan tool to read restraint-module codes, freeze-frame data, and sensor E live status, noting whether the code returns after clearing under the manufacturer's procedure.
- Check the driver seat area for objects, damage, or upholstery changes that could interfere with sensor E.
- Inspect sensor E's wiring and connector for pin damage, loose connections, chafing, or moisture, taking restraint-system precautions.
- If permitted by the manufacturer's procedure, monitor sensor E data as the driver seat is moved normally and look for signal dropouts or inconsistent readings.
- Test sensor E and its wiring against the manufacturer's specification, and consider the restraint control module only after those components pass.
Common fixes
- Remove any obstruction affecting driver seat sensor E.
- Repair damaged wiring or clean and secure a faulty sensor E connector as appropriate.
- Replace sensor E if it fails the manufacturer's test procedure.
- Repair or replace the restraint control module only after confirming sensor E and its circuit are sound.
Can I keep driving?
Treat a restraint-system warning as a possible impairment of airbag operation and arrange diagnosis promptly. Avoid disturbing wiring beneath or around the driver seat.
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.
