Cornering Lamp: Description and Operation

System Description

OUTLINE
Power is supplied at all times
- through 50 A fusible link (letter f, located in the fuse and fusible link box)
- to BCM (body control module) terminal 55, and
- through 10 A fuse [No. 21, located in the fuse block (J/B)]
- to BCM terminal 42, and
- through 15 A fuse [No. 34, located in the IPDM E/R (intelligent power distribution module engine room)]
- to the CPU (central processing unit) in the IPDM E/R, and
- through 15 A fuse (No. 41, located in the IPDM E/R)
- to cornering lamp relay LH and RH.

CORNERING LAMP OPERATION
When the ignition switch is in the ON or START position, power is supplied
- to ignition relay, located in the IPDM E/R, and
- through 10 A fuse [No. 1, located in the fuse block (J/B)]
- to BCM terminal 38.

Ground is supplied
- to BCM terminal 52
- through grounds M57, M61 and M79, and
- to IPDM E/R terminals 38 and 60
- through grounds E15 and E24.

LH Turn
When the lighting switch is in the 2nd position or in the AUTO position (headlamp ON) and turn signal switch is moved to the left position, BCM sends signal through CAN communication lines to IPDM E/R. IPDM E/R then operates cornering lamp relay LH. It sends power from IPDM E/R terminal 34 to cornering lamp LH terminal +.

Cornering lamp turns on
- through cornering lamp terminal -
- to grounds E15 and E24.

RH Turn
When the lighting switch is in the 2nd position or in the AUTO position (headlamp ON) and turn signal switch is moved to the right position, BCM sends signal through CAN communication lines to IPDM E/R. IPDM E/R then operates cornering lamp relay RH. It sends power from IPDM E/R terminal 23 to cornering lamp RH terminal +.

Cornering lamp turns on
- through cornering lamp terminal -
- to grounds E15 and E24.
