Coolant temperature gauge (MIU1)

Coolant temperature gauge (MIU 1)

The engine temperature sensor informs the ICE module of the temperature of the coolant.

This information is the passed on to the temperature gauge in the main instrument display panel as a 500 Hz PWM (Pulse Width Modulated) signal when the ignition switch is in the Start or Drive position.

Main instrument display panel 1 governs the ICE module's temperature display, i.e. the breakpoints in the temperature display are programmed directly in the ICE module.
