lgnition Timing Inspection and Setting
2.
1.Check the idle speed, and adjust it if necessary (see
section 1 1).
Pull out the service check connector 2P (BRN and
BLK wires) from the connector holder located under
the dash on the front passenger side, then connect
the scs service connector (P/N 07PAz - 0010100) to
it.
Start the engine. Hold the engine at 3,000 rpm with
no load (A/T in N or E, Mff in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. I ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights, blower fan, rear window defogger, and
air conditioner are not operating.
lgnition Timing:

6. lf necessary, adjust the ignition timing as follows.
Loosen the distributor mounting bolts, and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing or clockwise to retard the tim-
t no,

Distributor Replacement
Removal:
1. Disconnect the connector from the distributor.
2. Disconnect the ignition wires from the distributor
ignition (Dl) cap.
3. Remove the mounting bolts from the distributor,
then remove the distributor from the cylinder head.

MOUNTING BOLTS8 x 1.25 mm2,1N.m {2.,1kgrf.m, 17 lbf ftl
lnstallation:
1. Bring the No. 1 piston to compression stroke TDC.
2. Coata new O-ring with engine oil, then install it.
3. Align the lug on the end of the distributor and its
mating grooves in the camshaft end, then slip the
distributor into position.
NOTE: The lug on the end of the distributor and its
mating grooves in the camshaft end are both offset
to eliminate the possibility of installing the distribu-
tor 180o out of time.
4. Installthe mounting bolts, and tighten them lightly.
5. Connect the ignition wires to the distributor ignition(Dl) cap as shown,
No. 1CYLINDERMARK
6. Connect the connector to the distributor.
7. Set the ignition timing (see previous page).
8. After setting the ignition timing, tighten the mount-
ing bolts.

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.
. lf there is no batteryvoltage, check:- ignition coil.- WHT/BLU wire between the ICM and ignition
corl.
. lf there is battery voltage, go to step 5,
'97 model: Disconnect the ECM/PCM connector A(32P). Check for continuity on the YEL/GRN wire
between the ICM and ECM/PCM. There should be
continuity.'98 - 00 models: Disconnect the ECM,PCM connector
B (25P). Check for continuity on the YEUGRN wire
between the ICM and ECM/PCM. There should be
continuity.
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
wire to body ground. There should be no continuity.
lf all the tests are normal, replace the lCM.

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.

Connect the ohmmeter probes and measure resis-
tance.

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.

Goolant Temperature Gauge
Gauge Testing
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testin9.
2. Make sure the ignition switch is OFF, then discon-
nect the YEL/GRN wire from the coolant tempera-
ture sending unit. and ground it with a jumper wire.
YEL/GRNWIRE
Turn the ignition switch ON {ll). Check that the
pointer of the coolant temperature gauge starts
moving toward the "H" mark. Turn the ignition
switch OFF before the pointer reaches "H" on the
gauge dial. Failure to do so may damage the gauge.
lf the pointer of the gauge does not move at all,
check for an open in the YEL/GRN wire.
lf the wires are OK, replace the coolant temperature
gauge.
lf the coolant temperature gauge works, test the
coolant temperature sending unit.
