DTC C146E: Open in ABS Solenoid Relay Circuit; DTC C146F: Short in ABS Solenoid Relay Circuit [11/2016 - ]: Description

The ABS solenoid relay supplies power to the ABS solenoid and TRAC solenoid.

The solenoid relay is turned on 1.5 seconds after the ignition switch is turned to ON, and is turned off if an open or short in the solenoid is detected by self diagnosis performed when the vehicle starts running.

The ABS solenoid relay is housed in the skid control ECU in the brake actuator assembly.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
C146E	Open in ABS Solenoid Relay Circuit	Either of the following is detected: When voltage at terminal +BS is 9.5 V or higher and solenoid relay is ON, relay contact is OFF continuously for 0.22 seconds or more (except restart due to stop and start control*). When solenoid relay is turned on and voltage at +BS terminal is below 9.5 V, relay contact does not turn on after 0.22 seconds or more.	Wire harness or connector Skid control ECU (brake actuator assembly)
C146F	Short in ABS Solenoid Relay Circuit	Immediately after the ignition switch is turned to ON, the ABS solenoid relay contact is closed for 4.5 seconds when the relay is turned off.	Wire harness or connector Skid control ECU (brake actuator assembly)
