M162 ENGINE ELECTRICAL 1E1-11
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
