DTC C1365/54 Accumulator Pressure Sensor Malfunction: Description
The accumulator pressure sensor is built into the brake actuator.
The skid control ECU detects the accumulator pressure based on the data sent from the accumulator pressure sensor, and then runs and stops the pump motor by operating the motor relay.
