Bulb warning light stuck on

I have a 2008 suburb which shows on the MfD that the 'right rear fog light not working' I inspected all lights and found them to be working correctly. I carried out the Guided fault finding on ODIS which didn't help at all. I have replaced the bulb, inspected wiring all seems ok but the light remains on the mfd. There is only 1 connector between the voltage control unit and the bulb, this connector is ok. The light still remains on the mfd has anybody come across this before?
