The table shows the service data and their normal condition, which are displayed during the "FUNCTION DIAG." The row "Normal conditions" shows values, which are shown when each operation is made.

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 headlight automatic shutdown function. However, the headlight operation does not depend on the ignition switch positions, the scan tool does not display the title "IGNITION SWITCH".

For checking item "HI (High-beam)", the scan tool displays "OFF" on the item number 2 "Dimmer SW" when the headlights are at high-beam. Therefore, the scan tool should display "ON" momentarily when the dimmer switch is operated.

NOTE: The headlight automatic shutdown function works in approximately one second after the lighting monitor tone alarm starts sounding, and then the tone alarm ceases sounding.
