Code C146C Lexus Description

The Motor Relay and motor fail-safe relay are built into the Brake Actuator Assembly. During ABS, TRAC, VSC, brake hold, or brake assist operation, the Skid Control ECU (Brake Actuator Assembly) turns on the motor relay to run the pump motor in the Brake Actuator Assembly. When a motor system Diagnostic Trouble Code (DTC) is stored, the motor fail-safe relay cuts the power source supply to the motor relay for fail-safe operation.
This DTC may be stored when the voltage to the motor relay power source is lower than the DTC detection condition due to low output from the battery or alternator.
