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

M161 ENGINE ELECTRICAL 1E2-11
Inspection & Maintenance (for E2.3 MSE)
1. Measure the primary resistance between the cable terminals1 and 15 after removing the ignition cable wiring connector
(1 and 15) with ignition switch OFF. Notice Replace the ignition coil if out of the specified resistance.
T1/2 : between No.71 and No.69
Notice Check the ignition cable and the ECU if out of the
specified value.
3. Measure the secondary cable resistance between the ignition coil 5a and 5b using a multimeter.
2. Measure the primary voltage(T1/1) between the ECU
terminals No.72 and No.69 during the engine cranking (starter motor activated).
Specified Value 6 - 8.5 K
Specified Value0.9 - 1.6
Specified Value 200 - 350 V
