Always use Honda Manual Transmission Fluid (MTF). Using motor oii can cause stiffer shifting because it does
not contain the Drooer additives.
Always use Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and decrease the life of
the system.

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.

Starting System
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.

lf the eiectric cu rrent and motor speed meet the
specifications when the battery voltage is at 1 1.5 V,
the staner is working properly,

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:

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.
