Control Module (lCMl Input Test
NOTE:
a See section I 1 if the malfunction indicator lamD (MlL)
blinks.
a Pertorm an input test for the ignition control module
(lCM) after finishing the fundamental tests for the ig-
nition system and the fuel and emissions systems.
a The tachometer should operate normally.
1. Remove the distributor cap, the distributor rotor, and
the leak cover.
2. Disconnect the BLK/YEL, WHT/BLU, YEL/GRN, and
BLU wires from the lCM.
3. Turn the ignition switch ON. Check for voltage be-
tween the BLK/YEL wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check the BLK^/EL
wire between the ignition switch and the lCM.
a lf there is battery voltage, go to step 4.
YEL/GRN wlRE
4.Turn the ignition switch ON. Check for voltage be-
tween the WHT/BLU wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check:- lgnition coil- WHT/BLU wire between the ignition coil and
the ICM
a lf there is battery voltage. go to step 5.
Check the YEL/GRN wire between the ECM and the
tcM.
Check the BLU wi.e between the tachometer and the
rcM.
It all tests are normal, replace the lCM.
