Nissan Maxima Service and Repair Manual: Headlamp (LO) circuit
Description
The IPDM E/R (intelligent power distribution module engine room) controls the headlamp low relay based on inputs from the BCM over the CAN communication lines. When the headlamp low relay is energized, power flows through fuses 51 and 52, located in the IPDM E/R. Power then flows to the front combination lamps to the headlamp low beam.
Component Function Check
1.CHECK HEADLAMP (LO) OPERATION
WITHOUT CONSULT
- Start IPDM E/R auto active test. Refer to PCS-11, "Diagnosis Description".
- Check that the headlamp is turned ON.
NOTE: HI/LO is repeated 1 second each when using the IPDM E/R auto active test.

enough for HomeLink to pick up the signal
during training. Similar to this Canadian law,
