Step 6. Retest the system.

Check that the front door switch (RH) signal is
received normally.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

).

NO :

Replace the ETACS-ECU.

INSPECTION PROCEDURE N-5: The column switch (lighting, turn-signal lamp and headlamp washer
switch) signal is not received.

CAUTION

Whenever the ECU is replaced, ensure that the
input signal circuit is normal.

COMMENTS ON TROUBLE SYMPTOM
