System Description: Notes
Control of parking, license plate, and tail lamp operation is dependent upon the position of lighting switch (combination switch). When lighting switch is placed in 1ST position, BCM (body control module) receives input signal requesting parking, license plate, side marker and tail lamps to illuminate. This input signal is communicated to IPDM E/R (intelligent power distribution module engine room) across CAN communication lines. CPU (central processing unit) of IPDM E/R (intelligent power distribution module engine room) controls tail lamp relay coil. This relay, when energized, directs power to parking, license plate, side marker and tail lamps, which then illuminate.
Current that flows by Rear combination lamp unit is controlled, and a tail lamp (LED) is made to turn on. Power is supplied at all times
- through 10A fuse [No. 71, located in IPDM E/R (intelligent power distribution module engine room)]
- to tail lamp relay [located in IPDM E/R (intelligent power distribution module engine room)]
- through 15A fuse [No. 78, located in IPDM E/R (intelligent power distribution module engine room)]
- to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine room)].
Power is also supplied at all times:
- through 50A fusible link (letter M, located in fuse and fusible link block)
- to BCM (body control module) terminal 55
- through 15A fuse [No. 22, located in fuse block (J/B)]
- to BCM (body control module) terminal 42
- through 10A fuse [No. 20, located in fuse block (J/B)]
- to rear combination lamp control unit terminal 1.
With ignition switch in the ON or START position, power is supplied:
- through 15A fuse [No. 1, located in fuse block (J/B)]
- to BCM (body control module) terminal 38
- through ignition relay [located in IPDM E/R (intelligent power distribution module engine room)]
- to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine room)].
With ignition switch in ACC or ON position, power is supplied:
- through 10A fuse [No. 6, located in fuse block (J/B)]
- to BCM (body control module) terminal 11.
Ground is supplied:
- to BCM (body control module) terminals 49 and 52
- through grounds M35, M45 and M85
- to IPDM E/R (intelligent power distribution module engine room) terminals 38 and 60
- through grounds E21, E50 and E51
- to rear combination lamp control unit terminal 7
- through grounds E21, E50 and E51.
