Details of the c0286 OBD Code
C0286 pertains to the ABS indicator lamp circuit being open or shorted.
OBD code C0286 means Brake Pedal Position Sensor Circuit Range/Performance.
This code is triggered by the Body Control Module (BCM) when it detects a circuit range or performance issue with the brake pedal position sensor.
The brake pedal position sensor is part of the brake pedal assembly and sends a signal to the BCM to indicate the position of the brake pedal.
If the sensor circuit is sending outofrange or erratic signals, the BCM will set code C0286. This code is related to the brake system and is crucial for proper brake operation and safety.
Mechanic’s Tech Notes
Code C0286 indicates a fault in the ABS actuator relay circuit.
OBDII code C0286 indicates an issue with the brake switch circuit.
To diagnose, use a voltmeter to check the brake switch for proper operation and voltage supply.
Inspect the wiring harness and connectors for any damage, corrosion, or loose connections.
Ensure the brake switch is functioning correctly and sending signals to the TCM.
Use a scan tool to monitor TCM response over the CAN network.
If necessary, reflash the TCM to address any communication errors.
Be thorough in your inspection of the brake switch system to pinpoint and resolve the root cause of the C0286 fault code.
