VSC off, Trac Light, etc. but no check engine
I see this is a pretty common problem, but majority I have found also have check engine light on. I do not have the symptom, and the lights only come off after startup and driving a bit or reaching a certain speed or rpm. Could this still be a faulty gas cap? My code reader doesnt show anything all my other numbers it reads look fine. Any ideas would be great thanks.

Probably just needs a zero point calibration done. The below procedure is for 03-04, not sure if it's the same for newer models tho.

Is your ABS light on as well? If so, pull codes from the ABS system. Not all code readers do ABS, so you'll need one that does.

No ABS light, just vsc trac, vsc off, and traction control |
Following! Mine has the same issue, but the zero calibration didn't work.
I tried the zero calibration with a long bit of wire, and again with two paperclips. I see the quoted procedure above mentions a couple of wires. Is that significant? Do two wires need to connect the terminals, or is it suggesting having a 12 inch wire come out of each, and then connect the ends of those together? |
I must have done the zero cal a couple dozen times on my 03'. Kept coming back in a few days w no CEL. PIA
I already have the trac off switch installed (Here's the write up) for the vsc and trac, so I just leave it off now. |

This happened to me when I plugged in an off-brand OBD code reader. Or rather when I unplugged it. I just rode around with the codes for awhile because I saw the zero point calibration procedure posted here and just noped right out of it. It ended up getting fixed for free after I had my Bilsteins installed. The technician only noticed the codes after the work was done, and thought it was related to the install, so he did the zero point calibration. I can't imagine it would be very expensive to have done.
