IGNITION KEY CYLINDER
ILLUMINATION LAMP

INSPECTION PROCEDURE I-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

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

DIAGNOSIS PROCEDURE

Step 1. Check the operation of the interior lamp.
Check that the interior lamps illuminate and extin-
guish normally.

Q: Is the check result normal?

YES :

Go to Step 2.
