Winter Indicator Lamp

WINTER Indicator Lamp












To make starting easier on slippery road surfaces, the TCM transmission is equipped with a winter mode, i.e. the car starts in 3rd gear when the winter button (W) on the selector lever is pressed.

The lamp is supplied with current in the main instrument unit and grounded by the main instrument unit control module. TCM continuously sends bus information WINTER 0N1 unit ON/OFF.

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

The indicator lamp goes out under the following conditions:
- The winter button is pressed again.
- The transmission is in Limp-home mode.
- The ignition is turned off and on again.
- The transmission fluid temperature is above 140 °C.
