This system is controlled by the main body ecu. The main body ecu outputs signals to each door lock motor.
The door lock control system in the vehicle has the following functions:
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 ...
Engine immobiliser system malfunction
Description
This dtc is output when one of the following occurs: 1) the ecm detects
errors in its own
communications with the transponder key ecu; 2) the ecm detects errors in the
communication lines; or
3) the ecu communication id between the transponder key ecu and ecm is different
an ...
On-vehicle inspection
Check throttle body
Check the throttle control motor operating sounds.
Turn the ignition switch on.
When pressing the accelerator pedal, check
the operating sound of the running motor. Make
sure that no friction noises emit from the motor.
If friction noise exists, replace t ...
