Starter Circuit Troubleshooting
NOTE:. Airtemperature must be between 59'and 100'F (15'
and 38'C) during this procedure.
. After this test, or any subsequent repair, reset the
engine controle module (ECM) to clear any diagnostlc
trouble codes (DTCS) {see page 11-4).. The battery must be in good condition and fully
charged.. lf you disconnect the baftery, do the ECM idle learn
procedure (see page 11-139).
Recommended Procedure:. Use a starter system tester.. Connect and operate the equipment in accordance
with the manuf acturer's instructions.
Alternate Procedure
1. Hook up the following equipment:. Ammeter, 0 400 A. Voltmeter, 0 20 V (accurate within 0.1 volt). Tachometer,0 1200 rpm
2.Remove the No. 17 (15A) fuse from the under-dash
fuse/relay box.
With the clutch pedal pressed, turn the ignition
switch to start (lll).
Did the starter crank the engine normally?
YES-The starting system is OK.I
NO-Go to step 4.
3.
L
4-5
4. Check the battery condition. Check electrical
connections at the battery, the negative baftery
cable to body, the engine ground cables and the
starter for looseness and corrosion. Then try
starting the engine again.
Did the statter crank the engine?
YES Repairing the loose connection fixed the
problem. The starting system is now OK.!
NO lf starterwill notcranktheengine atall, goto
step 5. lf it cranks the engine erratically or too
slowly, go to step 7. lf it won't disengage from the
flywheel ring gear when you release the key, check
for the following until you find the cause.
. Solenoid plunger and switch malfunction. Dirty drive gear or damaged overrunning clutch
5. Make sure the transmission is in neutral, then
disconnect the starter subharness 1P connector (A)
from the engine wire harness 'lP connector (B).
Connect a jumper wire from the battery positive
terminal to the starter subharness 'l P connector.
Did the starter crank the engine?
YES-Go to step 6.
NO Check the BLK,ANHT wire between the starter
subharness 1P connector and the starter. lf wire is
OK, remove the starter, and repair or replace as
necessary.

6. Check the following items in the order listed untilyou find the open circuit.
. Check the BLIVWHT wire and connectors
between the under-dash fuse/relay box and theignition switch, and between the under-dash
fuse/relay box and the starter.. Check the ignition switch {see page 22-53).. Check the clutch interlock switch and connector.. Check the starter cut relay (see page 22-51).. Check LT GRN wire between the starter cut relayl
under-dash fuse/relay box and the clutch
interlock switch.. Check the BLK wire between the clutch interlock
switch and G501.
7, Check the cranking voltage and current draw.
ls ctanking voltage greatet than or equal to 8.7 V
and current draw less than or equal to 230 A?
YES-Go to step 8.
NO Replace the starter. or remove and
disassemble it, and check these items until you find
the cause.
. Starter armature dragging. Shorted armatu re winding. Excessive drag in engine
8. Check the engine speed while cranking the engine.
ls the engine speed above 100 tpm?
YES Go to step 9.
NO-Replace the starter, or remove and
disassemble it, and check for the following untilyou find the cause.
. Excessively worn starter brushes. Open circuit in commutator brushes. Open circuit in starter armature commutator
segments. Dirty or damaged helical splines or drive gear. Faulty drive gear clutch
9. Remove the starter, and inspect its drive gear andthe flywheel ring gear for damage. Replace anydamaged pans.I

Clutch Interlock Switch Test
1. Disconnect the clutch interlock switch 2P connector.
2. Remove the clutch interlock switch (A).
Check for continuity between the terminals
according to the table.
. lf the continuity is not as specified, replace the
clutch interlock switch.. lf OK, install clutch interlock switch and adjust
the pedal height (see page 12-4l..

Starter Solenoid Test
1. Disconnect the S and lvl connectors from the starter
solenoid.
2. Check the hold-in coil for continuity between the S
terminal and the armature housing (ground). There
should be continuity.
. lf there is continuity, goto step 3.. lf there is no continuity, replace the solenoid,
3. Check the pull-in coil for continuity betwee n the S
terminal and M terminal. There should be
continuity,
. lf there is continuity, the solenoid is OK.
. lf there is no continuity, replace the solenoid,

Starter Performance Test
1,Disconnect the wires from the S terminal and the M
termrnal.
Make a connection as described below using as
heavy a wire as possible (preterably equivalent to
the wire used for the vehicle). To avoid damaging
the starter, never leave the battery connected for
more than 10 seconds,
Connect the battery as shown. Be sure to
disconnect the starter motor wire from the solenoid.
lf the starter pinion moves out, it is workingpropefly.
Disconnect the battery from the M terminal. lf thepinion does not retract, the hold-in coil of the
solenoid is working properly.

5. Disconnect the battery from the starter body. lfthepinion retracts immediately, it is working properly.
Clamp the starter firmly in a vise.
Connect the starter to the battery as described in
the diagram below, and confirm that the motor
sta rts and keeps rotating.
