Nissan Versa (N17): Parking lamp circuit

Description

The IPDM E/R (intelligent power distribution module engine room) controls the tail lamp relay based on inputs from the BCM via the CAN communication lines. When the tail lamp relay is energized, power flows through fuse 37, located in the IPDM E/R. Power then flows through the tail lamp relay to the front and rear combination lamps, license plate lamps.

Component Function Check

1.CHECK PARKING LAMP OPERATION

WITHOUT CONSULT

1. Start IPDM E/R auto active test. Refer to PCS "Diagnosis Description" (with Intelligent Key) or PCS "Diagnosis Description" (without Intelligent Key).
