I immediately hooked up my bluetooth OBD scanner so I could start logging information to help driving more economically and I noticed it said "15,643 miles driven since last fault code clear." I shrugged it off until yesterday.
I stopped my car to get a drink from the store and when I turned it on, the check engine light, ABS light, traction control light, and traction control off lights all came on. Additionally, the "D" on gauge cluster was flashing. The car also would not go above 30mph. I quickly read the codes and got 2.
U0001 High Speed CAN Communication Bus
P0796 Pressure Control Solenoid 'C' Stuck On
I was 1 mile from work and decided to try to limp it there. The problem is, my work is up a hill. As soon as I got to the hill, the car wouldn't move at all. I could tell the transmission wasn't even engages. That's when a third code popped up:
P0740 Torque Converter Clutch Circuit Malfunction.
Clearly a wiring issue I thought. However, I cleared the codes and the car drove absolutely flawlessly. I drove it home after work with absolutely no problems, then drove it to work again today with no problems... until I stopped at another store to get lunch on my way to work. That's when the first two codes popped up again at start up. Same symptoms. Oddly enough, I cleared the codes again and the car drove fine to work and then back home (20 mile commute.)
Transmission fluid is clean and not burnt. It is also at the correct level.
I'm planning on bringing it the shop that my warranty is from or the dealer on Monday, but has anyone ever heard of a similar problem to this? I was a mechanic for 6 years prior to my career change, but I never really messed with transmissions. Any help would be greatly appreciated!
I would suspect the OBDII scanner you plugged in is causing the issues. I have one also and as soon as I plugged it in I got a bunch of codes. Cleared them and threw the scanner in the garbage. No further problems since. You are still under warranty so if clearing them and not plugging the scanner back in doesn't solve the problem then definitely schedule a trip to the dealer.
