*1: Turns on when two or more wheels are faulty.
*2: Stays on until the vehicle speed reaches 10 km/
h when the ignition switch is turned to ON next time.
*3: This diagnostic trouble code is not set with the
vehicle speed of 20 km/h or less.
*4: AWD only
DIAGNOSTIC TROUBLE CODE READING
METHOD
There are 70 diagnosis items (FWD) or 73 diagnosis
items (AWD). The diagnostic trouble code can be
checked using the M.U.T.-III scan tool.
HOW TO ERASE DIAGNOSTIC TROUBLE CODE
MEMORY
Diagnostic trouble code can be erased using the
M.U.T.-III scan tool.
Data list output
The following items input to ASC-ECU can be read
using scan tool.

ACTUATOR TEST
Using the M.U.T.-III scan tool, the actuators can be
forcibly operated. The M.U.T.-III scan tool can also
bleed the active stability control system.
When ASC-ECU is disabled, the actuator test cannot
be performed.
016'
Scan tool uses the ABS data list.
For the actuator test specification, refer to
Workshop Manual.
CALIBRATION
After the G and yaw rate sensor and steering wheel
sensor have been replaced with new ones, calibration
must be performed using the M.U.T.-III scan tool*.
016'
The M.U.T.-III scan tool uses the ABS data list.
*: For calibration, refer to Workshop Manual.
DESCRIPTION OF CONSTRUCTION AND OPERATION
M23506100006USA0000010000
ACTIVE SKID CONTROL OPERATION
ASC-ECU receives various kinds of information from
the engine ECU, AWD-ECU, ETACS-ECU, A/T-ECU,
steering wheel sensor, G and yaw rate sensor, and
wheel speed sensor. When ECU determines the
vehicle runs in the spinning out or plowing out
direction based on the signal sent from these sensors,
ASC-ECU drives each valve and pump motor and
controls the braking force to be applied to the wheels.
When the system increases the fluid pressure
automatically, it closes the cut valve to shut off the
pressure line to the suction valve, and drives the pump
motor. For example, when the vehicle runs in the
plowing out direction while turning to the right, ASC-
ECU supplies the brake fluid from the pump to the
front left wheel to apply the braking force on it.
