PCM to BFC A/C Clutch Data

Table #5 PCM To BFC A/C Clutch Data:

In this mode of operation, the scan tool can command the Body Function Controller (BFC) to read its various data inputs from the Powertrain Control Module (PCM). This mode can be used to determine whether the BFC is receiving data correctly from the PCM and if the PCM is allowing the A/C Compressor to function. The inputs that can be read are listed in TABLE #5 shown in the above figure.
