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.
