COMMENTS ON TROUBLE SYMPTOM
The system may be at fail-safe mode as the SWS
communication line is defective. If the front-ECU
does not receive the ignition switch (ACC) signal due
to an open circuit in the SWS communication lines or
other reasons when the ignition switch is at the ACC
position, the system will enter the fail-safe mode.
POSSIBLE CAUSES
•
Malfunction of the column switch
•
Malfunction of the front-ECU
•
Damaged harness wires and connectors
DIAGNOSTIC PROCEDURE
Step 1. Check the diagnosis code.
When the ignition switch is turned to the LOCK
(OFF) position, check that the ETACS-ECU does not
set the diagnosis code.
Q: Is the diagnosis code set?
YES :
Refer to diagnosis code chart
NO :
Go to Step 2.
Step 2. Pulse check
Check the input signals below which are related to
the windshield wiper.
OK: The MUT-II/III sounds or the voltmeter
needle fluctuates.
