NOTE:

.

1. 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-III
screen will not be highlighted as this has nothing to do with actual lamp operation.

2. For checking item "HEADLAMP HI", the MUT-III displays "OFF" on the item No.2 "DIMMER SW" when the

headlamps are at high-beam. Therefore, the MUT-III should display "ON" momentarily when the dimmer
switch is operated.
