How do I test my ECM/PCM? Truck just died. No power to ecm/pcm. No bus5 code is on dashboard. Really enjoy your teaching skills they are top notch!

Do you have a scanner that can talk to all the modules on the vehicle? Check see if you have a 5 volt reference at the tps sensor. Key on engine off. Let us know what you get

No I don’t have a tool to talk to the modules. Just a scan tool. With a no bus5 it’s useless. I don’t have 5volts on the tsp . Though I have checked all fuses and wiring. Can’t find any bad so far. Still looking. Thank you for your help.Tracy
