I have a 2003 Tahoe Z71 and if I shine a flashlight in the instrument cluster I can see that I have a TPMS light and a TC (traction control) light. Neither one lights up when I turn on the key. I know I don't have either one because I don't have the RPO codes for them. My question is why is TPMS in my cluster because I dont think it was even available in 2003. I have had the cluster out and I dont think it has been replaced. Does anybody know if TPMS or TC was an option on a 2003 Tahoe?
Thanks
