2.

Select “DATA MONITOR”.

3.

Select “START”, and confirm that other switches in malfunction-
ing system operate normally.
Example: When the auto light switch is malfunctioning, confirm
that “FRONT WIPER LOW” and “FRONT WIPER INT” in Sys-
tem 3, to which the auto light switch belongs, turn ON-OFF nor-
mally.
