DESCRIPTION
There are four Radio Receiver Modules (RRM) (1) available in this vehicle, Uconnect® 3 (without NAV) with 5 inch display, Uconnect® 4 (without NAV) with 7 inch display and Uconnect® 4 (without NAV) with 8.4 inch display and Uconnect® 4C NAV with 8.4 inch display. In certain export markets, there is a Uconnect® 4 NAV with 8.4 inch display RRM available. Each RRM has a distinct chassis design and is identified by a sales code.
Hardwired circuitry connects the RRM to the electrical system of the vehicle. These hardwired circuits are integral to several wire harnesses, which routes throughout the vehicle and retained by many different methods. These circuits may be connected to each other and to the vehicle electrical system through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. 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 STANDARD PROCEDURE . and. Refer to REMOVAL . Refer to INSTALLATION .
The RRM cannot be adjusted or repaired. If the RRM is damaged or ineffective, it must be replaced.
OPERATION
The Security Gateway Module (SGW) is the Controller Area Network (CAN) gateway between the radio, telematics modules, Data Link Connector (DLC) and the other vehicle CAN modules. An SGW failure could prevent the radio from powering up, telematics module from communicating or a scan tool from communicating with the vehicle. For additional information on the SGW.
