1998 HONDA CIVIC codes

Chocking th€ Diagnostic Trouble Code (DTCI
with the Servico Check Conneqtor and Sp€cialTool
When the PCM senses an abnormality in the input or output systems, the @ indicator light in the gauge assembly will blink
When the Service Check Connector (locat€d under the dash on the passengsr side) is connected with the special tool as
shown, the E indicator light will blink the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON (ll).
When the E indicator light has been reported on, connect the Service Check Connector with the special too'.
Then turn ON (ll) the ignition switch and obssrve the E indicator tight.

Codes 1 through 9 are indicated by individual short blinks, Codes 10 and above are indicat€d by a sories of long and short
blinks. One long blink equals 1O short blinks. Add the long and short blinks together to determine th€ code. After deter-
mining the code, refer to the electrical system Symptom-to Component Chart on pages 1+52 and 1+53 for'96 - 98 mod-
els, and 14-54 and 14-55 for the '99 - 00 models.

Five-step Troubleshooting
2.
1.Verify The Complaint
Turn on all the components in the problem circuit to
verify the customer complaint. Note the symptoms.
Do not begin disassembly or testing until you have
narrowed down the problem area.
Analyze The Schematic
Look up the schematic for the problem circuit.
Determine how the circuit is supposed to work by
tracing the current paths from the power feed
through the circuit components to ground. lf several
circuits fail at the same time, the fuse or ground is a
likely cause.
Based on the symptoms and your understanding of
the circult operation, identify one or more possible
causes of the problem.
lsolate The Problem By Testing The Circuit
Make circuit tests to check the diagnosis you made
in step 2. Keep in mind that a logical, simple proce-
dure is the key to efficient troubleshooting. Test for
the most likely cause of failure first. Try to make
tests at points that are easily accessible.
Fix The Problem
Once the specific problem is identified, make the
repair. Be sure to use proper tools and safe proce-
dures.
Make Sure The Circuit Works
Turn on all components in the repaired circuit in all
modes to make sure you've fixed the entire prob-
lem. lf the problem was a blown fuse, be sure to
test all of the circuits on the fuse, Make sure no new
problems turn up and the original problem does not
recur.

Wire Color Codes
The following abbreviations are used to identify wire
colors in the circuit schematics:
wHT ............................. White
YEL ............................... Yellow

GRY .............................. Gray
PUR .,.................,.,........ Purple
LT BLU ......................... Light Blue
LT GRN ........................ Light Green
The wire insulation has one color or one color with
another color stripe. The second color is the stripe.

-Starter Test
NOTE; The air temoerature must be between 59 and
100'F (15 and 38"C) before testing.
Recommended Procedure:
. Use a staner system tester.
. Connect and operate the equipment in accordance
with the manufacturer's instructions.
. Test and troubleshoot as described,
Alternate Procedurg:
. 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.
NEGATIVETERMINAL
NOTE: After this test, or any subsequent repair. reset
the ECM/PCM to clear any codes (see section l1)
Check the Start€r Engagemont:
1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box,
2. Turn the ignition switch to START (llll with the shift
lever in E or E position (rVT) or with the clutch pedal
depressed {M/T). The starter should crank the engine.
. lf the starter does not crank the engine, go to
step 3.
. lf itcranksthe engineerraticallyortooslowly, go
to "Check for Wear and Damage" on the next
page.
Check the battery. battery positive cable, ground,
starter cut relay, and the wire connections for loose-
ness and corrosion, Test again.
lf the starter still does not crank the engine, go to
step 4,
Unplug the connector (BLK,/WHT wire and solenoid
terminal) from the starter,
Connect a jumper wire from the battery 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 startercranksthe engine, goto step 6.
Check the ignition switch (see page 23-891.
Check the starter cut relay and clutch interlock switch
(see page 23-86,87).
Check the A/f gear position switch (see page 23-154).
Check for an open in the wire between the ignition
switch and starter.

Storing Transmitter Codes
. The codes of up to four transmitters can be stored in the control unit. {lf a {ifth code is stored, the code which was
stored tirst will be erased.)
. When the system enters the registration mode, all previously slored codes will be erased.
. The system leaves the registration mode and returns to the normal mode if you
- turn the valet swirch OFF, or
- turn the ignition switch OFF, or
- do not press the transmitter button for more than 10 seconds
Procedure:
NOTE: lt is important to maintain the time limits between steps
VALET SWITCH
NOTE: lf the tuner is turned ON, it willgo off and come on again when the reg-
istration procedure is completed-

NOTE: lf you want to register the codesof more than one transmitter, repeat step4 within 10 seconds with the next trans'mitter.
NOTE: After storing its code, make sure
the transmitter works properly bYrepeatedly pressing one ot its buttons.(The system starts to work when Youpress any transmitter button six times-)

Storing transmitter codes;
The codes of up to three transmitters can be read into
the keyless receiver unit memory. (lf a fourth code is
stored, the code which was input first will be erased.)
NOTE: lt is important to maintain the time limits
between the steps.
'1. Turn the ignition switch ON (ll).
2. Within 1 to 4 sec., push the transmitter lock or unlock
button with the transmitter aimed at the vehicle.
3. Within I to 4 sec., turn the ignition switch OFF.
4. Within 1 to 4 sec., turn the ignition switch ON 1ll).
