Light Reminder System; Key Reminder Buzzer System; D6 Door Courtesy Sw Lh; D7 Door Courtesy Sw Rh - Toyota MR2 2000 Manual

SYSTEM OUTLINE

1. LIGHT REMINDER SYSTEM

When the ignition SW is OFF and the driver's side door or passenger's side door is opened (Door courtesy SW ON) and the
light control SW is at TAIL or HEAD position, the light reminder buzzer comes ON.

2. KEY REMINDER BUZZER SYSTEM

If the driver door is opened with the ignition SW set at the ACC or OFF position and the ignition key remained inserted into
the key cylinder (The unlock warning SW is on), the signal from the unlock warning SW is input to TERMINAL KSW of the
body ECU and the signal from the door courtesy SW LH is input to TERMINAL DCTY of body ECU. As a result, through
communication control of the body ECU etc. the buzzer in the combination meter goes on to warn the driver that the ignition
key is still inserted.
