What you are saying is logical. I think the instructions assume you would get the codes cleared by the dealership, in which case you would not want the defeat plug installed for that, because it would disrupt their troubleshooting steps and cause them to blame your aftermarket part for the trouble. But if you are clearing the codes yourself, then doing it after installing the defeat plug seems like a sensible approach.So I have the P1E00, P0AA6, and P1FFF codes and SHVCS warning. Battery coolant level is at the bottom of the black label (not top, but pretty far above the seam), so I’m guessing guessing it’s the sensor. I’ve purchased the Canbus SHVCS Defeater plug and the VCX Nano. I’ve read all the instructions and everything seems pretty straight forward. However... the instructions say I need to clear the codes before installing the defeater plug. Wouldn’t they just come right back on if I did it in that order? Wouldn’t it make more sense to first plug in the defeater plug, then clear the codes out?
