VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C146E

DTC Code DTC Name
C146E Open in ABS Solenoid Relay Circuit

DESCRIPTION

The ABS solenoid relay is built into the skid control ECU in the brake actuator assembly. The ABS solenoid relay supplies power to the ABS and TRC solenoids. The skid control ECU (brake actuator assembly) detects an ABS solenoid relay malfunction by performing a self check and relay operation check.
