Ignition Control Module: Testing and Inspection

INSPECTION OF IGNITER





1. CHECK POWER SOURCE LINE VOLTAGE

(a) Disconnect the connector 6-P.

(b) Turn the ignition switch ON.

(c) Using a voltmeter, connect the positive (+) probe to the terminal 3 of harness side and negative (-) probe to body ground.

Voltage: Approx. 12 V

(d) Connect the connector 6-P.



2. CHECK POWER TRANSISTOR IN IGNITER

(a) Disconnect the connector 4-P.

(b) Disconnect each ignition coil from its connector.

(c) Turn the ignition switch ON.





(d) Using an ohmmeter, connect terminal 2 of ignition coil C and body ground.

(e) Using a 3V dry cell battery, apply voltage to terminal 2 of connector 4-P.

As voltage is applied, check that there is momentary continuity.





(f) Using an ohmmeter, connect terminal 2 of ignition coil A and body ground.

(g) Using a 3V dry cell battery, apply voltage to terminal 4 of the 4-P connector.

(h) With terminal 4 connected apply voltage to terminal 2 of connector 4-P. As you apply voltage, check that there is momentary continuity.





(i) Using an ohmmeter, connect terminal 2 of ignition coil B and body ground.

(j) Using a 3V dry cell battery, apply voltage to terminal 3 of the 4-P connector.

(k) With terminal 3 connected apply voltage to terminal 2 of connector 4-P. As you apply voltage, check that there is momentary continuity.
