Q04246

The kick–down switch is turned on when the accelerator pedal
is depressed beyond the full throttle opening 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 dis-
regards the kick–down signals and controls shifting at the nor-
mal shift points.
