Other materials:
Solenoid circuit
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, c02 ...
Downhill assist control operation switch (test mode dtc)
Description
The downhill assist control switch is connected to the skid control ecu in
the abs and traction
actuator.
Dtc c1379/74 can be detected when the downhill assist control switch sends the
downhill assist control
switch signal or test mode ends. Dtc c1379/74 is output only in t ...
Brake pedal load sensing switch
Description
The brake pedal load sensing switch is turned on when the brake pedal is
depressed with force exceeding
a predetermined level.
The skid control ecu detects if the brake pedal is depressed or not via this
circuit.
