Diagnosis And Testing - Hands Free Module

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.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the HFM or the electronic controls and communication between modules and other devices that provide some features of the Uconnect™ Hands Free Communication system. The most reliable, efficient and accurate means to diagnose the HFM or the electronic controls and communication related to Uconnect™ Hands Free Communication system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
