The Check Engine Light in my 2000 Toyota Tundra came on while driving down the interstate the other day. The vehicle continued to run fine and there were no other signs that something was wrong (the truck still starts up and runs fine in the days since). When I got home I plugged in my code reader (a cheapy Ancel AD310) and received a link error. The reader gets power and turns on, just won’t communicate with the vehicle. I checked the code reader on my 2011 Subaru Forester to confirm that it was working and it had no problem connecting to that vehicle. I checked the OBD fuse and the ECU fuses and all looks good. I tried going to Advanced Auto to try a different code reader but due to the pandemic they are no longer checking CELs.
Other then get my hands on another code reader, I’m at a bit of a loss as to how to diagnose this problem. I have seen a few posts about this on other forums but nothing that pertains to my specific issues that had information on a successful resolution. Thanks in advance to everyone for their help and advice!
