-lgnition Timing Inspection and Setting
1.Check the idle speed, and adjust it it necessary (see
section 'l '1 ).
Pull out the service check connector 2P (BRN and BLK
wires) from the connector holder located under the
dash on the front passenger side, then connect the
SCS service connector (T/N 07PAZ - 0010'100) to it.
Start the engine. Hold the engine at 3.000 rpm with
no load {A,/T in E or E. M/T in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. 1 ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights. blower fan, rear window defogger, and
air conditioner are not operating.

lnstallation:
NOTE: Before you install the distributor. bring the No. 1
piston to compression stroke TDC.
1. Coat a new O-ring with engine oil, then install it.
2. Slip the distributor into position
NOTE: The lug on the end of the distributor and its
mating grooves in the camshaft end are both offset
to eliminate the possibility of installing the distribu-
tor 180" out of time.
3. Installthe mounting bolts, and tighten them lightly.

)Erasing the DTC Memory
To erase the DTC(s) from the SRS unit, use a Honda
PGM Tester (see the Honda PGM Tester SRS vehicle
System Supplement) or the following procedure
1. Make sure the ignition switch is OFF
2. Connect the SCS service connector to the MES con-
nector (2P). Do not use a jumper wlre.

after the SRS indicator light went off.
The SRS indicator light comes on again. Reconnect

Troubleshooting Intermittent
Failures
lf there was a malfunction, but it doesn't recur, it will be
stored in the memory as an intermittent failure, and the
SRS indicator light comes on.
Afte. checking the DTC, troubleshoot as lollows:
1. Read rhe DTC {see "Reading the DTC"}.
Erase the DTC memory (see "Erasing the DTC
Memory").
With the shifi lever in neutral, turn the ignition switch
ON (ll), and lei the engine idle.
The SRS indicator light comes on for about six sec-
onds and goes off.

Shake the wire harness and the connector, take a test
drive (quick acceleration, quick braking, cornering),
and turn the steering wheel fully left and right, and
hold it there for five lo ten seconds to find the cause
of the intermittent failure.
lf the problem recurs, the SRS indicator light will
stay on.

Connector Views
To see the configuration of a connector's cavities, look up its view number in the Connector
View section in the back of the book. Each view includes the color of the connector, where it
is located, and what it connects to.
Use the Connector Views to help locate the proper cavity when you need to probe a
connector. lt can be especially helpful if the connector has more than one wire of the same
cotor.
Connector views can also be used to help diagnose multiple symptoms in separate circuits
which could be caused by a single problem in a connector shared by those circuits. Here's
how:
1. Pick one of the multiple symptoms and look up the schematic for that circuit.
2. Make a list of all the in-line and fuse box connectors in that schematic (include page
numbers).
3. Then, in the Connector View section, look up each connector on your list to see il circuits
related to the other symptoms run through one of them. lf they do, inspect that connector
for the oroblem.
Example: The blower, rear window defogger, and the windshield wiper don't work. List all
in-line and fuse box connectors in the blower controls circuit and then check the Connector
View section (sample below). You find that C324 is common to the rear window defogger
circuit and wiper/washer circuit, so you inspect C324 and find the problem, bent terminals.

In the "OHMS" range, the DVOM will measure
resistance between two points along a circuit.
Low resistance means good continuity.
Diodes and solid-state devices in a circuit can
make a DVOM give a false reading. To check
a reading, reverse the leads, and take a
second reading. lf the readings differ, the
component is affecting lhe measurement.
Jumper Wire
Use a jumper wire to bypass an open circuit.
A iumper wire is made up ot an in-line fuse
holder connected to a set of test leads. lt
should have a five amoere fuse. Never
connect a jumper wire across a short circuit.
The direct battery short will blow the fuse.
Short Finder (Short Circuit Locater)
Short finders are available to locale shorts to
ground. The short tinder creates a pulsing
magnetic field in the shorted circuit whlch you
can follow to the location of the short. lts use
is explained on page 15.
SHORT FINDER
To ordei any test equipment shown above,
contact your local tool supplier. For a list of
suppliers and tool numbers, refer to Honda
Required Special Tools and Equipment
Service Bulletin.

Troubleshooting Precautions
Before Troubleshooting
1. Check the main fuse and the fuse box.
2. Check the battery for damage, state of
charge, and clean and tight connections.
CAUTION:
. Do not quick-charge a battery unlers
the battery ground cable has been
disconnected, or you will damage the
alternator diodes.
. Do not attempt to crank the engine wlth
the ground cable disconnected or you
will severely damage the wiring.
While You're Working
1. Make sure connectors are clean, and have
no loose terminals or receptacles.
2. Make sure lhat connectors without wire
seals are packed with dielectric (silicone)
grease. Part Number: 08798-9001 .
Pack wllh dlelectrlc (sillcons) greass
When connecting a connector, push it until it"clicks" into place.
Do not pull on the wires when
disconnecting a connector. Pull
only on the connector houslngs.
Most circuits Include solid-state
devlces. Test the voltages In these
circuits only with a lo-megaohm or
higher impedance digital multlm6ter.
Never use a test light or analog meter
on chcuits that contain solld-state
devices. Damage to the devices
may result.
