DIAGNOSIS CODE INSPECTION PROCEDURES
Code No.11 Failure concerning the ETACS-ECU
The ETACS-ECU monitors its own communication data, and sends a diagnosis
code when an error takes place consecutive fifteen times in 0.6 second.
The diagnosis code will be erased when the ETACS-ECU determines that its
own communication data is sent consecutive 15 times in 0.6 second.
Replace the ETACS-ECU.
Code No.12 Failure concerning the column switch or
improper connection with the ETACS-ECU
This diagnosis code is displayed when the column switch sends a signal
regardless of the transmission request signal from the ETACS-ECU (three times
or more in one second).
The diagnosis code is erased when the column switch continues to send a
signal according to the transmission request signal from the ETACS-ECU for
one second.
