System DescriptionEKS007AB
Daytime light system turns on daytime light lamps while driving. Daytime light lamps are not turned on if
engine is activated with parking brake applied. Release parking brake to turn on daytime light lamps. The
lamps turn off when lighting switch is in the 2ND position or AUTO position (Headlamp is "ON") and when light-
ing switch is in the PASSING position. (Daytime light lamps are not turned off only by parking brake itself.)
A parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line.
OUTLINE
Power is supplied at all times
through 10A fuse [No. 19, located in the fuse block (J/B)]
to combination meter terminal 8, and
through 50A fusible link (letter f , located in the fuse and fusible link box)
to BCM terminal 70, and
through 10A fuse [No. 45, located in the IPDM E/R (intelligent power distribution module engine room)]
to daytime light relay terminals 2 and 5.
When the ignition switch is in ON or START position, power is supplied
through 10A fuse [No. 14, located in the fuse block (J/B)]
to combination meter terminal 24, and
through 10A fuse (No. 59, located in the fuse and relay box)
to BCM terminal 38.
Ground is supplied
to combination meter terminal 17 and
to BCM terminal 67
through grounds M57, M61 and M79.
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, the IPDM
E/R receives input requesting the daytime lights illuminate. This input is communicated across the CAN com-
munication lines. The CPU (central processing unit) of the IPDM E/R controls the daytime light relay coil.
When energized, this relay directs power
through daytime light relay terminal 3
to front combination lamp LH terminal 2
through front combination lamp LH terminal 6
through IPDM E/R terminal 55
through 10A fuse (No. 35, located in the IPDM E/R)
through 10A fuse (No. 34, located in the IPDM E/R)
through IPDM E/R terminal 56
to front combination lamp RH terminal 6.
Ground is supplied
to combination lamp RH terminal 2
through grounds E9, E15 and E24.
With power and ground supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
AUTO LIGHT OPERATION
For auto light operation, refer to LT-4 8, "System Description" in AUTO LIGHT SYSTEM.
CAN Communication System DescriptionEKS007AC
