2009 xc90 Changing rear tail lights to LED

Hello,
A couple of days ago , I changed all of my rear tail lights except the turn signal one over to Led's. But now I get a message on my dash that says check stop lights and bulb failure position light. Could this be because of the LED'S? They all work and I checked my high position light to see if any bulbs are burnt out but none are in that. So all lights are working and look great! But I get that message. Also could I have my service shop go in and turn that off with a tech 2?

Yes, the XC90 REM is monitoring the current consumption of the bulbs - the LED's use much less current, so set of the bulb out error. There's a board level modification you can make on the REM, or you can install "error fix resistors" to draw enough current and turn off the message. The error fix resistors even come as clamp on modules, and are the easy fix.
