When theignition keyisinserted intothekey
cylinder, theengine control module turnsonthe
relay andthe"high-level" electriccurrentflows
through theglow plugs andheats themup

TROUBLEDIAGNOSES
Quick-glow System(Cont'd)
DESCRIPTION
Engine coolant temperature sensor(ECTS)

The engine coolant temperature sensordetects enginecoolant
temperature andtransmits asignal tothe ECM.
Electrical resistance ofthe thermistor decreases inresponse to
the temperature rise.

Key-in switch

The key-in switch isbuilt intothekey cylinder. TheECM detects
the key position andcontrols thekey-in glowsystem.
