PCM to BFC A/C Clutch Data

Description:

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 Body Function Controller (BFC) is receiving data correctly from the Powertrain Control Module (PCM) and if the Powertrain Control Module (PCM) is allowing the A/C Compressor to function. The inputs that can be read are listed in TABLE #5
