-Starter Test
NOTE; The air temoerature must be between 59 and
100'F (15 and 38"C) before testing.
Recommended Procedure:
. Use a staner system tester.
. Connect and operate the equipment in accordance
with the manufacturer's instructions.
. Test and troubleshoot as described,
Alternate Procedurg:
. Use the following equipment:- Ammeter, 0 - 400 A
- Voltmeter, 0 - 20 V (accurate within 0.1 volt)
- Tachometer, 0 - 1,200 rpm
. Hook up a voltmeter and ammeter as shown.
NEGATIVETERMINAL
NOTE: After this test, or any subsequent repair. reset
the ECM/PCM to clear any codes (see section l1)
Check the Start€r Engagemont:
1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box,
2. Turn the ignition switch to START (llll with the shift
lever in E or E position (rVT) or with the clutch pedal
depressed {M/T). The starter should crank the engine.
. lf the starter does not crank the engine, go to
step 3.
. lf itcranksthe engineerraticallyortooslowly, go
to "Check for Wear and Damage" on the next
page.
Check the battery. battery positive cable, ground,
starter cut relay, and the wire connections for loose-
ness and corrosion, Test again.
lf the starter still does not crank the engine, go to
step 4,
Unplug the connector (BLK,/WHT wire and solenoid
terminal) from the starter,
Connect a jumper wire from the battery positive (+)
terminal to the solenoid terminal.
The starter should crank the engine.
. lf the starter still does not crank the engine,
remove it, and diagnose its internal problem
. lf the startercranksthe engine, goto step 6.
Check the ignition switch (see page 23-891.
Check the starter cut relay and clutch interlock switch
(see page 23-86,87).
Check the A/f gear position switch (see page 23-154).
Check for an open in the wire between the ignition
switch and starter.

Starting System
Starter Test lcont'dl
Ch€ck tor Wear and Damage
The starter should crank the engine smoothly and
steadily, lf the starter engages. but cranks the engine
erratically, remove it, and inspect the starter drive gear
and torque converter or flywheel ring gear for damage.
. Check the drive gear overrunning clutch for binding
or slipping when the armature is rotated with the
drive gear held,- lf damaged. replace the gears.
Check Cranking Voltsge and Curr€nt Draw
Cranking voltage should be no less than 8.5 volts.
Current draw should be no more than 350 amperes.
lf cranking voltage is too low, or current draw too high,
check for;
. dead or low batterv.
. open circuit in starter armature commutator seg-
ments,
. starter armature dragging.
. shorted armature winding.
o excessive drag in engine.
Check Cranking rpm
Engine speed during cranking should be above 100 rpm,
lf speed is too low, check for:
. loose battery or stanerterminals.
. excessively worn starter brushes,
. open circuit in commutator segments.
o dirty or damaged helical spline or drive gear.
. defective drive gear overrunning clutch.
Check Siarter Disengag€ment
With the shift lever in El or @ position (A/T) or with the
clutch pedal depressed (M/T), turn the ignition switch to
START (lll), and release to ON (ll).
The starter drive gear should disengage from the torque
converter or flywheel ring gear when you release the
Key.
lf the drive gear hangs up on the torque converter or fly-
wheel ring gear, check for:
. solenoid plunger and switch malfunction,
. dirty drive gear assembly or damaged overrunning
clutch.
Starter Solenoid Test
1. Check the hold-in coil for continuitv between the S
terminal and the armature housing (ground). The
coil is OK if there is continuitv,

STARTERCAELE B TERMINALMOUNTING NUTI N.m {0.9 kgf.m,7 tbf.ft)
Check the pull-in coil for continuity between the S
and M terminals. The coil is OK if there is continuity.

Jlgnition Control Module (lCMl Input Test
NOTE:
. See section 1'l when the malfunction indicator lamp
(MlL) turned 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
1. Remove the distributor ignition (Dl) cap, the distrib-
utor ignition (Dl) rotor and the leak cover (TEC).
2. Disconnect the wires from the lCM.
HITACHI:
BLK/YEL
TEC:
Turn the ignition switch ON (ll). Check for voltage
between the BLK/YEL wire and body ground.
There should be battery voltage.
. lf there is no battery voltage, check the BLK/YEL
wire between the under-dash fuse/relay box and
rhe lcM.
. lf there is battery voltage, go to step 4.
Turn the ignition switch ON (ll). Check for voltage
between the wire*r and body ground
There should be battery voltage.
. lfthere is no battery voltage, check:
- the ignition coil.
- the wire*1 between the ignition coil and the
tcM.
. lf there is battery voltage, go to step 5
*1: BLU'wire (HITACHI)
WHT/BLU wire (TEC)
Disconnect the EcM/PCM connector A (32P). Check
for continuity on the YEUGRN wire between the
ECM/PCM and the lCM.
There should be continuity.
Check for continuity on the YEUGRN wire to body
ground.
There should be no continuity.
Check for continuity on the BLUl wire between the
test tachometer connector and the ICM
There should be continuitY.
Check for continuity on the BLUl wire to body ground.
There should be no continuity.
lf all the tests are normal, replace the ICM
