SERVICE DATA CHECK
  1. Use the MUT-II/III and the SWS monitor to check "Service Data."
    This "Service Data" check is applicable for signals, which are transmitted and received through the SWS communication line and the communication lines routed from one door to another. For the input signals which are not applicable for the SWS monitor check, refer to pulse check procedure
    .
  2. NOTE: If a problem is found in the "Service Data" check, refer to the Problems during Input Signal Check <Service data, function diagnosis or pulse check> (Refer to ).
  1. The following input signals can be checked by using the MUT-II/III and the SWS monitor.

NOTE: When checking the input signals (off, tail, low-beam or high-beam), turn the ignition switch to the "ON" position in order to disable the headlamp automatic shutdown function. However, the titles on the MUT-II/III screen will not be highlighted as this has nothing to do with actual lamp operation.
For checking item "HI (High-beam)", the MUT-II/III displays "OFF" on the item No.2 "Dimmer SW" when the headlamps are at high-beam. Therefore, the MUT-II/III should display "ON" momentarily when the dimmer switch is operated.
