6. Pulse check service points (MUT-II/III or voltmeter)
(1) A pulse check is used to inspect input signals which cannot be inspected on the SWS monitor using the MUT-II/III or
voltmeter (input signals which are not present on the communications line).
(See Chapter 00, How to Use Troubleshooting and Inspection Service Points.)
(2) The following input signals are checked in this state.
Note :
If a problem arises in the pulse check, 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).
Switches and conditions for performing pulse check
7. MUT-II/III flight recorder function
(1) It is possible to store communications data for ECU checks, service data and function-based diagnosis in a memory in the
SWS monitor cartridge. The stored communications data can be reproduced on a chart or graph display.
(2) If data is stored for a long time by means of the flight recorder function, then in order to reduce vehicle battery
consumption, it is possible to remove the MUT-II/III with the data stored in the SWS monitor cartridge.
Note :
For details of the MUT-II/III flight recorder function, see the MUT-II Reference Manual or MUT-III Instruction Manual.
