turn signal MITSUBISHI LANCER EVOLUTION 2007 Service Workshop Manual

SWS -Troubleshooting54B-31
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
DHarness or connector fault
NG
Replace ETACS-ECU.
NO
Replace column switch.Check the trouble symptoms.
OK
MUT-II diagnosis code
When the ignition switch is in the LOCK (OFF) position, is the
diagnosis code output?YESDiagnosis Code Chart (Refer to P.54B-3).
Check the (lighting) column switches (Refer to GROUP 54A).NG

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
NG
Replace ETACS-ECU.
NO
Replace column switch.Check the trouble symptoms.
MUT-II diagnosis code
When the ignition switch is in the LOCK (OFF) position, is the
diagnosis code output?YESDiagnosis Code Chart (Refer to P.54B-3).

*
Y0795AU
NOTE
*See the list below for data on the ETACS-ECU terminal 1 - 20 connectors. As the ETACS-ECU connects
directly onto the junction box, the voltages cannot be measured.
