(See MUT-II Reference Manual or MUT-III Instruction Manual)

(2) The following ECU checks can be performed when the ECU is connected to the MUT-II/III and the SWS monitor.

Note: 
If an abnormality arises during ECU checking, then troubleshooting should be performed by referring to the Inspection
procedures classified by trouble symptoms.
(See p.54B-21)

5. Service data check service points

(1) The service data is checked using the MUT-II/III and the SWS monitor.

A service data check performed using the SWS monitor only relates to the signals present on the SWS communications
line and the door-to-door communications line. For information on the input signals which are not checked by the SWS
monitor, refer to the Pulse check service points (MUT-II/III or voltmeter) p.54B-20.

(2) The following input signals can be checked when the MUT-II/III and SWS monitor are connected.

Note: 
If an abnormality arises during service data checking, then troubleshooting should be performed by referring to Confirming
problems in input signal check (Service data, Diagnosis by Function, or pulse check). (See p.54B-24)
