1. While the ignition switch is in 'OFF' position, remove the
wiring 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 W (20°C)
Specified Value 200 - 350 V
Notice
lMeasure remaining cables.
- T1/2 : No. 72 and 69.
- T1/3 : No. 70 and 69.
lIf 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 kW

Removal & Installation Procedure
1. Remove the O-ring.
Check for damage and replace it if necessary.
2. Remove the injector bracket from the injector.
Installation Notice
Exactly seat the anti-twist lock into the square groove in
injector.
3. Separate the injector from the fuel distributor.
Inspection & Maintenance
Inspection of the Injector operation and spray pattern
1. Connect the contact box to the ECU.
2. Connect the shop made test plug to the injector and place
it into the tank.
3. Position the ignition switch to ON.
4. Connect the pin 63(+) and 69(-) of the contact box with a
test cable.
5. Check the injector spray pattern.
Notice
Replace the injector if the injector spray pattern is abnormal
or the fuel doesn't inject.
Injector Resistance Inspection
1. Remove the injector connector.
2. Measure the injector coil resistance using a resistance
tester.
Notice
Replace the injector if the measured values is out of the
specified values. Check the connector and wire connection
between the ECU and the injector if the measured values
are normal.
Specified Value
14 - 17 W
