IGNITION SIGNAL
Component Inspection (Ignition Coil with Power Transistor)
INFOID:0000000001693442
1.
CHECK IGNITION COIL WITH POWER TRANSISTOR-I
1.
Turn ignition switch OFF.
2.
Disconnect ignition coil harness connector.
3.
Check resistance between ignition coil terminals as follows.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Replace malfunctioning ignition coil with power transistor.
2.
CHECK IGNITION COIL WITH POWER TRANSISTOR-II
CAUTION:
Do the following procedure in the place where ventilation is good without the combustible.
1.
Turn ignition switch OFF.
2.
Reconnect all harness connectors disconnected.
3.
Remove fuel pump fuse in IPDM E/R to release fuel pressure.
NOTE:
Do not use CONSULT-III to release fuel pressure, or fuel pressure applies again during the following pro-
cedure.
4.
Start engine.
5.
After engine stalls, crank it two or three times to release all fuel pressure.
6.
Turn ignition switch OFF.
7.
Remove all ignition coil harness connectors to avoid the electrical discharge from the ignition coils.
8.
Remove ignition coil and spark plug of the cylinder to be checked.
9.
Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
10. Connect spark plug and harness connector to ignition coil.
11. Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 -
0.66 in) between the edge of the spark plug and grounded metal
portion as shown in the figure.
12. Crank engine for about three seconds, and check whether spark
is generated between the spark plug and the grounded metal
portion.
CAUTION:
• Do not approach to the spark plug and the ignition coil
within 50 cm (19.7 in). Be careful not to get an electrical
shock while checking, because the electrical discharge
voltage becomes 20kV or more.
• It might cause to damage the ignition coil if the gap of more than 17 mm 0.66 in) is taken.
NOTE:
When the gap is less than 13 mm (0.52 in), the spark might be generated even if the coil is mal-
functioning.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Replace malfunctioning ignition coil with power transistor.
