I have a 2005 Altima in Canada with a Running Lights Module. Checked the fuses but the High beams don’t seem to work, and only the low beams seem to work.

@raezorsharp check the headlamp high relay, located in the IPDM E/R (intelligent power distribution module engine room).
“High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM (body control module) receives input requesting the headlamp high beams to illuminate. This input 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 headlamp high relay coil. When energized, this relay directs power
- to 10A fuse [No. 47, located in the IPDM]
- through terminal 24 of the IPDM
* to terminal 1 of headlamp RH, and
- to 10A fuse [No. 48, located in the IPDM]
- through terminal 22 of the IPDM
- to terminal 1 of headlamp LH.
Ground is supplied
- to terminal 2 of headlamp RH
- through body grounds E15 and E24, and
- to terminal 2 of headlamp LH
- through body grounds E15 and E24.
With power and ground supplied, the high beam headlamps and the HIGH BEAM indicator illuminate.
For proper troubleshooting check the lighting part of the FSM Altima-Lighting-.pdf which does included the Canadian lighting system
