2002 HONDA CIVIC fuses

IVehicle Speed Signal Circuit Troubleshooting
Special Tools Required:
Test Harness 07LAJ-PT3020A
Before testing, inspect the No. 4 (10A) and No. 10 (7.5A)
fuses in the under-dash fuse/relay box.
1. Disconnect the 3P connector from the vehicle
speed sensor (VSS) {A).
Connect the test harness only to the engine wire
harness.
Connect the RED test harness clip (B) to the positive
probe of an ohmmeter. Cover the white (C) and
green {D) test harness leads with protective tape (E).
Check for continuity between the RED test harness
clip and body ground,
ls there continuity?
YES Go to step 5.
NO Repair open in the BLK wire between the VSS
and G 101.I
3.
4.
5. Connect the WHT test harness cliD (B) to the
positive probe of a voltmeter, and connect the RED
test harness clip (C) to the negative probe.
Turn the ignition switch ON (ll).
le thara h2ltarv v^ltada?
YES-Go to step 7.
NO Repair open in the BLK,/YEL wire between the
VSS and the under-dash fuse/relay box.l
Disconnect the WHT test harness clip (B).
Connect the GRN test harness clip {D) to the
positive probe of a voltmeter.
Is there 5 V or more?
YES- Go to step 9.
NO Repair short or open in the BLUMHT or WHT/
GRN wire between the VSS and the cruise control
unit, or the ECM.I

Multiplex Control System
Troubleshooting
Mode 1 Tset
1. Remove the driver's dashboard lower cover {see
page 20-59).
2. Check the No. 9 ( 10A) fuse in the under-hood fuse/
relay box and the No. 10 (7.5A) fuse in the under-
dash fuse/relay box.
Are the fuses OK?
YES-Go to step 2.
NO-Find and repairthe cause ofthe blown fuse.!
3. Turn the ignition switch ON (ll).lf the driver's
seatbelt is unbuckled the seat belt reminder will
chime 6 times.
4. Set the ceiling light to the center position and close
allthe doors.
5. Connect the specialtoolto the multiplex inspection
conneclor.
6. After about 5 seconds the spotlight and ceiling light
should come on for 2 seconds, go out, then blink on
for 0.2 second to show the system is now in mode
1.
Did the spotlight and ceiling light indicate mode
1?
YES-Go to step 8.
NO Go to step 7.

-
7. Check for continuity between terminal 4ofthe
under-dash fuse/relay box connector J and body
ground.
ls there continuity?
YES Replace the under-dash fuse/relay box.l
NO - Repair the open in the wire.lf the wire is ok,
repair G301.1
8. lf ther are any DTCS present, the spotlight and
ceiling light will blink to indicate the DTC(S). lf more
than one DTC is present, the DTCS will be displayed
in ascending order, lf there are no DTCS the
spotlight and ceiling light will not blink again after
the mode 1 indication.
Are there any DTCg?
YES Go to step 9.
NO Go to the Mode 2 test.
9. Troubleshoot the DTC(S) in the order indicated
using the following charts.
lf a faulty control unit is suspected, substitute it
with a known food part and recheck for DTCS,
. lf the DTC(s) isstill present. go to the next step
listed for the DTC.. lf the DTC(S) is no longer present replace the
original part.
