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.

CHECKING THE CIRCUIT AND INDIVIDUAL PART1. ETACS POWER-SUPPLY AND GROUND CIRCUITS
Description of operationThe battery supplies a stabilized 5 V power supply to the
ECU, via the constant-voltage circuit and terminal 51 (which
is directly connected to the battery).

Description of operationThe key-reminder switch is switched OFF and HIGH-level
signals are sent to the ECU when the key is inserted into
the ignition key cylinder: when the key is removed, the key-re-
minder switch is switched ON and LOW-level signals are sentto the ECU.
