The INFO DISPL lamp comes on when a message is displayed on SID. The lamp is powered with +15 from the main instrument unit and grounded by the main instrument unit control module. SID sends continuous bus information INFO DISPL, unit ON/OFF.

On receiving INFO DISPL ON, the control module grounds the output for the lamp which then lights up.
