A strange one
When the WTS light went out I started it and the same thing happened the speedo maxed and dropped to 0 and the odometer read E 08 3. While driving the speedometer stayed at 0 and when I hit the select button that would switch to trip meter the odometer read 111111 then when I hit it again it went to 222222 then 333333 and so on. All other gages seemed to work fine. This happened every time I started the truck then while driving I hit the set button that would set the trip meter to 0 a bunch of times and every thing went to normal and it looks like the miles I added while it was acting up were added. What was all that about??????????????

This is for a 2003..not sure if our trucks are the same:
Instrument Cluster Dealer Test Mode
To enter the Instrument Cluster Dealer Test Mode, depress and hold the instrument cluster SELECT/RESET button and then turn the ignition switch to the RUN position. Continue pressing the SELECT/RESET button (five seconds) until tESt is displayed in the odometer. The SELECT/RESET button must be released within three seconds of the odometer displaying tESt to begin the dealer test mode. Depress the SELECT/RESET button to advance through the following steps until dtc is displayed. Depressing the SELECT/RESET button will display any continuous DTCs stored before proceeding to the next step.

Looks like I just stumbled into this. So far it looks like this truck only gets 9 MPG! It has a dump on the back and gets nothing but city driving. Never have too much weight in the back. Maybe 4 to 500 pounds. What do you think of the MPG?
