DTC C146E: Open Circuit in ABS Solenoid Relay Circuit; DTC C146F: Short Circuit in ABS Solenoid Relay Circuit [04/2018 - ]: Description

WARNING: This page is about a different variant/trim than selected.

The ABS solenoid relay built into the skid control ECU (brake booster with master cylinder assembly) supplies power to the holding solenoid and reduction solenoid.

The ABS solenoid relay is operated 1.5 seconds after the power switch is turned on (IG), and is turned off if an open or short in the ABS solenoid is detected during self-diagnosis when the vehicle starts driving.
