Good morning. I can help you out with this. F32 is a BCM code. It indicates a problem with the communication data line between ECM and BCM. E15 is open coolant temp sensor circuit.E19 is shorted fuel pump control circuit.E40 indicates a problem with the power steering pressure switch circuit.E51 isn't a valid trouble code, and E52 simply means that the memory has been reset.... they all have E52 in them, so disregard that one. Now, what symptom are you having with your car? Does it start/run/drive well?
