Ignition Control Module: Testing and Inspection

COMPONENT INSPECTION

Ignition coil






1. Disconnect ignition coil harness connector.
2. Check resistance as shown in the figure.

Terminal / Resistance at 25°C (77°F)
(1) - (2) (Primary coil): Approximately 1.0 Ohms
(1) - (3) (Secondary coil): Approximately 10k Ohm

If NG, replace ignition coil.

Power transistor

1. Disconnect power transistor harness connector.









2. Check power transistor resistance between terminals (2) and (3).
If NG, replace power transistor.

Resistor






1. Disconnect resistor harness connector.
2. Check resistance between terminals.

Resistance: Approx. 2.2K Ohms [at 25°C (77°F)]

If NG, replace resistor.
