For more information about diagnosis code output,
refer to the Workshop Manual.
SWS INPUT SIGNAL CHECK USING
M.U.T.-III
When the M.U.T.-III is connected to the diagnosis
connector and any of the SWS-linked switches is
operated, the PC buzzer sounds to evaluate whether
the switch is normal or not.
SWS INPUT SIGNAL CHECK AND ECU
CHECK BY USING SWS MONITOR
The switch signals sent by ECUs and the operations
of these ECUs can be confirmed by using the SWS
monitor and the M.U.T.-III.
