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.

5. Check lor 8n op€n in the BLKMHT wire circuit be-
tween the staner and ignition switch, and con-
nectors.
6. Check the ignition switch (see page 23-70).
7, On cars with automatic transmission, check the A/Tgear position switch (neutral position switchl and
connector. On cars with manualtransmission, check
the staner cut relay, clutch interlock switch, and
connectors.
NOTE: Check the No. 39 (5O A) fuse in the under-hood
fuse/relay box for the starter cut relay.
Check tor Woar and Damago:
The starter should crank the engine smoothly and stead-
ily. lf th€ startsr engages, but cranks the engine errati-
cally, remove it. Inspect the starter, drive gear, and
flywheel ring gesr for damage.
a Check the drive gear overunning clutch for binding
or slipping when the armature is rotated with the drivegear held. Replace the gesrs if damaged.
Check Cranking Voltago 8nd Current Draw:
Cranking voltage should be no less than 8.O volts.
Current draw should be no more than 360 amperes.
lf cranking voltag€ is too low, or current draw too high,
check for:
a Fully charged battery
a Open circuit in starter armature commutatot segments
a Starter armature dragging
a Shoned armature winding
a Excessive drag in engine
Chack Cranking rpm:
Engine spsod during cranking should be above 1O0 rpm.
lf spe6d is too low, ch€ck for:
a Loose battsry or starter teminals
a Excessively worn starter brushes
a Open circuit in commutator segments
a Dirty or damaged helical spline or drive gear
a Defective drive gear overrunning clutch
Chock StErtor Disongagomoni:
Press the clutch pedal allth€ way in (M/T), turn the ioni-
tion switch to "lll" and rolease to "11".
The starter drive gear should disengage from the tlywheel
ring gear. When you rolease the key.
lf the drive gear hangs up on th€ flywheel ring gear, check
for:
a Solenoid plunger and switch malfunction
a Dirty drive gear assembly or damaged overrunning

NOTE: Refer to page 23-145fot a diagram of the key-
in leminder circuit, and to page 23-148 Jor the input test
ol the beeper circuit.
When the ignition key is not removed, the key-in reminder
in the integrated control unit senses ground through the
closed ignition key switch. When you open the driver's
door, the beeper circuit senses ground through the closed
door switch, With ground at the "LT BLU" and "GRN/
BLU" terminals, the beeper sounds.
1 . Remove the dashboard lower cover and knee bolster
(see page 23-70).
2. Disconnect the 7-P connector from the main wire
harness.
Check for continuity between the No. 2 and No. 4
terminals in each condition acco.ding to the table.

Engine Oil Pressure
Indicator System
Description
NOTE: Reter to page 23-144 tor the circuit diagram otthe engine oil pressure indicator flasher, snd to page
23-148 lor the input test of the flasher circuit.
The low engine oil pressure indicator tight works in twoways. lt will flash continuously following a momentaryloss of oil pressure, or it will go on and stay on with acomplete loss of oil pressure.
When the engine first starts, before oil Dressure risesabove 29.4 kP8 10.3 kgf/cmr, 4.3 psi), current flowsthrough the low engine oil pressure indicator light andthe oil pressure switch to ground. This tests the circuit.
Wilh the engine running, voltage is applied ro the ftash-er circuit of the integrated control unit. With normal oilpressure, the oil pressure switch is open and the low en-gine oil pressure indicator light does not operate. lf theoil pressure switch closes momentarily (more than O.5secondsl, but then opens again, terminal "yEL/RED,'will
sense ground through the switch. The integrated con-trol unit willthen provide and remove ground for th€ lowengine oil pressure indicator light through terminal"YEL/RED". The light will flash on and olf until the igni-tion switch is turned to "OFF".
lf engine oil pressure falls below 29.4 kPa (O.3 kgJ/cmr,4.3 psi) and does not increase, the oil pressure switchwillstsy closed. The low engine oilpressure indicator lightwill go on and stav on.
NOTE; Refer to page 23-122lot the engine oil pressure
switch test.
Lights-on Reminder

Description
Chime Test
Remove the dashboard lower cover and knee bolster
{see page 23-70).
Disconnect the 2-P connector t.om the dashboardwire hamess.
Test the chime by connecting battery power to the"A" te.minal and ground to the "B" terminal, andcycling the power on-off repestedly.
lf the chime fails to sound every time power is cy-cled, reDlace it.
NOTE: Refer to page 23-145 tor a diagram of the lights-
on reminder circuit, and to page 23-149 for the input
tests of the circuit.
When the ignition key is turned to OFF 8nd removed. withthe lights on, voltage is apptied to the reminder circuitin the integrat€d control unit. When you open the driver,sdoor, the circuit senses ground through the closed doorswitch.
With voltage at the "H" terminal, ground at the"GRN/BLU2" terminal and no voltage at the ,,F,' termi-nal, the chime sounds to remind the driver to turn oJf thelights.
