DIAGNOSIS CODE SET
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.

NOTE: .
•− shown in the table indicates that the check item for the input of the corresponding signal is not present in
M.U.T.-III.
•*1Checking the input signal by the sound of the buzzer is not possible. Input signal must be checked on
the M.U.T.-III display.
•*2: Buzzer sound during the check is triggered by the input signal from the ignition switch. It is not to check
the presence of the power window switch acceptance permission signal.
•*3: Buzzer sound during the check is triggered by the input signal from the keyless entry transmitter. It is
not to check the presence of the multimode keyless entry input signal.
