Dodge and chysler caravan gauges not working or bouncing

well there could be a few things but i would first ask is the speedometer the only thing not working? if so i would have the (vss)vehicle speed sensor tested. but if there are other issue's with in the insturment cluster then try this... this is a tip and trick i wrote here on fixya. i see this all the time in my shop...

this is a communication ccd error code from pcm to transmission.

i have found a fix that will be easy and cheap if you have soldering skills and a soldering iron. this will also fix your gauges from not responding or not working.

Remove your instrument cluster and check the solder joints on the back of the cluster main board. You may have to flex the board to see the cracks in the solder. i have found the main connector soldering joints to be cracked. more common is the bottom row all the way to the right pin. you will need to remove the board off the plastic cluster housing and flip it over.

look for the two rows of pins that are for the red plugs main connector. check them very well and re solder any in question.

It means that it didn't receive a signal from the transmision module.
Have your transmission control module checked.

To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.
