12.CHECKING OF MIL(MALFUNCTION INDICATOR LAMP)CIRCUIT
Fault code number is displayed by MIL
CHECKING CIRCUIT
CHECK PROCEDURE
1) Turn off ignition key.
2) Check the ESS coupler is loose, or bad.
If there is no problem.
3) Turn on the ignition key.
4) Check the MIL on for 3 seconds when turn on the ignition key at the same time.
If there is no lighting, check the Lamp.
But If the Lamp is working for 3 second,
5) Measure the MIL voltage of wire harness to check ECU.
Measuring terminal :
B electric wire ~
EARTH => Output Voltage: battery voltage
Measuring terminal :
ECU No.24(L/B :BLUE /BLACK) ~
EARTH => Output voltage:
battery voltage
Remarks : Measuring unit of voltage : Voltage[V]
If the measured voltage is normal,
Check the ‘L/B’ electric wire, ‘B’ electric wire, ‘Br/L’ electric wire to see if they have been broken or
have short- circuited if there is a bad contact of terminal No. 24 of ECU coupler.
If there is no problem in wires, ECU has is broken.
Replace the ECU with new one, and rechecks it.
If the measured voltage is abnormal,
Check the ‘L/B’ electric wire, ‘B’ electric wire, ‘Br/L’ electric wire to see if they have been
broken or have short- circuited.
6) After fault repaired, To erase the memorized fault code in the ECU is refer to how to remove the fault code(5-10)
