Powertrain and Check engine light is on
 

Hey everyone yesterday while driving my powertrain light came on and then my check engine light as while. this all happen when i was taking my car out of cruise control. and now my cruise control nor my sport mode will work in my car. the car takes a while to accelerate while driving.
so i went to autozone and they gave me a code:
P1643
P1111

i just had my car tuned up for its 80,000 2weeks ago.

is there something that i can do myself besides taking it back to the dealership

P1111 just means that the car has finished running its checks when you turn on the ignition
P1643 is a CAN ECM/TCM network malfunction on at least 2 consecutive trips and is caused by anyone of these faults which means its either a short circuit,the transmission control module or the engine control module:-

• CAN open circuit fault – TCM to ECM
• CAN short circuit fault
• TCM failure
• ECM failure

When this fault code is triggered the car automatically outs the ECM into a safety default mode meaning

• – Speed control inhibited
  
• – Maximum throttle opening for N range inhibited
  
• – Throttle opening limited to 30%
  
• – Maximum engine speed reduced

Probably needs a good auto-electrician if theres a short circuit otherwise a specialist or dealer I would guess??
