2. OPERATION PRINCIPLE
2.1 PREHEATING
196WA01B
When the ignition key is turned to the “ON” position, the
preheat controller and timer controller are supplied with
power. The preheat controller turns on the preheat lamp
on the instrument panel for up to 8 seconds and oper-
ates the preheat relay for up to 9 seconds for
preheating. However, the preheat lamp and preheat-
ing operation stop when the ignition key is turned to
the “START” position. When the ignition key is back to
the “ON” position after starting the engine, the preheat
controller operates the preheat relay again for 20 sec-
onds for after heating. This is to optimize fuel combus-
tion in the engine after starting.
If necessary, it is possible to preheat the glow plug
temporarily (manually) by setting the ignition key to the
“GL” position between the “ON” and “ST” positions. The
preheat lamp on the instrument panel does not come
on in case of after and manual heating.
