I knew this was coming for a while now! Once in a while when I start the rig it would tell me DEFECTIVE DISPLAY. So I would shut it off and re start it and that was that. But not this time; when I re-started the rig the check engine light came on and it says ENGINE ELECTRONICS I pulled the codes and here they are.

0500 Vehicle speed signal
0600 CAN of ESP
0720 Read ETC fault memory
1605 CAN acceleration info for poor road recognition from ABS speed sensor

Any ideas? Is it a DIY or do I have to apply for credit
