Ignition Control Module: Testing and Inspection

Ignition Coil and Ignitor Assembly

Using accurate tester, inspect the following items, and replace if detective.

1. Primary resistance
2. Secondary coil resistance

CAUTION: If the resistance is extremely low, this indicates the presence of a short-circuit.

Specified resistance:




[Primary side]
Between terminal No.1 and No.2
0.73 Ohm ± 10 %
Between terminal No.2 and No.4
0.73 Ohm ± 10 %

[Secondary side]
Between (A) and (B)
12.8 kOhm ± 15 %
Between (C) and (D)
12.8 kOhm ± 15 %




3. Insulation between primary terminal and case: 10 MOhm or more.
