INSPECTION INTERIOR TEMPERATURE SENSOR CHECK When the resistance between the sensor terminals is measured under two or more
temperature conditions, the resistance should approximately satisfy the illustrated
values.

ACTUATOR HYDRAULIC UNIT The hydraulic unit includes a cut valve, suction valve and pressure switch for the
active skid control additionally, compared with the conventional hydraulic unit for
the ABS control. TRACTION CONTROL/ACTIVE SKID CONTROL SYSTEM OPERATION INDICATOR LIGHT AND TRACTION
CONTROL SYSTEM OFF INDICATOR LIGHT The Traction control/Active skid control system operation indicator light and
Traction control system OFF indicator light illuminate or flash under the conditions
below to inform the driver. TRACTION CONTROL/ACTIVE SKID CONTROL SYSTEM INDICATOR LIGHT
When the active skid control is active, the light flashes. When the traction control is active, the light flashes. When sensors related to traction control and active skid control are not
initialized, the li
ght flashes at a fre
quenc
y of once
per second.
NOTE:
The Traction control will activate when the system has
not been disabled by the traction control OFF switch,
and the vehicle speed has reached 4 - 9 mph (6 - 14
km/h). The traction control will deactivate when the front wheel
speed (both wheels) have decreased to 1 - 4 mph (2 - 6
km/h) for one second or more (four seconds or more if
the system is controlling the engine output). The Active skid control will be activated when the
vehicle speed exceeds 12 mph (20 km/h). The Active skid control will deactivate when the vehicle
speed has decreased to 9 mph (15 km/h) or lower.
NOTE: For the internal hydraulic circuit of the hydraulic unit, refer
to ACTIVE SKID CONTROL SYSTEM OPERATION

The ECU incorporates the ABS-ECU, active skid control-ECU, and traction
control-ECU. The integral design allows joint operation of the TCL/ASC-ECU with
the ABS and coordinated control of the driving force and braking force. SYSTEM CONFIGURATION The Traction Control and Active Skid Control (TCL/ASC) System is a system that
adds a yaw rate sensor, a steering wheel sensor and master cylinder pressure sensor
(incorporated in hydraulic unit) to the ABS system. OVERVIEW OF CONTROL The TCL/ASC-ECU detects vehicle movement based on information from various
sensors and calculates a model of ideal vehicle movement. After comparing actual
and ideal movements, it acts to bring the actual vehicle movement closer to the
ideal model by controlling specific wheel brake force and governing engine output.
It restrains under-steering and over-steering through a corrective yaw moment, as
explained on the following pages. EXAMPLE OF ACTIVE SKID CONTROL OPERATION The Active Skid Control manages the vehicle attitude by creating a yaw moment
from altering the balance between the cornering force and each wheel's braking
mechanism.
For example, on a slippery surface, if the vehicle tends to be under-steered contrary
to the driver's intention, a yaw moment (a rotational moment) is created to restrain
the under-steering by increasing the rear-inside braking force. On the other hand,
when the vehicle tends to be over-steered, a yaw moment (a restorative moment) is
created to restrain the over-steering by increasing the front-outside braking force.
Furthermore, when it is determined that the vehicle is over-speeding, safe and stable
cornerin
g is enabled b

2. Turn the ignition switch to the "ON" position.
3. Check whether DTC C1200, C1205, C1210 or C1215 have been set.
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1200, C1205, C1210 or C1215 set?
YES: Carry out diagnosis relevant to DTC C1200, C1205, C1210 or
C1215 (Refer to ANTI
-LOCK BRAKING SYSTEM (ABS)
DIAGNOSIS
).
NO: Go to Step 4.
STEP 4. Check the installation condition of the ABS sensors.
For the ABS sensor, which the DTC code indicates, check whether the sensor
or its mounting bolts are loosened.
DTC C1201 is set: Front right ABS sensor DTC C1206 is set: Front left ABS sensor DTC C1211 is set: Rear right ABS sensor DTC C1216 is set: Rear left ABS sensor
Q: Is the ABS sensor installed correctly?
YES: Go to Step 5.
NO: Reinstall the ABS sensor correctly. Then go to Step 16.
STEP 5. Check the ABS sensor after it is removed from the vehicle.
Check the ABS sensor, which the DTC code indicates (Refer to
INSPECTION
, ).
DTC C1201 is set: Front right ABS sensor DTC C1206 is set: Front left ABS sensor DTC C1211 is set: Rear right ABS sensor DTC C1216 is set: Rear left ABS sensor
