1996 HONDA CIVIC fuse box panel

Switch Input Test
CAUTION: Be careful not to damagc the rear window
defogger switch or the center panel when prying the
switch out.
NOTE: Before testing, check for blown No. 16 (7.5 A)
fuse in the under-dash fuse/relay box,
1. Pry the switch out of the center panel (see section 20).
2. Disconnect the 5P connector from the switch.
3. Turn the jgnition switch ON (ll), and check the voltage
between the BLVBLU {+) and the BLK (-)terminals.
There should be battery voltage
. lf there is no voltage, check for an open in the
BLVBLU wire.
. lfthere is baftery voltage, go to step 4.
Wire side of famale terminals
connect a jumper wire between the BLK/BLU and
the BLU/YEL terminals.
Turn the ignition switch ON (ll), and check that the
rear window defogger works; if it does. replace the
defogger switch.

Function Test
CAUTION: Be careful not to damage the mirror switch
or the dashboard drivel's lower covel when prying the
swhch out.
Withoui defogger:
1. Pry the switch out of the driver's dashboard lower
cover.
2. Disconnect the 10P connector from the switch.

Both inoperative:
1. check for voltage between the No. 2 (BLVYEL) ter

There should be batterY voltage
. If there is no voltage, check for:
- blown No. 17 (7 5 A) fuse in the under-dash
tuse/relay box- an open in the BLK'/YEL wire.
o lf there is battery voltage, go to step 2.
2. Check for continuity between the No 4 (BLK) termi-
nal and body ground.
There should be continuity.
. lf there is no continuity, check for:
- an open in the BLK wire.
- poor ground (G551).
Left mirror inoporalive:
connect the No. 2 {BLK/YEL) terminal of the 10P connec-
tor to the No. 3 (YEURED) terminal and the No 5 (or No
6) terminal to body ground with jumper wires The left
mirror should tilt down (or swing left) when the ignition
switch is turned ON (ll)
. lf the mirror does not tilt down (or does not swing left),
remove the left door panel. and check for an open in
the BLU/WHT (or BLU/BLK) wire between the left
power mirror and the switch
- lf the wire is OK. check the left power mirror actua-
tor.
lf the mirror neither tilts down nor swings left. repair
the YEURED wire.
lf the mirror operates properly, check the mirror switch'
Right mirror inoperative:
Connect the No. 2 (BLK /EL) terminal of the 10P connector
to the No. 3 (YEURED) terminal and the No. 9 (or No 8)
terminal to body ground with jumper wires The right mir-
ror should tilt down (or swing left) when the ignition
switch is turned ON (ll).
. lf the mirror does not tilt down (or does not swlng
left), remove the right door panel. and check for an
open in the GRN/WHT (or YEUBLK) wire between the
right power mirror and the switch.
- lf the wire is OK, check the right power marror actu-
ator.
. lf the mirror neither tilts down nor swings left. repair
the YEURED wire
. lf the mirror operates properly, check the mirror
switch.

)Control Unit Input Test ('99 - 00 models with Keyless Entry System)
1.Remove the driver's kick panel.
Disconnect the 18P connector from the control unit.
Inspect the connector and socket terminals to be sure they are all making good contacl.
. lf the terminals are bent, loose or corroded, repair them as necessary, and recheck the system
. lf the terminals look OK, make rhe following input tests at the connector.
- lf anv test indicates a problem, find and correct the cause, then recheck ihe system
- lf all the input tests prove OK, the control unit must be faulty; replace it

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.
