My speedo quit working last week. Odometer and cruise control. also the ABS, CEL, and Brake light (on instrument cluster) came on.

I have a 2007 2500, 5.9 stock. Automatic Transmission 4wd.

I have replaced rear differential speed sensor, Transmission speed sensor and have checked all fuses for corosion and failure.

also replaced 1 battery that probably didnt need replaced.

Problem continues and the error codes are P0500, U0121, and P2059

I have searched all the sites and have tried about everything I can think of besides replacing a computer. dont really want to go there.

I am stumped on this one. any help at all will be a big plus!!!

He hasn't been here in 10 years. I would suggest that you start your own thread, tell us what you are driving, and what problems you are having, and any codes that are showing.
