IGNITION KEY CYLINDER ILLUMINATION LAMP CONTROL FUNCTION

The ETACS-ECU controls the ignition key cylinder
illumination lamp and foot lamp as described below.

1. The ignition key cylinder illumination lamp and for

30 seconds when the driver's door is
opened/closed with the ignition switch OFF.

2. Also when the ignition key is removed from the

ignition key cylinder, the lamp illuminates for 30
seconds.

3. When the ignition key cylinder illumination lamp

is operating with the doors closed, it goes out if
the ignition switch is turned ON.

DOOR-AJAR INDICATOR

The ETACS-ECU sends the open/close status of
each door to the combination meter through CAN
communication. The combination meter receives the
transmitted signal and turns ON and OFF the
door-ajar indicator. The door-ajar indicator flashes
when the door-ajar warning function is activated
while the door-ajar indicator is ON (For more infor-
mation about the door-ajar warning function).

HOW TO READ DIAGNOSIS CODE

Use the M.U.T.-III to read diagnosis code (Refer to
GROUP 00

tion Service Points

− Diagnosis Function

).

NOTE: Connect the M.U.T.-III to the 16-pin diagnosis
connector (black).
NOTE: A diagnosis code can not be read when the
ETACS-ECU is defective or the power supply voltage
has risen. In this case, refer to inspection procedure
