Ignition Control Module (ICM) Input Test
Disconnect the 8-P connector from the ignition control
module (ICM).
Inspect the connector and socket terminals to be sure
they are all making good contact.
• If the terminals are bent, loose, or corroded, repair
them as necessary, and recheck the system.
• If the terminals look OK, make the following input
tests at the connector.
— If any test indicates a problem, find and correct the
cause, then recheck the system.
— If all the input tests prove OK, the ICM must be faul-
ty; replace it.

NOTE:
• The tachometer should operate normally.
• See section 11 when the malfunction indicator
lamp (MIL) blinks.
• If necessary, perform an input test on the ICM
after finishing the fundamental tests for the igni-
tion system and fuel and emission systems.
