Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pinpoint Test MB: Driver Seat Track Sensor: Notes
Refer to appropriate Supplemental Restraint System in OEM Wiring Diagrams article, for schematic and connector information.
Normal Operation and Fault Conditions
The RCM continuously monitors the driver seat track position sensor circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
- Faulted driver seat track position sensor
If a fault is detected, the RCM stores DTC B00B5:11, B00B5:12, B00B5:13 or B00B5:1D in memory and sends a message to the IPC to illuminate the airbag warning indicator.
PPT M RCM DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B00B5:11 | Driver Seat Track Position Restraints Sensor: Circuit Short to Ground | Sets when the RCM senses a short to ground from the driver seat position sensor circuit. |
| B00B5:12 | Driver Seat Track Position Restraints Sensor: Circuit Short to Battery | Sets when the RCM senses a short to voltage from the driver seat position sensor circuit. |
| B00B5:13 | Driver Seat Track Position Restraints Sensor: Circuit Open | Sets when the RCM senses an open from either driver seat position sensor circuit. An open driver seat track position sensor ground circuit also sets this fault. |
| B00B5:1D | Driver Seat Track Position Restraints Sensor: Circuit Current Out of Range | Sets when the RCM senses current out of an acceptable range from the driver seat position sensor circuit. |
Possible Causes
- Wiring, terminals or connectors
- Driver seat track position sensor
- RCM
Visual Inspection and Diagnostic Pre-checks
- Inspect for a damaged driver seat track position sensor.
- Inspect for damaged wiring harness(es).
- Inspect for loose or damaged connectors.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
