check engine light trouble

[hjourney]

my check engine, "vsc off" and "vsc trac" lights are all on. I have an 01 sr5. Everything is stock besides the muffler. I have been to the shop multiple times and they thought they fixed it, but the lights come back on the next day. Can anyone help? And I have a brand new cat.

Bring it to another shop, have the read the codes. Research the codes and figure out what is wrong. What did they say the codes where for? What did they do to fix it, like what parts replaced? To me it sounds like they pulled negative cable on battery, reset ecu and sent you on your way. Now the CEL's have come back because there is something causing it to go off.

I believe the anti-lock brake sensors are tied into the VSC. Agree with the above. Disconnect the negative battery cable to clear the codes, let them reset and then find out what the code(s) are.

You can take it to most auto parts stores like Advance & Autozone and they can pull the codes for you with an OBD reader.
