Toyota Tacoma 2015-2018 Service Manual: SM Solenoid Circuit (C1225-C1228,C1468,C1469,C146A,C146B)

DESCRIPTION

The solenoid goes on when signals are received from the skid control ECU (master cylinder solenoid) and controls the pressure action on the wheel cylinders thus controlling the braking force.

DTC No.

1.

RECONFIRM DTC

HINT:

This DTCs are set when a problem is identified in the master cylinder solenoid.

The solenoid circuit is in the master cylinder solenoid.

Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if the DTCs are output before replacing the master cylinder solenoid.

(a) Clear the DTC (See page ). (b) Check if the same DTCs are detected. ).

(b) Check if the same DTCs are detected.
