Cruise indicator lamp: Notes
The main instrument unit incorporates a CRUISE indicator lamp that lights up when Cruise Control is 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 CRUISE lamp, unit ON/OFF.
On receiving CRUISE Lamp ON, the control module grounds the output of the lamp which then lights up.
If the cruise control is disconnected, the engine control module changes the status on information to CRUISE Lamp OFF and the lamp goes out.
