I just recently bought a 2007 Lexus Rx 350 drives great. Only code that came up before purchase was a traction control (VSC) which is not that big of a deal. I take it to get smogged and it failed. The report says check engine light has been tampered with because it doesn’t come on at all. I had a mechanic take a look and he pulled out the cluster and it didn’t look like anything was amiss. There is no actual bulb it’s just a circuit board. All the wires are intact. He was baffled as to how someone could have made it to where only the check engine light doesn’t come on. Every other light works. Can anyone give me any input? TIA.
