OVERDRIVE CONTROL SWITCH
• Check continuity between A/T shift selector harness connector ter- minals.
TRANSMISSION RANGE SWITCH
1. Check continuity between transmission range switch harness connector terminals.
2. If NG, check again with control cable (2) disconnected from manual shaft (3) of A/T assembly. Refer to step 1.
(1): Lock nut
3. If OK on step 2, adjust control cable (2). Refer to AT-217,
"Adjustment of A/T Position".
4. If NG on step 2, remove transmission range switch from A/T assembly and check continuity of transmission range switch ter-
minals. Refer to step 1.
5. If OK on step 4, adjust transmission range switch. Refer to AT-
225, "Transmission Range Switch".
6. If NG on step 4, replace transmission range switch. Refer to AT-

• Closed throttle position signal and wide open throttle position sig- nal
ECM judges throttle opening based on a signal from accelerator
pedal position sensor, and sends the signal via CAN communica-
tion to the TCM.
DIAGNOSTIC PROCEDURE
NOTE:
The diagnostic procedure includes inspection for the tr ansmission range stitch, overdrive control switch,
closed throttle position signal and wide open throttle position signal circuit. Refer to AT-171

SYSTEM DESCRIPTION
TCS Function
INFOID:0000000005612145
• Spinning of the drive wheels is detected by the A BS/TCS/VDC control unit using inputs from the wheel
speed sensors. If wheel spin occurs, the drive wheel right and left brake fluid pressure control and engine
fuel cut are conducted while the throttle value is restricted to reduce the engine torque and decrease the
amount of wheel spin. In addition, the throttle openi ng is controlled to achieve the optimum engine torque.
• Depending on road condition, the vehicle may have a sluggish feel. This is normal, because optimum trac- tion has the highest priority during TCS operation.
• TCS may be activated during sudden vehicle acceleration, wide open throttle acceleration, sudden transmis- sion shifts or when the vehicle is driven on a road with a varying surface friction coefficient.
• The SLIP indicator lamp flashes to inform the driver of TCS operation.
VDC FunctionINFOID:0000000005612146
• In addition to the ABS/TCS function, the driver steering amount and brake operation amount are detected
from the steering angle sensor, and the vehicle's drivi ng status (amount of under steering/over steering) is
determined using inputs from the yaw rate/side/decel G sensor, wheel speed sensors, etc. and this informa-
tion is used to improve vehicle stability by cont rolling the braking and engine torque application to the
wheels.
• The SLIP indicator lamp flashes to inform the driver of VDC operation.
• During VDC operation, the vehicle body and brake pedal may vibrate lightly and a mechanical noise may be
heard. This is normal.
• The ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp may turn on when the vehicle is
subject to strong shaking or large vibration, such as when the vehicle is on a turn table or a ship while the
engine is running or steep slope. In this case, rest art the engine on a normal road and if the ABS warning
lamp, VDC OFF indicator lamp and SLIP indicator lamp turn off, there is no problem.
Wheel SensorsINFOID:0000000005612147
The front sensor units consist of a gear-shaped sensor rotor and a
sensor element. The element contains a magnet around which a coil
is wound. The front wheel sensors are installed on the front of the
wheel knuckles. As the wheel rotates, the sensor generates a
square-wave signal. The frequency in creases as the wheel speed
increases.
The rear sensor units consist of w heel hubs with a series of internal
magnets and a sensor element. The rear wheel sensors are installed
on the inner side of the wheel knuckles. As the wheel rotates, the
sensor generates a square-wave signal. The frequency increases as
the wheel speed increases.
Fail-Safe FunctionINFOID:0000000005612148
ABS/EBD SYSTEM
In case of an electrical malfunction with the ABS, t he ABS warning lamp, VDC OFF indicator lamp and SLIP
indicator lamp will turn on. In case of an electrical malfunction with the EBD system, the BRAKE warning lamp,
ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp will turn on.
