Help Request Posted
2005 Hyundai Sonata GLS 2.7L MIL Lamp on, intermittently limp VIN: KMHWF35H35
U0101: Serial communication problem with TCM time out. This car is from my brother-in-laws shop. Only had time to pull code. Cust couldn't leave vehicle. Trying to find if there is a common problem. If it was a Volvo which is what I repair we would look at the CAN lines between the ECM and TCM. Thanks for any help...
