HEADLIGHT AND TAILLIGHTTaillights and headlights illumination:
Dimmer automatic reset function
The column switch (column ECU) resets the dimmer switch and prevents the high beam from lighting up when turning on the headlight again if the headlight switch is put in the "OFF" position while the high beam of the headlight is on (including the instance when the dimmer switch is erroneously put in the "ON" state upon passing operations) and resets the dimmer switch.
