connector A-37 <LH>, A-56 <RH> (terminal 2 <halogen

headlight> or 3 <discharge headlight>) or headlight

assembly (HIGH) connector A-38 <LH>, A-55 <RH>

(terminal 2) and headlight relay (LOW) connector A-28X

or headlight relay (HIGH) connector A-20X (terminal 3) in

good condition?

YES:

Replace the headlight assembly that does not

illuminate.

NO:

The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or

Inspection Procedure 7: The headlight automatic shutdown function does not work
normally.

M15410900099USA0000010001

Whenever the ECU is replaced, ensure that the
power supply circuit, the ground circuit and the
communication circuit are normal.

OPERATION
The ETACS-ECU operates this function in
accordance with the input signals from column switch
(lighting switch), ignition switch (IG1), and front door
switch (LH).

TECHNICAL DESCRIPTION (COMMENT)
If the headlight automatic shutdown function does not
work normally, the above described input circuits or

ETACS-ECU may have a problem. Also, it may be
possible that the headlight automatic shutdown
function is set to "Disable" through configuration
function.
