ILLUMINATION LT-219 C D E F G H I J L M A B LT Revision: 2006 August 2006 Murano ILLUMINATION PFP:27545 System Description NKS001RP ● BCM (Body Control Module) controls illumination lamp operation. ● IPDM E/R (Intelligent Power Distribution Module Engine Room) operates illumination lamps according to OUTLINE Power is supplied at all times ● to ignition relay located in IPDM E/R, from battery direct, ● through 10A fuse (No. 71, located in IPDM E/R) ● to tail lamp relay located in IPDM E/R and ● to CPU (central processing unit) located in IPDM E/R, ● through 15A fuse (No. 78, located in IPDM E/R) ● to CPU located in IPDM E/R, ● through 50A fusible link (letter F, located in fuse and fusible link block) ● to BCM terminal 55, ● through 10A fuse [No. 18, located in fuse block (J/B)] ● to BCM terminal 42, ● through 10A fuse [No. 21, located in fuse block (J/B)] ● to combination meter terminal 21. With the ignition switch in the ON or START position, power is supplied ● to ignition relay, located in IPDM E/R, ● through 10A fuse [No. 1, located in fuse block (J/B)] ● to BCM terminal 38, ● through 10A fuse [No. 14, located in fuse block (J/B)] ● to combination meter terminal 20. With the ignition switch in the ACC or ON position, power is supplied ● through 10A fuse [No. 6, located in fuse block (J/B)] ● to BCM terminal 11. Ground is supplied ● to BCM terminal 52 ● through grounds M14 and M78, ● to IPDM E/R terminals 38 and 60 ● through grounds E13, E26 and E28, ● to combination meter 22, 23 and 24 ● through grounds M14 and M78. ILLUMINATION LAMP OPERATION When the lighting switch is in 1ST position, BCM detects the LIGHTING SWITCH 1ST POSITION (ON) by ● through IPDM E/R terminal 22 ● to CVT illumination terminal 1 ● to VDC off switch (illumination) terminal 3 (with VDC) ● to headlamp aiming switch (illumination) terminal 3 (with headlamp aiming) ● to AWD lock switch (illumination) terminal 4 (AWD models) ● to heated seat switch (driver side) (illumination) terminal 5 (with heater seat) ● to heated seat switch (passenger side) (illumination) terminal 5 (with heater seat) ● to door mirror remote control switch (illumination) terminal 16 |
