DTC Chart: Air Conditioning Control Module (ACCM)

NOTE: The ACCM is integral to the A/C electric compressor and cannot be serviced separately.

NOTE: Before testing of the A/C electric compressor ACCM with a diagnostic scan tool can be performed on HEV, the vehicle must be in Ready to Drive mode. Switch the ignition on with transmission selector lever in position P. Look for the green ready indicator light to appear in the lower right portion of the instrument cluster and a ready to drive message to appear in the middle of the left cluster screen.

Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices.
