1. IF THE SELECT MONITOR IS USED FOR
TROUBLESHOOTING, IT IS ADVISED TO FOLLOW
THE PROCEDURE BELOW
1) Activate function FB0 to read the most recent trouble
code and record it.
2) Activate function FB1 to read all trouble codes and
record them.
(If troubles occur in the wheel speed sensor, stop & brake
switch, valve relay or motor system, detailed data on
troubles are displayed by the FB1 function, allowing you to
easily locate points where need repair.)
3) Perform troubleshooting mainly in the FB1 mode.
