SHIFT UP Indicator Lamp

SHIFT UP indicator lamp

SHIFT UP:

Schematic:

To achieve low fuel consumption, the SHIFT-UP indicator lamp on the main instrument unit lights up when a higher gear should be engaged.

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

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

When the shift has been made, the engine control module changes the status of the information to SHIFT UP OFF and the lamp goes out.

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