2002 Dakota . No bus appears on odometer vehicle shuts down and does not start until no disappears is it the PCM?

The problem you're describing with your 2002 Dakota could be caused by a few different factors, but the most likely culprit is a faulty instrument cluster. The instrument cluster is responsible for displaying various vehicle information, including the odometer reading. If the instrument cluster is not receiving the proper signals from the vehicle's sensors, it can cause the odometer to display incorrect information or even go blank. In addition, a faulty instrument cluster can cause other electrical problems in the vehicle, such as the vehicle shutting down and not starting.

To diagnose the problem, you'll need to have a qualified technician scan the vehicle's computer for trouble codes. The trouble codes will indicate which component of the vehicle is malfunctioning. If the trouble codes indicate that the instrument cluster is faulty, you'll need to have it replaced.

Here are some additional tips that may be helpful:

* Check the vehicle's battery. A weak or dead battery can cause the instrument cluster to malfunction.

* Check the vehicle's fuses. A blown fuse can also cause the instrument cluster to malfunction.

* Try disconnecting and reconnecting the battery. This can sometimes reset the instrument cluster and fix the problem.

If you're not comfortable performing any of these tasks yourself, you should have a qualified technician diagnose and repair the problem.
