LIGHTING SYSTEM DIAGNOSIS
INTRODUCTION TO DOME LIGHT AND CARGO SPACE LIGHT DIAGNOSIS
<VEHICLES WITH KEYLESS ENTRY SYSTEM>
M1542010500519
With the dome light switch and cargo space light
switch in the "ROOM" position, the ETACS-ECU con-
trols the dome light and cargo space light operation
as follows:
• When a door is opened from outside or inside
[with the ignition switch turned to "LOCK" (OFF)]:
When a door is opened, the ETACS-ECU causes
the dome light and cargo space light to be illumi-
nated at the 100% intensity. When the door is
closed, it dims out the dome light to 65% intensity
and approximately 30 seconds later, turns out the
light completely. During this period (timer con-
trolled period), the dome light and cargo space
light goes out if the ignition switch is turned "ON"
or the doors are locked.
• When a door is opened or closed with the ignition
switch in the "ON" position: The dome light and
cargo space light illuminates at 100% intensity
when a door is opened and turned out when it is
closed.
• When no door is opened and the ignition key is
removed: When the ignition key is removed with
all the doors closed, the dome light and cargo
space light are illuminated at an intensity of 100%
and turned out approximately 30 seconds later.
During that time (time-controlled period), the
dome light and cargo space light goes out if the
ignition key inserted and turned to "ON" or the
door locking system is activated.
• Dome light's and cargo space light's answerback
operation in response to door lock control by key-
less entry system: To allow the driver to ascertain
the result of the door locking/unlocking control
action by the use of the keyless entry system, the
ETACS-ECU causes the dome light and cargo
space light to blink twice when the doors are
locked through the system and to illuminate for
approximately15 seconds when the doors are
locked. The dome light's and cargo space light's
answerback operation in response to a keyless
entry by operation of the hazard warning lights.
