- Lighting switch AUTO (auto light function ON judgment)
- Lighting switch AUTO, with the front fog lamp switch ON and the ignition
switch ON
IPDM E/R turns the integrated headlamp low relay ON, and turns the headlamp ON according to the low beam request signal.
HEADLAMP (HI) OPERATION
BCM transmits the high beam request signal to IPDM E/R and the combination meter using CAN communication according to the headlamp (HI) ON condition. At this time, BCM stops to transmit low beam request signal.
Headlamp (HI) ON condition
- Lighting switch HI with the lighting switch 2ND or AUTO (auto light function
ON judgment)
- Lighting switch PASS
- Lighting switch AUTO, with the front fog lamp switch ON, the ignition switch
ON and lighting switch HI.
Combination meter turns the high beam indicator lamp ON according to the high beam request signal.
IPDM E/R turns the integrated headlamp high relay ON, and turns the headlamp ON according to the high beam request signal.
FOLLOW ME HOME FUNCTION
When the driver is moving to the house entrance from the own vehicle, headlamp is kept still ON by the follow me home function of BCM.
When BCM detects the input of lighting switch PASS while all of following conditions satisfied, it transmits the low beam request signal for a period of time to IPDM E/R through CAN communication.
Follow me home ON condition

IPDM E/R turns the integrated headlamp low relay ON, and turns the headlamp ON according to the low beam request signal.
When in any of following conditions, follow me home function can be cancelled while follow me home function is operating.
Follow me home OFF condition - Ignition switch is turned from OFF→ACC or ON - Lighting switch is turned from OFF→ON
NOTE
:
Flash-to-pass operation illumination time for 1 time can be extended to
approximately 30 seconds during
operation of follow me home function.
Flash-to-pass operation can be illuminated continuously for approximately 60 seconds (flash-to-pass operation, 2 times), approximately 90 seconds (flash-to-pass operation, 3 times), and a maximum of approximately 120 seconds (flash-to-pass operation, 4 times).
