Shift Light: Description and Operation

The lamp is situated in the main instrument display panel and supplied with current from the +15 circuit. It is controlled from pin 64 of the control module and tested for 3 seconds each time the ignition is switched on. A combination of light engine load and high engine rpm will cause the lamp to light up when the car is being driven. This does not apply to 5th gear.

When engine speed approaches 6000 rpm the lamp will light up regardless of engine load.

The control module calculates the gear position on the basis of engine rpm and vehicle speed.
