I purchased a used 2012 Cabriolet last month to tow behind our Winnebago View which I had bought upon retiring last year. The car has only 25,000 miles and my wife and I are really looking forward to seeing the country with this combination.
Before having the car outfitted for towing I spent a lot of time here reading posts to determine what set up I wanted to use for towing and brakes. I ended up having a Blue Ox adapter and tow bar and a Roadmaster Invisibrake installed. The work was completed last Monday by a local RV specialist.
After towing the car back home from installing the brake system and disconnecting it from the RV I'm having a serious problem with the transmission shifting properly. On some gear changes the engine power will cut out and the transmission will not select the next gear. It happens in both D and manual mode, and even on occasion the engine will seem to cut out and the vehicle starts losing speed when cruising along at 50 mph. Though there is no check engine light I did a check with my bluetooth OBD2 device and found that there is a P0949 code: Adaptive Learning Not Done. Through all of this I have never seen the 3 bars on the display to show that it actually ever tried to learn anything and I don't see any way to actually trigger the learning myself.
Does anybody have any thoughts on what may be happening here? When installing the brake system they had the entire pan off the bottom of the car so they could access the vacuum lines and run wiring and a secondary brake light switch that is required for the Invisibrake. (I did install a battery switch on the positive terminal which is also a Roadmaster requirement for the Invisibrake). Is there a particular connector which could have been knocked loose while they were playing with the vacuum, brake switch or brake pedal area? I plan to take it back to the installer tomorrow so he can look into loose connectors but if he doesn't find anything obvious I'm not too certain he could really diagnose it further.
I looked through all the posts I could find about adaptive learning at this forum but I haven't found anything that would lead me to a solution. Is there a way for me to trigger the learn process and see it through? I've tried cycling the battery disconnect switch but restoring power always gets me back to a P or an N in the display.
Thanks for any help you can offer,
