KICK DOWN SWITCH CIRCUIT
CIRCUIT DESCRIPTION
The kick−down switch is turned ON when the accelerator pedal is fully depressed and a signal is sent to the
ECM.
When the kick−down switch is turned ON, the ECM controls gear shifting according to the programmed shift
diagrams.
If a short circuit develops in the kick−down switch, the ECM disregards the kick−down signals and controls
shifting at the normal shift points.

When the ECT SNOW switch is pushed, the switch contact is made and the ECT SNOW mode is selected.
To cancel the ECT SNOW mode, push the ECT SNOW switch once again. The ECT SNOW mode is automatical-
ly cancelledout when the ignition switch is turned ”OFF”.

PATTERN SELECT SWITCH CIRCUIT
CIRCUIT DESCRIPTION
Integration relay receives pattern select switch information, and sends it through the multiplex communica-
tion system to the ECM.
ECT SNOW is the system that operates the throttle motor to control engine output to reduce skidding of the
driving wheels, guarantee takeoff acceleration, driving straightness and turning stability.

DTC P0985 SHIFT SOLENOID ”E” CONTROL CIRCUIT
LOW (SHIFT SOLENOID VALVE SR)
DTC P0986 SHIFT SOLENOID ”E” CONTROL CIRCUIT HIGH (SHIFT SOLENOID VALVE SR)
CIRCUIT DESCRIPTION
Shifting from 1st to 5th is performed in combination with ”ON” and ”OFF” operation of the shift solenoid valves
SL1, SL2, SL3, S4 and SR which is controlled by the ECM. If an open or short circuit occurs in either of the
shift solenoid valves, the ECM controls the remaining normal shift solenoid valve to allow the vehicle to be
operated smoothly (Fail safe function).

S Shift solenoid valve SR
S ECM
MONITOR DESCRIPTION
The ECM commands gear shifts by turning the shift solenoid valves ”ON/OFF”. When there is an open or
short circuit in any shift solenoid valve circuit, the ECM detects the problem and illuminates the MIL and
stores the DTC. And the ECM performs the fail −safe function and turns the other shift solenoid valves in good
condition ”ON/OFF” (In case of an open or short circuit, the ECM stops sending current to the circuit.)
