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 55 of the engine control module and tested for 3 seconds when the ignition is switched ON.

A combination of light engine load and high engine revs when the car is being driven will cause the lamp to light up. This does not apply when 5th gear is engaged.

The lamp lights up regardless of engine load when engine speed approaches 6000 rpm.

The ECM calculates the gear position on the basis of engine speed and vehicle speed.
