KICK DOWN SWITCH CIRCUIT
CIRCUIT DESCRIPTION
The kick±down switch is turned ON when the accelerator pedal is depressed to the full throttle and sends
signals to 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.

STOP LIGHT SWITCH SIGNAL CIRCUIT
CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling while driving in lock±up condition, when
brakes are suddenly applied.
When the brake pedal is depressed, this switch sends a signals to the ECM. Then the ECM cancels the op-
eration of the lock±up clutch while braking is in progress.

PARK/NEUTRAL POSITION SWITCH CIRCUIT
CIRCUIT DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.
The ECM receives signals (REVERSE and DRIVE) from the park/neutral position switch.
