Starter Test
NOTE: The air temperature must be between 59 and100F (15 and 38C) before testing.
Recommended Procedure:
. Use a staner system tester.
. Connect and operate the equipment in accordance
with the manufacturers instructions.
. Test and troubleshoot as described.
Alte.nate Procedure:
. 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.
NOTE: After this test, or any subsequent repair. reset
the ECM/PCM to clear any codes (see section 1 1).
Check the Starter Engagement:
1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box.
2. Turn the ignition switch to START (lll) with the shift
lever in E or E position (A/T) or with the clutch
pedal depressed {M/T). The starter should crank the
eng ine.
. lf the starter does not crank the engine, go to
step 3.
. lf it cranks the engine erratically or too slowly, go
to Check for Wear and Damage on the next
page.

Check the battery, battery positive cable, ground.
staner cut relay, and the wire connections for loose-
ness and corrosion. Test again.
lf the staner still does not crank the engine, go to
step 4.
Unplug the connector (BLK /VHT wire and solenoid
terminal) from the starter.
Connect a jumper wire from the baftery 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 starter cranks the engine, go to step 6.
Check the ignition switch (see section 23).
Check the starter cut relay {see section 23}.
Check the IVT gear position switch (A/T) or the clutch
interlock switch (M[).
Check for an open in the wire between the ignition
switch and starter.

Starting System
Starter Test (contdl
Check lor Wear and D8mage
The starter should crank the engine smoothly and
steadily. lf the staner engages, but cranks the engine
erratically, remove it, and inspect the starter drive gear
and torque converter ring gear or flywheel ring gear for
oamage.
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 Voltage and Current Draw
Cranking voltage should be no less than 8.7 volts on AyT
models, and 8.0 volts on M/T moders.
Current draw should be no more than 230 amperes on
A,/T models, and 200 amperes on M/T models.
lf cranking voltage is too low, or current draw too high,
check for:
. dead or low battery.
a open circuit in starter armature commutator seg,
ments.
. starter armature dragging.
. shorted armature winding.
. excessive drag in engine.
Check Cranking rpm
Engine speed during cranking should be above 100 rpm.
lf speed is too low, check for:
a loose baftery or starter terminals.
. excesslvely worn staner brushes
. open circuit in commutator segments.
. dirty or damaged helical splines or drive gear.
a defective drive gear overrunning clutch.
Check Starter Disengagement
With the shift lever in @ or @ position (A,iT) 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 ring gear or flywheel ring gear when you
release the key.
lf the drive gear hangs up on the torque converter ring
gear or flywheel 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 continuity between the S
terminal and lhe armature housing (ground). The
coil is OK if there is continuity.

Brush Inspection
Measure the brush length. lf it is not within the service
limit, replace the brush (or brush holder assembly).
Brush Lsngth
Standard {Newl: 14.0 - I1.5 mm (0.55 - 0.57 inl
Servico Limit: 9.0 mm (0.35 in)
NOTE: To seat new brushes after installing them in their
holders. slip a strip of #500 or #600 sandpaper, with the
grit side up, over the commutator and smoothly rotate
the armature. The contact surface of the brushes will be
sanded to the same contour as the commutator.

Overrunning Clutch Inspection
Slide the overrunning clutch along the shaft. Does it
move freely? lf not, replace it.
Rotate the overrunning clutch both ways. Does it
lock in one direction and rotate smoothly in
reverse? lf it does not lock in either direction or it
locks in both directions, reDlace it.
3.lf the starter drive gear is worn or damaged, replace
the overrunning clutch assembly; the gear is not
available separately.
Check the condition of the torque converter ring gear
or the flywheel ring gear if the starter drive gear
teeth are damaged.

Armature Inspection and Test
1. Inspect the armature for wear or damage due to
contact with the field winding. lf there is wear or
damage. replace the armature.
Check the commutator surface. lf the surface is dirty
or burnt, resurface with emery cloth or a lathe with-
in the tollowing specifications, or recondition with
#500 or #600 sandDaoer.
lnspect for damage.

3. Check the commutator diameter. lf commutator
diameter is below the service limit, reolace the
armalure.
Commutator Diameter
Standard (Newl: 27.9 - 28.0 mm (1.09 - 1.10 in)
Service Limilr 27.0 mm (1.06 inl
lf the commutator runout is within the service
limit, check the commutator for carbon dust or
brass chips between the segments.
lf the commutator runout is not within the ser-
vice limit, replace the armature.
Commutator Runout
Standard (Newl: 0 - 0.02 mm (0 - 0.0008 in)
