The hard wired circuits of the Hands Free Module (HFM) (also known as the Bluetooth™ module) may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin out information and location views for the various wire harness connectors, splices and grounds.

The most reliable, efficient and accurate means to diagnose the HFM or the electronic controls and communication related to Uconnect™ Hands Free Phone system operation requires the use of a diagnostic scan tool.
