Startel Test
NOTE: The air temDerature must be between 59 8nd
10OoF (15 and 38oC) before testing.
Recommendsd Procodure:
a Use a staner svstem tester.
a Connect and operate the equipment in accordance
with the manutacturer's instructions.
a Test and troubleshoot as described.
Altohato Procedure:
a Use the following equipment:- Ammeter. 0-4OO A- Voltmeter, O- 20 V {accurate within 0.1 volt)
- Tachometer, O- 120O rpm
a Hook up voltmeter and ammeter as shown'
NEGATIVE TERMINAL
NOTE: After this test, or any subsequent repair,
reset the ECM to clear any codes (see section 1 1)

Chock Stan€r Engag6ment:
1. Disconnect the 2-P connector (ignition coil primary
lead) from the distributor.
Press the clutch pedal allthe way in (M/T), and turn
the ignition switch to "Start". The starter should
crank the engine.
NOTE: On cars equipped with manual transmission,
the engine will not crank unless the clutch pedal is
fully depressed.
lf the staner does not crank the engine go to step 3.
Check the baftery, battery positive cable, ground,
and the wire connections for looseness and cor-
rosion,
Test again. lf the starter still does not crank the en-
gine, go to step 4.
Bvpass the ignition switch citcuit as follows {make
sure the transmission is in neutral):
Unplug the connector (BLK/WHT wire and solenoid
terminsl) trom the starter. Then connect a jumper
wire from the battery positive ( + ) terminal to the
solenoid terminal. The starter should crank the
engrne.
a lf the starter still does not crank the engine,
replace it and diagnose its internal problems.
a lf the starter cranks the engine, go to step 5.

1 . Remove the dashboard lower cover and knee bolster
(see page 23-70), then disconnect the 2-P connec-
tor from the switch.
2. Check tor continuity between the terminals accord-
ing to the table.
lf necessary. replace the switch or adjust the switch
oosition (see section 12).

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.

a lf there is battery voltage. go to step 5.
Check the YEL/GRN wire between the ECM and the

Alternator Belt Inspection and Adjustment
Deflection Method:
Apply a force of 100 N (1o kgt, 22 lbJ) and measure the
deflection between the alternator and the crankshatt
pulley.
Detlsction:9-11 mm (0.35-O.43 inl
NOTE; On a brand-new belt {one that has be€n run
for less than five minutes), the deJlection should be
6-8 mm 1O.23-O.32 in) wh€n first measured. lf
the belt is worn or damaged, replace it.

2. Move the alternator to obtain the proper belt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the deflection ot the belt.
NOTE: lt necessary, adiust the P/S pump belt (see
section 17) and A/C compressor belt lsee section
22t.

Boh Tsnsion Gaug6 Mothod:
Foltowing the gauge manuJacturer's instructions, attach
the belt tension gauge to the belt and measure the
tension.
Tension: 340-49O N (35-50 kgl, 77-110 lbfl
NOTE: On a brand-new belt (one that has been run
for less than tive minutes), tension should be
690-880 N (70-90 kgt, 154- 198 lbJ) when tirst
measured. lf the belt is worn or damaged, replace it.
lf adi$tmsnt is nscaasary:
1. Loosen the alternator adiusting nut and mounting
nut.
2. Move ths ahernator to obtain the proper bslt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the tension of the belt,
NOTE: lf necessary, adjust the P/S pump belt (see
