The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Repair the wiring harness.

Step 8. Connector check: A-11X front-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 9.

IGNITION KEY CYLINDER 
ILLUMINATION LAMP

INSPECTION PROCEDURE G-1: The ignition key cylinder illumination lamp does not 
illuminate/extinguish normally.

CAUTION

Whenever the ECU is replaced, ensure that the 
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM

The ETACS-ECU operates this function in accord-
ance with the input signals below.

• Ignition switch (IG1)

• Key reminder switch

• Driver's door switch

• Interior lamp loaded signal

If this function does not work normally, these input 
signal circuit(s), the ignition key cylinder illumination 
lamp or the ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the key reminder switch

• Malfunction of the driver's door switch

• Malfunction of the ignition key cylinder illumina-

tion lamp

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors
