lgnition Control Module (lCM) Input Test
NOTE:
a See section 1 1 if the malfunction indicator lamp (MlLl
has been reported on.a Perform 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 distributo. ignition (Dl) cap, the rotor,and the leak cover.
2. Disconnect the BLK/YEL, WHT/BLU, YEL/GRN, andBLU wires from the lCM.
3. Turn the ignition switch ON {ll}. Check for voltage
between the BLK/YEL wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check the BLKiYEL
wire between the ignition switch and the lCM.a It there is battery voltage, go to step 4,

4. Turn the ignition switch ON (ll). Check for voltage
between the WHT/BLU wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check:- ignition coil.- WHT/BLU wire between the ignition coil and
tcM.
a lf there is battery voltage, go to step 5.
5. Disconnect the 32P connector from the ECM, and
check for continuity on the YEUGRN wire between
the ICM and ECM.
There should be continuity.
6. Check for continuity on the YEL/GRN wire to bodygrouno.
There should be no continuity.
7.Reconnect the ECM 32P connector.
Disconnect the gauge assembly 13P connector,
TCM 26P connector, and cruise control l4P connector.
9. Check for continuity on the BLU wire between the
ICM and tachometer.
There should be continuity.
'10. Check for continuity on the BLU wire to body ground.
There should be no continuity.
1 1 . lf all the tests are normal, reconnect the connectors,
and replace the lCM.

Troubleshooting
NOTE:
a The numbers in the table show the troubleshooting sequence.
a Belore troubleshooting,- check the No. 25 (7.5 A) and No. 14 (7.5 A) fusds in the under-dash fuse/relay box. and the No. 4l (100 A), No. 42(40 A), and No. 52 (20 A) fuses in the under-hood fuse/relay box.- check that the horn sounds.- check the tachometer to see if it works properly.
