1999 Lexuus ES300 VSC, VSC Off & Engine Light
 

I am having the VSC, VSC_Off & Engine lights on for over a month now and I have continued to drive it without a problem. A couple years ago I had same exact problem and my code reader pointed to one of the coil cables. I replaced it and fault lights went away. This time around, my code reader does not read any codes. I have over 11V at the vehicles DLC connector. When I connect my code reader to the vehicle, it says "auto_link in progress" an then the code reader unit shuts down. The code reader itself w/ fresh batteries is OK because I tested it on my other cars and it connects and reads codes fine with no problems. Would someone please comment or provide help.

Thank you.
