Does U.S. JB4 clear codes?
 

I tried clearing codes today with no luck through the cluster software. Will a U.S. version of the JB4 clear faults through the cluster or JB4 software?

Furthermore, the car set a Tmap short circuit fault today, CEL and car feels and sounds off. Hearing a loud hissing noise @ WOT. Sounds like the wastegate is just dumping. This is on MAP 3.

Yes you can delete fault codes in the USA. But, if there is a problem with the car then the codes for that problem won't clear.

So check your TMAP, maybe its loose, chargepipe blew off, etc?
