gotta fix and program my cs310i

So I bought a truck with a command start (cs310i) installed in it but it had no remote. Went to the local command starter install shop to get a remote and have it programmed but they told me a diode in the brain was burnt out. Has anyone come across this before?

Im going to take it apart tonight and look for any bad diodes and replace if neeeded.

Also If anyone has the programming manual for this model I would appriciate a copy  so I can program a remote and set up the system.

Thanks
