Just started getting this message, maybe three times now. Restart 04 CTT and it disappears. I realize the transmission servo motor can be the culprit as well as a low battery. My battery was replaced at purchase in June, and the 4WD transfer case was replaced in 05 under warranty. I've never used the 4wd or locked into low gear or used the locking diffs until today. I put it in neutral and could not get the rear diff to lock; pulling the switch to the rear simply did nothing and the transmission icon did not illuminate the rear differential. Center and low/ front was illuminated.

While in there I'm investigating my crummy idle after I start the car.

Anyone replace a servo motor lately? Buy from Sonnen or Suncoast? Thanks guys.

Are you sure you have the rear differential lock option? Cold temps can cause this fault but it's all guess work without reading the fault codes.

Battery is at 12v even and its new in June of 11 at purchase. Gotta replace it.

Coils were cleaner and fresher than anything I've seen in an engine before and they were new in 06 under warranty.

Fuel pressure is STRONG.

I still have a stumble after starting the car which gets better but not fully.

Daaaaang.
