Code B1B8C RAM Description
The B1B8C diagnostic trouble code (DTC) refers to the driver seat track position sensor circuit performance. This code is typically found in vehicles equipped with power adjustable seats, where the seat position is controlled electronically. The seat track position sensor is responsible for monitoring the position of the driver's seat and sending this information to the vehicle's computer system. This allows the system to adjust the seat position according to the driver's preferences.
Common Causes of B1B8C RAM
- Faulty seat track position sensor
- Wiring issues in the circuit
- Problems with the vehicle's computer system
- Loose or damaged connections in the seat track position sensor circuit
- Corrosion or damage to the sensor components
Symptoms of B1B8C RAM
- Erratic or non-responsive seat movements
- Inability to adjust the seat position
- Warning lights related to the power seat system on the dashboard
- Uncomfortable seating position while driving
How to Fix B1B8C RAM
- Begin by conducting a thorough inspection of the seat track position sensor and its wiring to identify any visible signs of damage or wear.
- Use a multimeter to test the sensor's resistance and voltage output to determine if it is functioning within the manufacturer's specifications.
- Check for loose or damaged connections in the circuit and repair or replace them as needed.
- If the sensor is found to be faulty, replace it with a new one that is compatible with the vehicle's make and model.
- Clear the DTC from the vehicle's computer system using a diagnostic scan tool and test the power seat functionality to ensure that the issue has been resolved.
Cost to Fix B1B8C RAM

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
Frequently Asked Questions about B1B8C RAM Code
1. What does the OBDII code B1B8C mean?
