The Reductant Warning Service Bay Test is what we usually run once we’ve fixed the vehicle, DTC’s cleared and all that remains is a warning message on the DIC. Usually when a service emission system warning message came on. But hopefully in your case it has fixed the truck and there won’t be anymore problems. The system can be frustrating at times. And for reference the system has 11 levels of “Tampering” and each level has its effect on vehicle operation. Like reducing vehicle speed to 4mph, cause that’s needed.....lol
