UCONNECT + SIRIUSXM Guardian: Operation

WARNING: This page is about a different car, the 2022 Chrysler Voyager and 2022 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.

Uconnect® + SiriusXM® Guardian capability relies on cellular (telematics) technology and subscribed services that are controlled through Digital Rights Management (DRM). The management or DRM along with specific services occur wirelessly through the cloud. Digital rights and a subscription determine the specific services a customer is eligible to receive. Data feeds between assembly plants and its radio suppliers are provided to the cellular provider to enable initial capability or provisioning. This initial data must exist in the database of the cellular provider or functionality will be unavailable. Base features are supported through software that exists within the applicable Radio Receiver Module (RRM) platform and cellular connectivity is provided through the embedded cellular module.

Signal strength and data capability is shown adjacent to the Apps orb soft key found at the lower center of the radio touchscreen. Depending on location and coverage, data capability can change. Signal strength is a major factor for any wireless connectivity. Fourth Generation (4G) data is the highest connectivity available at this time, however, the system will also connect at 3G if 4G is not available. Remote Service features (Start, Lock, Unlock, and others) rely on data capability. If the vehicle is located in an area of no or low coverage, the Remote Services features may not function. Signal strength and data capability can suffer from the same situations any cellular device might experience. Parking structures, blocks, drops and dead zones can affect performance at any time.

The two switch buttons on the inside rear view mirror identified with ASSIST and SOS provide a resistor multiplexed input to the Local Interface Network (LIN) slave node integral to the inside rear view mirror. The LIN slave node sends an electronic switch press message to the LIN master node integral to the Body Control Module (BCM). The BCM relays the message over the CAN-IHS data bus, where it is retrieved by the RRM.

The hardwired circuits between components related to the RRM and the Uconnect® + SiriusXM® Guardian 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® + SiriusXM® Guardian system. The most reliable, efficient and accurate means to diagnose the RRM or the electronic controls and communication related to Uconnect® + SiriusXM® Guardian system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
