What it means
Fault on the driver seat track position sensor — detects fore/aft seat position, used by the airbag controller to adapt deployment to seat distance from steering wheel.
At a glance
- Usually lights the airbag (SRS) or body-system warning light
How it works
The driver seat track position restraints sensor reports how far forward or rearward the seat is positioned, information the restraint controller can use when managing deployment. B00B5 indicates a fault associated with this track-position sensor or its circuit, without specifying the failure mode.
Common causes
Most likely first.
- Faulty driver seat track position sensor
- Damaged wiring or connector near the seat track
- Loose or corroded electrical connection
- 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
- Read restraint-module codes and available seat-position data, then record freeze-frame information before clearing the code.
- Move the driver seat through its normal travel and check whether the position reading changes smoothly or the fault appears at a particular position.
- Inspect the sensor and wiring along the driver seat track for impact damage, pinching, abrasion, or a connector pulled taut.
- With the restraint system powered down per the manufacturer's procedure, check the track-position sensor connector for looseness or corrosion.
- Test the sensor circuit and position signal using the manufacturer's diagnostic steps and specifications.
- If the sensor and wiring pass, check the restraint control module inputs and connections.
Common fixes
- Free or reposition wiring that is caught or stretched along the seat track.
- Reconnect and secure the track-position sensor connector.
- Repair damaged track-position sensor wiring or terminals.
- Replace the driver seat track position sensor if testing confirms failure.
- Repair or replace the restraint control module if diagnostics isolate the fault there.
Can I keep driving?
The restraint system may not know the driver seat's fore-aft position when managing airbag deployment. The car may still drive normally, but arrange prompt repair and avoid relying on normal airbag performance.
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.
