SEAT BELT WARNING LIGHT

GENERAL DESCRIPTION CONCERNING SEAT BELT WARNING LIGHT

M1549023900143

The ECU related to the seat belt warning light func-
tion is as follows.

Seat belt warning light function
If any of the following conditions is met with the igni-
tion switch at "ON" or "ST", the ETACS-ECU illumi-
nates the indicator light by using the driver's seat belt
switch signal.

• The ETACS-ECU illuminates the indicator light

for six seconds if the ignition switch is turned
"ON" while the seat belt switch is on (the driver's
seat belt is not fastened).

• The ETACS-ECU flashes the indicator light 12

cycles (after 0.5 seconds) if the seat belt switch is
on (driver's seat belt is not fastened) when sixty
seconds or more have elapsed since the ignition
switch is turned "ON". One cycle consists of
five-second "on" and then three-second "off".

NOTE: The ETACS-ECU stops flashing the indicator
light immediately when the seat belt witch is off
(driver's seat belt is fastened) or the ignition switch is
turned to the "OFF" or "ACC" position while the seat
belt tone alarm function is working.
