i have a 2011 s40 t5 that shows anti skid service required.also p0600. will anti skid cause p0600.and how do you correct the problem without taking it to a dealer

 

Take it to an independent that has the capability of diagnosing and fixing it.

 

P0600 is saying the ECU has stopped talking to one of the other controllers. As hoonk noted, its not a direct diagnosis so you need a tech with appropriate tools (ie a VIDA diagnostics tool) and experience to diagnose. Truth is, many indy's will see an issue like this and refer you to the dealer.
