DTC C146E: Open Circuit in ABS Solenoid Relay Circuit; DTC C146F: Short Circuit in ABS Solenoid Relay Circuit [11/2017 - 03/2019]: 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 engine switch is turned on (IG), 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 Circuit in ABS Solenoid Relay Circuit	Either of the following is detected: When the 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. When the 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 Circuit in ABS Solenoid Relay Circuit	Immediately after engine switch turned on (IG) and solenoid relay is OFF, relay contact is ON continuously for 4.5 seconds or more.	Skid control ECU (brake actuator assembly)
