Daytime Light Operation
WARNING: This page is about a different car, the 2008 Infiniti M45 and 2008 Infiniti M35. However, it is still accessible from the selected car via links, so may be relevant.
With the engine running, the lighting switch in the OFF or AUTO position (headlamp is not illuminate) and parking brake released, the IPDM E/R receives input request signal from BCM to turn on daytime light. This input is communicated across the CAN communication lines. The CPU of the IPDM E/R controls the daytime light relay coil. When energized, this relay directs power
- through daytime light relay terminals 5 and 3
- through front combination lamp RH terminal 2
- through front combination lamp RH terminal 6
- through IPDM E/R terminal 27
- through 10A fuse (No. 72, located in IPDM E/R)
- through 10A fuse (No. 74, located in IPDM E/R)
- through IPDM E/R terminal 28
- to front combination lamp LH terminal 6.
Ground is supplied
- to combination lamp LH terminal 2
- through grounds E22 and E43.
With power and grounds supplied, the daytime lights illuminate. The high beam headlamps are now wired in series and illuminate at a reduced intensity.
