Answer
Hi
I would advice you, so you dont spend anymore money on unneeded replacement of expensive parts.
It is a pretty technical diagnosis for this code, and the switch and or encoder motor had NOTHING to do with this code.
Therefore, I would advise taking it to a GOOD electrical repair shop, or dealership and have it properly diagnosed.
Thats my advice.
I Hope it helps

PS IF you happen to want the diagnosis for this code, I'll be happy to send it along, just ASK.
