Ignition Control Module: Testing and Inspection

Using accurate tester, inspect the following items, and replace if defective.
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 ohms ± 10%
Between terminal No.2 and No.4 0.73 ohms ± 10%




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

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