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

BATTERY
Inspection Notice
When charging the battery, do not leave the inflammable
objects around it.
When checking the electrolyte of battery, put on
an eye protector and gloves.
1. Inspect the surface of the battery and replace if any defects were found on it.
2. Check if the specific gravity of the electrolyte is within the specified value. Notice
Replace the battery if the maximum tolerance of the
electrolyte between cells is out of the specified value.
Measure the specific gravity in the approx. 20 °C
of ambient temperature.
3. Replenish the electrolyte if necessary. Battery capacity(Ah)Battery specific gravity Max. tolerance between cells
