i have an 01 elantra with a p1602 code from what i found the tcu communication line 1 is malfunctioning....anyone know if thats correct, whatexactly that means and how toget rid of the code??? any help would be appreciated. thanks

 

I was reading where this happens when you get a voltage drop when you disconnect the battery. You clear it with the same code reader you got the code from. Sounds like a not-to-worry thing.

 

thank you i will try it and see what happens thanks again
