SIMPLIFIED WIRING SYSTEM (SWS)

54B-20

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 No.2 "Dimmer SW" when 
the headlights are at high-beam. Therefore, the scan 
tool should display "ON" momentarily when the dim-
mer switch is operated.
