WIRING SYSTEM 8DÐ111
QOS-III (4JG2)
General Description
The circuit consists of the starter switch, QOS-III
control unit, glow relay, charge relay, fuel cut
solenoid, dropping resistor, thermo sensor, glow
indicator light (meter), glow plug and car speed
sensor. The engine coolant temperature at the time
of the engine start-up is sensed by the thermo
sensor to change the glow time so that the optimum
starting conditions can always be obtained.
The idling speed just after the engine start-up can
also be placed in the most suitable conditions in
accordance with the coolant temperature by the
operation of the delay timer.The indicator timer is activated upon the starter
switch turned to the ON position, and the indicator
light comes on for as much time as suitable for the
engine coolant temperature at the time of the
engine start-up.
