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 

− How to Use Troubleshooting/Inspec-

tion Service Points 

− Diagnosis Function 

P.00-7

).

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
