i was driving like how i usually do when all of a sudden i get a CEL and Engine Code U0155. Can anyone tell me what the code is for?

 

Greetings from nearby Napa.

Well, I have just received the service manual but I could not find the codes in there. I need to be more familiar. Sorry :-(

 

I believe its OBD2 Lost Communication With Instrument Panel Cluster (IPC) Control Module

 

I checked my diagnostics on my nav and the message I got was/ still is "Engine System U0155. Engine may not operate properly. Acceleration may be reduced." I wish the diagnostics would be more specific. And another thing I noticed after I got the CEL was that downshifting during braking was pretty jerky. Could that be a seperate problem? Any other TL-S owners that have had a similar problem?

 

are you trying to solve this problem yourself?

why not take it into dealer for warranty work if it is under warranty???
