EXAMPLE OF OPERATION OF TRACTION CONTROL The Traction Control prevents drive force loss during slipping of the drive wheels
by automatically applying the brakes and sending engine torque reduction signal to
the PCM when the drive wheels slip or when driving on partly low-friction
surfaces. FAIL-SAFE AND DIAGNOSTIC FUNCTIONS The TCL/ASC-ECU regularly monitors input and out put signals. If an error is
detected in the system, the ECU sends a fail signal and the TCL/ASC indicator light
is illuminated or blinks. Various controls are processed depending on the cause of
malfunction as shown below. When the ABS system fails, the TCL/ASC system is
also suspended. However, when the TCL/ASC system fails, no other systems are
suspended. The appropriate indicator lights are illuminated/flashed.
The TCL/ASC-ECU includes the following functions to make system inspection
easier.
Diagnostic trouble code Display Data list Actuator test
All of the above operations can be carried out using scan tool MB991958.
ACTIVE SKID CONTROL SYSTEM OPERATION The TCL/ASC-ECU receives information from the PCM, the steering sensor, the G
and yaw-rate sensor and the wheel speed sensor. If the ECU determines that the
vehicle is tending to oversteer or understeer, it sends signals to the active skid
control system valves and the ABS solenoid valves to increase the fluid pressure to
the wheels.
The system closes the cut valve to shut the fluid channel to the suction valve, and
activates the
pum
p motor. The brake fluid, which is

unit reservoir, will be supplied to the front left wheel during oversteering or the rear
right wheel during understeering when the vehicle is at right turn. Furthermore, the
system also controls the engine if the accelerator pedal is depressed excessively. DURING NORMAL BRAKING Fig. 11: During Normal Braking Diagram

The brake fluid flows from the master cylinder to the cut valve and the inlet valve
to supply fluid pressure to the relevant wheels.
