Diagnosis And Testing - UCONNECT Access

WARNING: This page is about a different car, the 2017 Jeep Cherokee. 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, airbags, airbag curtains, knee blocker, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect the Intelligent Battery Sensor (IBS)/negative battery cable assembly from the negative battery post, 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 hardwired circuits between components related to the Radio Receiver Module (RRM) 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, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, and connector repair procedures. Refer to WIRE SPLICING or REMOVAL or INSTALLATION .

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.

A Light Emitting Diode (LED) indicator between the inside rear view mirror push buttons provides an indication of the status of the Uconnect® Access embedded cellular device. Any fault indication is accompanied by a pop up screen in the RRM electronic touchscreen display. The following indications are provided whenever the status of the ignition switch is ON or Accessory:

Solid Green - No active call.
Flashing Green - A Uconnect® Access Care or 9-1-1 call is active.
Solid Red - A CAN, embedded cellular device, cellular antenna or wiring fault has been detected.
Off - No power supply to the rear view mirror.

In addition to the LED indicator on the mirror, one of the following error messages may appear in the RRM touchscreen display. These error messages will coincide with a solid red mirror LED indication.

Critical VIN Error - This message typically indicates the radio data was not provisioned with the back end database, or that critical data within the RRM is missing. Diagnosis of this type of failure will require the assistance of the network provider.
1. Enter the Dealer Mode menu by selecting the temperature up, temperature down and front defrost buttons simultaneously until the menu appears (about 5 to 8 seconds).
  1. Navigate through the System Information menu to the Radio Part Information menu.
  2. Write down the Serial Number listed on the Radio Part Information menu. The serial number begins with the characters, T00BE .
2. Navigate back to the Dealer Mode menu.
  1. Navigate through the ##Menu Basic menu to the ##RTN# menu.
  2. Write down the MDN number listed on the ##RTN# menu.
  3. Write down the MEID number listed on the ##RTN# menu.
3. Place a call to Uconnect® Care. Provide your dealer code, name, call back number and the Vehicle Identification Number (VIN). Request a ticket be opened with the network engineers to assist with Uconnect® Access diagnostics. A ticket will be opened with the network engineers and a call back will occur within 15 minutes for further assistance and diagnostics.
Vehicle Phone Requires Service - This message can indicate a fault with the antenna, the inside rear view mirror, communication with the Occupant Restraint Controller (ORC) module or any of the hard wired circuits between these components. Check for an active or stored Diagnostic Trouble Code (DTC) for any of the listed components. Follow all of the steps found in the diagnostic information for the retrieved DTC and fully check the hard wired circuitry associated with the DTC. If no DTC can be retrieved, an internal failure within the RRM may exist.

The Wi-Fi hot spot feature can only be diagnosed if the customer has subscribed for this additional feature. The same diagnostic steps associated with Uconnect® Access will be used for Wi-Fi hot spot as they share the same network. In addition, each of the wireless devices of the customer must be properly paired for them to work.

NOTE:

The MIT019 Multi-Media Interface Tester special tool may also be used for testing where no Diagnostic Trouble Code (DTC) has been recorded, such as with Bluetooth® reception and phone pairing issues. Refer to MIT019 MULTI-MEDIA TESTER .

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 acknowledgement before issuing Voice Commands.	1. Be certain the user knows to wait for the acknowledgement 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 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.
