From : mopar man

Q: ok this worked for me 2001 dodge ram short cab long box 1. ignition switch off 2. press and hold the trip reset knob 3. turn the ignition switch to on but do not start. 4. hold the reset knob for approx 10 seconds or until the word chec appears in the display then release. when i saw chec in the odo display i let go of the trip reset knob and the following numbers appeared one after another 900 920 921 940 950 999 i take it that 999 is like an end-of-code indicator. so im pretty much getting this entire laundry list 900 the ccd data bus is not operational. 1. check the ccd data bus connection at the cluster. 2. check the cluster fuses. 3. check the ccd data bus. 4. check the ccd data bus voltage. 5. check the ccd data bus terminations. 920 the cluster is not receiving a vehicle message from the pcm. 1. check the pcm software level and re-flash if required. 2. use a drb scan tool to verify that the vehicle speed message is being sent by the pcm. 921 the cluster is not receiving a distance pulse message from the pcm. 1. check the pcm software level and re-flash if required. 2. use a drb scan tool to verify that the distance pulse message is being sent by the pcm. 940 the cluster is not receiving an airbag message from the acm 1. check the ccd data bus connections at the acm. 2. check the acm fuse. 950 the cluster is not receiving an abs lamp-on message from the cab. 1. check the ccd data bus connections at the cab 2. check the cab fuse. the truck has been parked for a few days outside and has experienced several bouts of torrential rain. i havent been able to start it since. it was running fine prior to being parked. havent had any problems with it like this since the day i bought it new march 2001. its got no leaks that im aware of. when i turn on the ignition all the guages move. battery moves to 8 volts temp moves to 55 oil pressure moves to 0 and even the fuel guage moves a little but not to the zero or e mark. i guess ill have to poke around under/behind the dash or maybe the engine compartment. if anyones got any tips id love to hear them. .
