1. Preheating time - control relay.
Control relay functions as followings :
lSwitching of preheating current.
lIndication of preheating finish.
lControl of preheating sequence.
lIndication of fault.
2. Coolant temperature sensor.
Coolant temperature sensor senses coolant’s temperature
and signals it to the preheating relay continuously.
3. Glow plug
The glow plug parts are housing with M12 ´ 1.25 thread
and heating pin in housing. It is connected in a parallel circuit
with the specified voltage of 11.5V.
The heating element has a heating coil and a control coil
and they are connected in series.
1. Control Coil
2. Heater Coil
4. Current and temperature of glow plug
lCurrent of glow plug
While the preheating system operates, current of about
30A flows in each glow plug and temperature of heating
coil rises very fast.
Due to the rise of temperature, the resistance of control
coil increases therefore the current is controlled to
about 8~15A and that protects the glow plug from over-
heating.
lTemperature of glow plug
The temperature of the glow plug reaches up to 900°C
after about 9 seconds and up to 1,050°C after 30
seconds.

Preheating System Operation
1. Preheating before start.
Preheating time is different by coolant temperature and it is
on until the glow indicator light goes off.
2. Preheating after start.
Preheating continues for max. 60 seconds to rise in
characteristic of warming-up on engine after starting too.
3. Monitoring on glow plug.
Glow plugs are monitored by low current by the micro
processor in control relay respectively while running the
engine.
If glow indicator comes on after starting for about one minute,
it indicates on or several plugs are faulty.
Possible Cause
- One or several glow are faulty Problem
Glow indicator does not come on in preheating
time and comes on after starting the engine.
Glow indicator does not come on while
preheating and after starting engine.
Glow indicator does not come on and engine’s
starting is difficult or does not start at all.
Glow indicator comes on after starting for
about one minute.1

4- Faulty glow indicator
- Faulty circuit of glow indicator
- Faulty control relay
- Circuits short in one or several glow plugs
- Faulty preheating circuits
- Faulty control relay
- One or several glow plugs are faulty
