Hello,
Our 2008 Tribeca (5passLTD - now 60,000mi) now has the R.Diff Temp light randomly lighting up on the dashboard. It flickers and changes intensity making me believe that this is a ground problem with the sensor.
I think I would check the level of fluid first, and if it hasn't been changed in a while or never been changed, I would do that first and see if that wouldn't correct the problem........not saying it is not a sensor or a short, I just try and do the easy things first.....
Recently had the same problem. Turns out the sensor on the rear diff had corrosion on it. Unplugged it, cleaned it off, plugged it back, R.Diff Temp light now out.
i had the same problem with my 06 it turn out to be the black ground wire right below the diff sensor had corrosion. take a sand paper and clean the plug and that should fix it..
Thanks to all who posted about the flickering R. DIff Temp Warning light.
Mine just starting coming on at 102,000 KM - but I think it may have something to do with driving through some door level snow banks over the weekend. I'll check to see if the connection is lose before doing anything else/
Had this same problem on friday. Looked under the car and found that the black ground wire connected to the diff had rotted through. Couldn't salvage the connector so i had to MacGyver a splice in and used a blue spade connector. Heat shrunk all the wires and the connection to the diff and filled the connector with dielectric grease. Hope my fix works as it is probably a $400 plus fix at the dealer.
Sigh, why is it they need to make these things so darn inacessable?
I will post as to how my fix works down the road...
For those of you who are experiencing the R Diff Temp light coming on; Do you notice the car stuttering when the light flickers?
I have a 2007 Tribeca and when the light flickers on, the care seems to stutter upon acceleration.
We are going to be pulling a tent trailer next week and wondering if it's going to hurt anything if we don't get the problem nailed down by then. Thanks for your input.
But I know that I would take care of it if this is happening more than once. Also I would make sure the car has all the required maintenance done as per schedule and especially all the fluids were changed.

Thanks. It's been about 8 months since our 50k mile service was performed. So, I brought the car to the dealer last night and they'll be working on it today. We have an extended (10yr/100k) warranty so I'm hoping whatever it is will be covered.
Just got it back from the dealer. They simply checked levels, pulled the connectors, cleaned them, added fresh dialectic grease and test drove it under load for about 25 miles. They told us to bring it back if the problem returns.
Turned out to be a faulty ground on the sensor part. They rewired it. In addition to winter conditions, we do our share of off road on our weekly trips to the cottage. The light reappeared (along with ABS, Traction and Cruise) when we drove into a large puddle. It appears that the computer was receiving fault signals from the transmission. We cleaned and sealed the transmission wires as well (as some water infiltration was causing the ground faults).
Okay, found the sensor and have the manual.
However, with the exhaust pipe running right by, I'm having a heck of time determing how to take the sensor off (and I cant find anything in the manual specific to this). I'll give it another shot soon, but why does a 5 minute job always turn into a 2 hour excursion for me?
Ah crap, so I managed to get the sensor off, sprayed with with sensor clean, added some dialectic grease and the warning light is still on. Must be a physical issue with the wire.
Looks like I'll need to bring it in to the dealership and try to convince them the problem is in the sensor and not the fluid.
