Shift Up Indicator Lamp

SHIFT UP indicator lamp

SHIFT UP:

Schematic:

To achieve low fuel consumption, the SHIFT UP indicator lamp in the main instrument unit comes on when a higher gear should be engaged (certain markets).

The lamp is powered by the main instrument unit and is grounded internally by the main instrument unit. The engine control module sends continuous bus information SHIFT-UP, unit ON/OFF.

On receiving SHIFT-UP ON, the control module grounds the output for the lamp which then lights up.

If a higher gear is engaged, the engine control module will change the status of the information to SHIFT-UP OFF and the lamp will go out.

Diagnostics
The function has its own diagnostics in the sending system.
