TROUBLESHOOTING
COMPONENT LOCATION
OPERATIONl
The horn switch always receives battery voltagevia the dedicated fuse (6) and the coil of the
horn relay.
l
When the horn switch is set to ON, the contactsof the horn relay close.
Then current flows through the dedicated fuse
(6) to the contacts of the horn relay, the hornand ground, causing the horn to sound.1. One of the horn does not sound.
TROUBLESHOOTING HINTSl Check the horn.
2. Horns do not sound.
l Check the horn switch.
l Check the dedicated fuse (6).
NOTE
(1) For vehicles equipped with the theft-alarm sys-tem, refer to
P.54-205.
(2) For information concerning the horn relay and
theft-alarm horn relay, refer to
P.54-?18.

ECU: Electronic Control Unit
NOTEIf the
lifigate unlock switch or door key cylinder unlock switch is operated roughly, or if these switches have
been installed incorrectly or switches themselves are defective the ECU may not accept the warning or alarmcancelling signal. In such case, the alarm operation will take place when the door is opened using a key.
[When the door key cylinder switch has been shorted, however, if the ignition switch is turned ON, the ECU
judges the detection-switch as faulty and thereafter, it will prevent setting of (warning) alarm until the shorting
is corrected.]
If the
liftgate is opened using a key and is left opened when the door key cylinder switch system has a trouble
(wiring harness damage, open circuit, etc.), the ECU judges it as the
liftgate holding mode and does not producealarm even when the door is opened.
