The car's computer is saying that there's too much electricity going to the part of the brakes that helps stop the car safely.
The ABS (Anti-lock Braking System) pump motor supply voltage is higher than expected, indicating a potential electrical issue in the circuit.
This code indicates that the voltage level in the ABS pump motor supply circuit B is higher than the predetermined threshold set by the manufacturer. This could be due to a short circuit, faulty wiring, or a defective ABS control module.

Check with the vehicle manufacturer for specific warranty coverage on ABS components.
This code has been reported in vehicles with ABS systems that have experienced electrical issues due to aging or environmental factors.
Moderate – It is important to address this issue to ensure proper braking performance.
Driving with a malfunctioning ABS system can affect braking performance and increase the risk of an accident.
• Vehicle stationary with engine running
• Use of a multimeter to test voltage levels
The ABS pump motor is typically located near the brake master cylinder in the engine bay.
