I know by design VSC and Trac Off light up when Check engine light comes on. And I know I have the Bank 2 Cat code. Since the car has been driving with these lights on over the past year with no issues, I'm just waiting for a decent coupon so I can finally purchase a factory OEM Cat to replace it, but in the meantime, does anyone know if there's an alternative way to manually turn off or keep the VSC and Trac activated/standby/working?
