Galant V6-3.0L SOHC (2003)
If the column switch sends a headlight switch "ON" signal to the front-ECU, the front-ECU turns on its headlight relay (LOW), causing the low-beam
headlights to illuminate. If the dimmer switch is turned on while the headlight relay (LOW) is on, the front-ECU turns on the headlight relay (HIGH),
causing the high-beam headlights to illuminate.
If the acknowledgement signal, which the front-ECU sends to the SWS communication line, turns to "HI-BEAM ACK", or the headlight switch signal,
which the column switch (column-ECU) sends to the SWS communication line, turns to "PASSING", the ETACS-ECU will illuminate the high-beam
indicator light.
NOTE: This description covers the headlights only. In actual driving, the headlights may be turned off due to the headlight automatic shut-down
function. For the details of the headlight automatic shut-down function, refer to its Section.
Headlight automatic-shutdown function
Even if the lighting switch (tail light switch or headlight switch) is ON, the head light (including the tail lights) will automatically go off in the following
conditions to prevent the battery from discharging as a result of forgetting to turn off lights.
When the ignition key is turned from "ON" to "LOCK" (OFF) or "ACC" position with the lighting switch turned ON, and this state continues for three
minutes, the light will automatically be turned off. If the driver's seat door is opened during these three minutes, the light will go off one second later.
NOTE: This function can be disabled by the configuration function.
Dimmer automatic reset function
If the headlight switch is turned off while the high-beam headlights are on, the dimmer switch will be reset. Because of this,the headlights will illuminate
at low beam when they are turned on at next opportunity. The dimmer switch will be also reset if the dimmer switch is turned on unintentionally while
the passing switch is operated.
