OBD code B1287 means Servo Motor Potentiometer Right Circuit Failure.

This code is triggered by an issue with the servo motor potentiometer on the right side of the vehicle.

The servo motor potentiometer is part of the HVAC (Heating, Ventilation, and Air Conditioning) system and is responsible for controlling the position of the blend door or mode door.

When this component fails or malfunctions, it can result in improper air distribution or temperature control inside the vehicle.

Code B1287 indicates a low battery voltage condition in the audio control module.

OBDII code B1287 indicates a problem with the servo motor potentiometer circuit in the HVAC system.

To diagnose, use a voltmeter to check for voltage at the servo motor connector.

Ensure wiring and connectors are intact, looking for damage or corrosion.

Test the servo motor’s resistance with the voltmeter to verify its functionality.

A scan tool can help monitor HVAC data and confirm proper servo motor operation.

If necessary, replace the servo motor or repair any damaged wiring.

Remember to clear the code after repairs are made.
