Our team is trying to run a compressor with one solenoid, and both are wired into the PCM. However, we can't get it to run. Our compressor is wired as it should be, but our compressor isn't doing anything.
The Status light on the PCM is strobing red, which according to
http://crosstheroadelectronics.com/PCM%20User's%20Guide.pdf
means that the problem is that there is no CAN communication.
We are not planning to implement CAN at all this year, but I have been seeing some things about updating the PCM firmware. Do we need to update the PCM firmware to be able to run our compressor, even though we have no plans of implementing CAN?
