Hi,

Because of the complexity of this vehicle, I recommend having the can-bus scanned because many things can cause the vehicle to be in limp mode. CAN stands for controller area network.

Basically, all the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them.

Here is a link that shows how it's done:

That is where I would start. However, I don't know if you have already tried this or had the computer scanned. If you have, let me know if there are codes stored or anything that you feel may be helpful for me.

Let me know.
