1E1-10 M162 ENGINE ELECTRICAL 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 cylinderspark plug through the ignition cable. The guide pin (W)acts as a ground while the ignition cable is operated.
Make sure that the ignition cables are correctly routed.
Exactly 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 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
