CAUTION: Carelully remove the ignition wires by pull-
ing on the rubber boots. Do not bend the wires; you might
break them inside.
'1 . Check the condition ot the wire terminals. lJ any ter-
minal is corroded, clean it, and if it is broken or dis-
torted. reolace the wire.
Check for broken,corroded, and bentterminals.

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.

lgnition System
1. Inspect the electrodes and ceramic insulator for:
Spark Plug lnspection
. lmproper gap. Oil-fouling. Carbon deposits. Cracked centerelectrode insulatorDamagedgaskei
Burned or worn electrodes may be caused by:
. Advanced ignition timing. Loose spark plug
. Plug heat range too low. Insufficient cooling
Fouled plugs may be caused bY:. Retarded ignition liming. Oil in combustion chamber. Incorrect spark plug gap
. Plug heat range too high. Excessive rdling'low speed running
. Clogged air cleaner element. Deteriorated ignition coil or ignition wires
81881, 818C5 engine:
. Adjust the gap wjth a suitable gapping tool, and
replace the plug if the center electrode is rounded
as shown below.
Electrode Gap:
Standard 'l .1 ; r mm {0.043 ; ooa in)

3.818C1 engine:
a Do not adjust the gap ol a platinum tip plug;
replace the spark plug it the center electrode is
rounded or if the gap is not within the specifi-
cattons.
Electrode Gap:
Standard I t.s-3., mm (0.051-3.oo4in)

Apply a small quantity ot anti-seize compound to the
plug threads belore installing the plugs.
Screw the plugs into the cylinder head tinger tight,
then torque them to 18 N.m (1 .8 kgf.m, 13lbf.ft).
