System Description: Notes

Control of the parking, license plate, and tail lamp operation is dependent upon the position of the lighting switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM receives input signal requesting the parking, license plate, side marker and tail lamps to illuminate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The central processing unit of the IPDM E/R controls the tail lamp relay coil. This relay, when energized, directs power to the parking, license plate, side marker and tail lamps, which then illuminate. Power is supplied at all times

• to tail lamp relay, located in the IPDM E/R (intelligent power distribution module engine room)
• through 10A fuse [No. 75, located in the IPDM E/R (intelligent power distribution module engine room)].

  Power is also supplied at all times

• to BCM (body control module) terminal 7
• through 40A fusible link (letter F, located in the fuse and fusible link box).

  With the ignition switch in the ON or START position, power is supplied

• to BCM (body control module) terminal 35
• through 10A fuse [No. 1, located in the fuse block (J/B)].

  With the ignition switch in the ACC or ON position, power is supplied

• to BCM (body control module) terminal 36
• through 10A fuse [No. 6, located in the fuse block (J/B)].

  Ground is supplied

• to BCM (body control module) terminal 8
• through grounds E17, E43 and F152.
