DESCRIPTION

The ABS solenoid relay and solenoid valves are built into the brake actuator assembly.

The front solenoid valve RH controls the brake fluid pressure of the front wheel cylinder RH of the vehicle.

When this DTC is stored, the fail-safe function operates and the ABS solenoid relay is turned off to prevent the solenoid valves from operating.
