lgnition Control Module (lCMl Input Test
NOTE:
. See section 11 when the malfunction indicator lamp(MlL) comes on.
. Perform an input test for the ignition control module(lCM) after finishing the fundamental tests for the
ignition system and the fuel and emissions systems.
. '97 -'98 models: The tachometer should operate nor-
mally if the ICM is OK.
L Remove the distributor ignition (Dl) cap, the distrib-
utor ignition (Dl) rotor, and the leak cover.
2. Disconnect the wires from the lCM.

Turn the ignition switch ON {ll). Check for voltage
between the BLK,^/EL wire and body ground. There
should be battery voltage.
. lf there is no battery voltage, check the BLK/rEL
wire betlveen the ignition switch and the lclvl.
. lf there is baftery voltage, go to step 4.
Turn the ignition switch ON (ll). Check for voltage
between the WHT/BLU wire and body ground. There
should be battery voltage.

B (25P). Check for continuity on the YEUGRN wire
between the ICM and ECM/PCM. There should be

Check for continuity on the YEUGRN wire to body
ground. There should be no continuity.
Reconnect the ECM/PClvl connector.
'97 -'98 models: Check for continuity on the BLU
wire between the test tachometer connector and the
lCM. There should be continuity.
'97 -'98 models: Check for continuity on the BLU

lgnition Coil Test
Using an ohmmeter, measure resistance between the
terminals. lf the resistance is not within sDecifications,
replace the ignition coil.
NOTE: Resistance will vary with the coil temperature;
specifications are at 68"F (20'C).
Plimary Winding Resistance
{Between the A and B terminals):
0.6it - 0.77 0
Secondary Winding Resistance

lgnition Wire Inspection and Test
1.Carefully remove the ignition wires by pulling on
the rubber boots. Do not bend the wires; you might
break them inside.
Check the condition of the ignition wire terminals. lf
any terminal is corroded, clean it, and if it is broken
or distorted, replace the ignition wire.
IGNITION WIRE
Connect the ohmmeter probes and measure resis-
tance.
lgnition Wire Resistance:
25 kO max. at 68'F 120'Cl

Spark Plug Inspection
Inspect the electrodes and ceramic insulator for:
. lmproper gap. Oil-fouling. Carbon deposits. Cracked centerelectrode insulator
Burned or worn electrodes may be caused by:
. Advanced ignition timing
. Loose spark plug
. Plug heat range too hot
. Insufficient cooling
Fouled plug may be caused by:
. Retarded ignition timing
. Oil in combustion chamber
. Incorrect spark plug gap
. Plug heat range too cold
. Excessive idling/low speed runnang
. Clogged air cleaner element
. Deteriorated ignition wires

2. Check the electrode gaP.
. Adjust the gap with a suitable gapping tool.

Rotor Slip Ring Test
1. Check the resistance between the slip rings.
There should be 1.8 - 3.0 ohms.
. lf resistance meets the specification, go to step 2
. lf resistance does not meet the specification,
replace the alternator.
SLIP RINGS
Check that there is no continuity between the slip
rings and the rotor or rotor shaft.
lf the rotor fails either continuity check, replace the
alternator.
