Description
This solenoid is turned on in accordance with signals from the skid control ecu and controls the pressure on the wheel cylinders to control the braking force.
The solenoid and solenoid relay are built into the abs and traction actuator.
Hint:
Dtcs c0226/21, c0236/22, c0246/23, c0256/24 and c1225/25: the skid control ecu begins to detect these dtcs when the vehicle speed exceeds 6 km/h (4 mph).

Hint:
The dtcs may be stored due to a malfunction in the connector terminal.
Replace abs and traction actuator
Description
If a dtc related to the motor line is stored, the vsc fail (fail-safe) relay cuts off the power supply to the vsc mtr relay and performs the fail-safe operation.
While the abs, trc, vsc, or ba is operating, the skid control ecu turns the vsc fail relay on and activates the pump motor in the abs and traction actuator.
These dtcs may be stored if the motor relay (+bm) voltage becomes lower than the dtc detecting condition due to insufficient output from the battery or alternator.
Hint:
Dtcs c0273/13, c0274/14 and c1361/91: the skid control ecu begins to detect these dtcs when the vehicle speed exceeds 6 km/h (4 mph).

Power supply relay failure
Description
If the power steering ecu detects these dtcs, it shuts off the motor relay
circuit (built into the power
steering ecu) and stops power assist.
Inspection procedure
Reconfirm dtc
Check for dtc.
Ok:
dtc is not output.
Replace power steering ecu ...
