Diagnosis Procedure: Notes
WARNING: This page is about a different car, the 2020 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.
The IPDM E/R (intelligent power distribution module engine room) controls the tail lamp relay based on inputs from the BCM via CAN communication. When the tail lamp relay is energized, power flows through fuses 51 and 52, located in the IPDM E/R. Power then flows to the front combination lamps, rear combination lamps (body and back door side) and license plate lamps.
