Circuit Diagram
Inspection & Maintenance Procedure (for MSE)
1. While the ignition switch is in 'OFF' position, remove thewiring connectors (1 and 15) from ignition coil and measure the primary resistance between terminal No.1 and No.15.
2. During engine cranking, measure primary voltage (T1/1) between ECU terminal No. 71 and No. 69.
Notice If out of specified value, replace the ignition coil.
Specified Value
0.9 - 1.6 (20 °C)
Specified Value 200 - 350 V
Notice
Measure remaining cables.
- T1/2 : No. 72 and 69.
- T1/3 : No. 70 and 69.
If out of specified value, check ignition cable and ECU.
3. Using a multi-tester, measure the secondary coil resistance between 5a and 5b.
Specified Value 6 - 8.5 k

Inspection & Maintenance (for E2.3 MSE)
1. Measure the primary resistance between the cable terminals1 and 15 after removing the ignition cable wiring connector
(1 and 15) with ignition switch OFF. Notice Replace the ignition coil if out of the specified resistance.
T1/2 : between No.71 and No.69
Notice Check the ignition cable and the ECU if out of the
specified value.
3. Measure the secondary cable resistance between the ignition coil 5a and 5b using a multimeter.
2. Measure the primary voltage(T1/1) between the ECU
terminals No.72 and No.69 during the engine cranking (starter motor activated).
Specified Value 6 - 8.5 K
Specified Value0.9 - 1.6
Specified Value 200 - 350 V

OM600 ENGINE ELECTRICAL 1E3-3
1. Preheating time - control relay.Control relay functions as followings :
Switching of preheating current.
Indication of preheating finish.
Control of preheating sequence.
Indication 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 Current 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.
Temperature 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.
