NOTICE:
SExercise extreme care not to damage the glow plug
pipes. Damaging them could cause an open circuit, or
shorten the life of the glow plugs.
SKeep the glow plug free of oil and fuel while cleaning.
SWipe any oil off the terminal and Bakelite washer with
a clean−dry cloth during inspection.
SDo not apply more than11V to the glow plug as it
could cause an open circuit.
(c) Reconnect the glow plug wire.

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.

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.

INSPECTION PROCEDURE
1 DRIVING TEST
(a) Start the engine.
(b) Turn the ECT SNOW switch ”OFF” (Normal drive mode).
(c) Confirm vehicle response by driving from a parked position to fully depressing the accelerator pedal.
(d) Turn the ECT SNOW switch ”ON” and perform the same check as (c).
Confirm that there is a difference between ECT SNOW switch ”ON” and ”OFF”.
HINT:
S Driving test should be done on a paved road (a nonskid road).
S Make sure not to use the TRAC system when testing a vehicle equipped with one.
OK:
There is a difference in acceleration between ”ON” and ”OFF”.

TRANSMISSION CONTROL SWITCH CIRCUIT
CIRCUIT DESCRIPTION
When moving the shift lever into the S position using the transmission control switch, it is possible to switch
the shift range position between ”1” (first range) and ”5” (fifth range).
Shifting up ”+” once raises one shift range position, and shifting down ”−” lowers one shift range position.
