HelloWhen the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

your speedo cable is broben

I doubt the problems are connected.The check engine light could be anything including the loose gas cap.But if that was the only problem it would not keep the truck from moving.If it starts and runs, but won't go into gear, something has happened to the transmission or axle. You may have to get it towed to a shop to find out what the trouble codes are in the computer.

negative you will have to remove the radio and reset by unpluging and pluging back the power plug
