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.

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.

Starter Replacement
1. Make sure you have the anti-theft code for the radio.
then write down the frequencies for the radio's
preset buttons.
2. Disconnect the negative cable from the battery first,
then disconnect the positive cable.
3. Disconnect the knock sensor connector.
4. Remove the bolt (A) securing the harness bracket,
then remove the intake manifold bracket (B).

Charging Circuit Troubleshooting
lf the charging system indicator does not come on or
does not go off, or the battery is dead or low, test these
items in the order listed below:
Battery (see page 22-50)
Charging system indicator
Alternator and regulator circuit
Alternator control system
Charging System Indicator Test
1. Turn the ignition switch ON {ll).
Does the chatging system indicator come on?
YES Go to step 2.
NO Go to step 3.
2. Start the engine.
Does the charging system indicator go off?
YES-Charging system indicator circuit is OK. Go
to the Alternator and Regulator circuit Test. t
NO-Go to step 3.
3. Turn the ignition switch OFF.
4. Troubleshoot the multiplex control system (see
page 22 172).
ls the multiplex control system OK?
YES Go to step 5.
NO Check the multiplex control system as
indicated by the diagnostic trouble code (DTC) (see
step 8 on page 22-172).1
5. Disconnect the engine wire harness 6P connector
from the starter sub harness 6P connector.

Installthe battery. Clean the battery posts and
cable terminals with sandpaper, then assemble
them and apply grease to prevent corrosion.
Check that the transmission shifts into gear
smoothly.
Inspect for fuel leaks. Turn the ignition switch ON(ll) {do not operate the starter) so that the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation two or three times, then
check for fuel leakage at any point in the fuel line.
Refillthe engine with engine oil (see page 8-5).
Refill the transmission with fluid (see page 13-3).
Refill the radiator with engine coolant, and bleed
air from the cooling system with the heater valve
open (see page 10-6).
Perform the engine control module (ECM) idle learnprocedure (see page 11-139).
Inspect the idle speed (see page 1 1-138).
Inspect the ignition timing (see page 4-17).
Check the wheel alignment {see page 18-4).
