Ignition Control Module: Testing and Inspection

Component Inspection

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

POWER TRANSISTOR
1. Disconnect camshaft position sensor & power transistor harness connector and ignition coil harness connector.
2. Check power transistor resistance between terminals 2 and 8.
If NG, replace distributor assembly.

RESISTOR
1. Disconnect resistor harness connector.
2. Check resistance between terminals 1 and 2.
Resistance: Approximately 2.2 kohms [at 25° C (77° F)]
If NG, replace resistor.
