The rear differential warning lamp tells you if the rear differential fluid is too hot. In my case (others) and probably yours case too, it is because the wire connection has become dirty or corroded.
Tools: 180 to 220 grit sandpaper (or dremel with wire brush attachement), flashlight, paper towel. Optional: dielectric grease
Repair directions: slide under vehicle from the back (I didn't need to jack it up at all, you may want to or need to). The differential is the center section of the rear axle. On the top of the differential you will see a single wire connection. Pull the plastic wire connection off the spade. use the paper towel to clean any goo off the spade, then clean it using the sandpaper. Put dielectric grease on the connection (optional). Replace the wire connection. Your problem is solved!
If you have not changed or checked your differential fluids, you should do so. The rear dif uses a very common 80W-90 gear lube, but the front dif uses a rare type that will probably require you get it changed at subaru.

The parking light switch on top of the steering column has probably been accidentally turned on.
SOURCE: how do I replace headlight on 2006 subaru tribeca
To remove light bulb from Tribeca B9 low beam simply 1) remove outer cap, 2) reach into round cavity holding bulb and disconnect two leads, 3) then press on one end of wire clip--the one with the larger bracket (use mirror to view then go by feel) and while pressing on wire move outward away from bracket and clip will swing up and out of the way while being held from falling away by screw on other side of bulb socket. 4) pull bulb out noting that there is a tang which goes back in the same location. Driver side is easier if you remove battery. Other side only requires you remove air intake vent to air box ----- two pop-outs hold it in. Do not take the front end of the car off or light unit out as suggested above.

Hello, I know exactly what your talking about! and why no one else
did... The error code is being displayed on your trip/odo LCD screen at
the bottom of your right gauge pod if I remember correctly. Only, it\'s
not Er 66... it\'s (Er bb) which is a malfunction with your vacuum pump
system. I truly hope this is the same concern you are asking about, if
so I am happy I could help. If it is a different problem please let me
know so I can look into this matter further. I\'ve added an "error
chart guide" so you will have proof this time when/if you decide to
return to the dealer... Good luck!! and I hope this info
helps...(subytech1)...
SOURCE: We have a 2009 Subaru Tribeca with 16,000 miles
Now I am really depressed. We thought we have a change from driving Honda and Toyota so we decided to buy a new 2009 Tribeca. My first oil change for this car was 1800 miles, after breaking in. I replaced it with 7 qts of Mobile 1 Full Synthetic. Currently, the car has 8900 miles, that is 7100 driven; unfornately, I just filled 3 qts of new Mobile 1. Luckily, I check!!! Is this normal for Tribeca? If so, this is the worst investment of a lifetime. I won't ever buy Subaru again or recommend to anyone!!!
