Throttle actuator control system
Description
The throttle actuator is operated by the ecm, and opens and closes the
throttle valve using gears. The
opening angle of the throttle valve is detected by the throttle position (tp)
sensor, which is mounted on
the throttle body. The tp sensor provides feedback to the ecm in ord ...
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 ...
