Ignition Control Module: Testing and Inspection

CAUTION: An analog-type ammeter should be used.

Power Transistor For Coil No.1 And No.4 Cylinders





1. Connect the negative (-) terminal of the 1 .5 Volt power supply to terminal No.3 of the power transistor; then check whether there is continuity between terminal No.5 and terminal No.3 when terminal No.4 and the positive (+) terminal are connected and disconnected.





NOTE:
Connect the negative (-) probe of the ammeter to terminal No.5.

Power Transistor For Coil No.2 And No.3 Cylinders





2. Connect the negative (-) terminal of the 1 .5 Volt power supply to terminal No.3 of the power transistor; then check whether there is continuity between terminal No.1 and terminal No.3 when terminal No.2 and the positive (+) terminal are connected and disconnected.





NOTE:
Connect the negative (-) probe of the ammeter to terminal No.1.

If the problem is still evident after checking as described above, replace the power transistor.
