Think I might get one of these scanners to aid in my purchase. Let’s say I take it with me and check this D2 with an ABS light on.. what would be a code that is a definite red flag to stay away from? And better yet, in general what are some of the most pesky codes (with regard to any of the “3 amigos”) to fix (time and money)?

 

None of the amigo codes are typically expensive. There's always a very slight possibility that the SLABS computer itself is the culprit and would need to be replaced. That's extremely uncommon. Most codes are either a wheel speed sensor, or shuttle valve related. Speed sensors and hubs are cheap, can be a pita if you're not familiar with tools. The shuttle valve fix is called Option B, search and there's a good write up on it.

Another good option for a code reader that's cheap, reliable and reads is the Autel A619, or iCarsoft. They'll be cheaper and both read and reset CEL, ABS and SRS codes.
