Inspection Procedure J-7
Column switches:
DNo tail lamp switch signal input to ETACS-ECU.
DNo headlamp switch signal input to ETACS-ECU.
DNo dimmer switch signal input to ETACS-ECU.
DNo passing switch signal input to ETACS-ECU.
DNo turn signal lamp left-hand switch signal input to
ETACS-ECU.
DNo turn signal lamp right-hand switch signal input to
ETACS-ECU.
Probable cause
As the (lighting) column switch input signals control the operation of the following
functions, any abnormality in the signals prevents these functions operating
normally.
DLights left ON reminder warning function
DHeadlamps, tail lamps
DTurn signal lampsDColumn switch fault
DETACS-ECU fault

Inspection Procedure J-8
Column switches:
DNo windshield mist wiper switch signal input to
ETACS-ECU.
DNo windshield wiper intermittent switch signal
input to ETACS-ECU.
DNo windshield low-speed wiper switch signal input
to ETACS-ECU.
DNo windshield high-speed wiper switch input to
ETACS-ECU.
DNo windshield washer switch signal input to
ETACS-ECU.
Probable cause
As the column switch (wiper/washer switch) input signal is used to
control the following functions, any failure prevents these functions from
operating properly.
DWindshield wiper and washerDColumn switch fault
DETACS-ECU fault
DHarness or connector fault

Inspection Procedure K-1
When the ignition switch is in the LOCK (OFF) position,
no functions work normally.
Probable cause
Checking of the ETACS-ECU battery power supply circuit
system.Probable cause
As a fault in this circuit disables ETACS-ECU functions when the ignition switch
is in the LOCK (OFF) position, any abnormality in this signal prevents the
following functions operating.
DLights left ON reminder warning function
DPower window timer function
DHeadlamp automatic cut-off function
Or, the following functions operate when the ignition switch is in the ON position
only.
DDiagnosis code reading and input signal check by MUT-II.
