So my questions are, does anybody know about the P2000 code being ignored by diagnostic system and secondly does it seem reasonable to have so many seemingly unrelated codes? [quote]
2 weeks ago, I had a CEL for my EGR code P245A...Tech did a TSB 18-033-07 and flasher the controller. 1 week later, got a CEL again...the P2000 code. Tech. told me that there are software communications problems the the ECM and that is the reason for P2000 codes. They replaced my ECM with the latest version ( only one in 6 states I'm told) So far no problems... We'll see
