The main instrument unit incorporates a CRUISE indicator lamp that lights up when Cruise Control is engaged.

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 CRUISE Lamp, unit ON/OFF.

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

After disengaging cruise control, the engine control module will change the status of the information to CRUISE Lamp OFF and the lamp will go out.
