DAYTIME LIGHT OPERATION
With the lighting switch in the OFF position and engine running, the BCM receives input signal requesting
headlamp low beam, clearance lamp, license plate lamp, and tail lamp to illuminate. This input signal is communicated
to the IPDM E/R via the CAN communication. The CPU located in the IPDM E/R controls headlamp
low relay.
l through 15A fuse (No. 41, located in IPDM E/R)
l through IPDM E/R terminal 54
l to front combination lamp RH terminal 4 (xenon type) and
l to front combination lamp RH terminal 1 (conventional type),
l through 15A fuse (No. 40, located in IPDM E/R)
l through IPDM E/R terminal 52
l to front combination lamp LH terminal 1 (xenon and conventional type).
Ground is supplied at all times
l to front combination lamp RH terminal 8 (xenon type)
l to front combination lamp LH terminal 2 (xenon type) and
l to front combination lamp RH and LH terminals 3 (conventional type)
l through grounds E21, E41 and E61.
With power and ground supplied, the headlamp low beam illuminates.
The CPU located in the IPDM E/R controls headlamp daytime light relay.

l through IPDM E/R terminal 44.
And power is supplied

Это описание принципа работы "дневного света". Посмотрел схемы...
daytime light relay. - думается, вот он корень всех светлых дел... У мну этого нет. Посему, подтвердить экспериментально не могу. Кому интересно, попробуйте это реле отключить.
