B1350

CIRCUIT DESCRIPTION
DTC B1350 is designed to disengage the A/C compressor clutch in the event that coolant temperature exceeds 126°C (258°F). The Air Conditioning Programmer (ACM) receives coolant temperature information from the PCM via class 2 serial data bus. While DTC B1350 is current the Instrument Panel Cluster (IPC) will display "ENGINE HOT - A/C COMPRESSOR OFF" on the Driver Information Center (DIC) to warn the operator. Refer to "Engine Controls" (PCM) for more information. This code will also set whenever code B1016 is set.

TROUBLESHOOTING HINTS
Make sure PCM is operating properly. Refer to PCM diagnostic System Check. If the PCM is operating normally replace the ACM.
