I am new to this and do not know what to start with.
I have a climate control out of a 2004 Lincoln I want to place in a street rod.
The climate control uses the CAN to communicate to the ECM to determine when the engine is warm enough to turn on the heat. it also requests the engine RPM.
It also requests the AC Compressor engage through the CAN to the ECM. The ECM then controls the AC compressor.
If the Climate Control has any errors, it is transmitted through the CAN. I am not sure if they are held in the climate control until called for or broadcaster and collected by the ECM and collected there.
I need remove the ECM as that engine will not be used, create an ECM that will transmit the new engine temperature and RPM and also turn the AC Compressor on and off when commanded by the climate control.
As for the CAN portion, which item(s) will accomplish this?
The engine temperature is an analog input and the RPM input will be a tachometer input. Both would need to be converted to CAN to satisfy the climate control.
The AC request would be converted to a binary output operating a relay.
As for the trouble codes, not sure about those yet.
I understand there are CAN protocols for this. Do any of these handle them?
