Functions
1. Firing order : 1-5-3-6-2-4
2. The ignition cables are located on the cylinder head cover.
Each ignition coil provides the high voltage to two spark
plugs simultaneously.
- T1/1 : cylinder 2 and 5
- T1/2 : cylinder 3 and 4
- T1/3 : cylinder 1 and 6
Removal & Installation Procedure
1. Disconnect the negative battery cable (1).
2. Remove the ignition cable connector from the ignition cable.
3. Disconnect the secondary spark plug connectors from the
each spark plugs and remove the ignition cable.
Installation Notice 3. The secondary output voltage (5a) is supplied to the No.2
cylinder spark plug through the spark plug connector. The
secondary output voltage (5b) is supplied to the No.5 cylinder
spark plug through the ignition cable. The guide pin (W)
acts as a ground while the ignition cable is operated.
lMake sure that the ignition cables are correctly routed.
lExactly install the ignition cable guide pin into the vehicle
to be grounded.
4. Installation should follow the removal procedure in the
reverse order.
Tightening Torque 9 - 11 Nm

Circuit Diagram
Inspection & Maintenance Procedure (for MSE)
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
