door lock MITSUBISHI LANCER EVOLUTION 2007 Service Owner's Guide

SWS -Troubleshooting54B-30
Inspection Procedure J-6
No driver’s door lock actuator signal input to ETACS-ECU.
Probable cause
As the driver’s door lock actuator input signal is used to control the operation of
the following functions, any abnormality in this signal prevents these functions
operating normally.
DCentral lockingDDriver’s door lock actuator fault
DETACS-ECU fault
DHarness or connector fault

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.
