Diagnosis And Testing - UCONNECT Access

WARNING: This page is about a different car, the 2014 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:

To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

The hard wired circuits between components related to the Radio Receiver Module (RRM) (also known as the radio or the head unit) and the Uconnect™ Access system 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 RRM or the electronic controls and communication between modules and other devices that provide some features of the Uconnect™ Access system. The most reliable, efficient and accurate means to diagnose the RRM or the electronic controls and communication related to Uconnect™ Access system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

NOTE:

Validation and diagnosis of many of the conditions listed below will require access to both the paired Bluetooth™ device and the PIN required for that device. 

UCONNECT ACCESS DIAGNOSIS
CONDITION POSSIBLE CAUSES CORRECTION
POOR VOICE RECOGNITION 1. User is not waiting for the beep  tone acknowledgment before issuing Voice Commands. 1. Be certain the user knows to wait for the acknowledgment beep  tone prior to issuing Voice Commands.
2. User is not issuing Voice Commands in a smooth and consistent speaking voice. 2. Be certain the user is issuing Voice Commands in a normal, smooth and consistent speaking voice. The Advanced Speech Recognition (ASR) engine is designed to recognize normal speech patterns and at a normal tone. Some users tend to speak to a computer loud and slow, which results in reduced performance.
3. User is not using proper Voice Command syntax. 3. User must speak using proper Voice Command syntax.
4. High noise levels within the passenger compartment. 4. ASR engine performance is increased when noise conditions in the passenger compartment are lowered. Ideal conditions include having the windows closed and the blower fan set to Low or Off.
5. Passengers are talking while the user is attempting to issue a Voice Command. 5. Although designed to focus on sounds from the driver's seated position, the directional microphones will pick up sounds from any seating position in the vehicle. ASR engine performance is increased in low noise environments.
6. Foreign objects interfering with microphone input. 6. Verify that there are no foreign objects hanging from the inside rear view mirror that could be interfering with microphone reception.
7. The inside rear view mirror is not properly attached to the mount. 7. The inside rear view mirror must be firmly mounted to the mounting location. Be certain the mirror is properly installed.
8. The incorrect Uconnect switch button is being depressed. 8. Phone features are accessed using the Uconnect Phone  button on the steering wheel or the Phone  soft key in the RRM (also known as the radio or head unit) display. Other Uconnect Voice Command features are accessed using the Uconnect VR  button or soft key.
9. Microphone failure. 9. Use a diagnostic scan tool and the appropriate diagnostic procedures for further diagnosis of the microphone.
