Diagnosis And Testing: Navigation
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.
For information on diagnosing the GPS satellite navigation system, use the POOR OR NO GPS RECEPTION test. Refer to DIAGNOSIS AND TESTING .
The hardwired circuits between components related to the radio and the Uconnect® Navigation system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, 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 .
However, conventional diagnostic methods will not prove conclusive in diagnosing the radio or the electronic controls and communication between modules and other devices that provide some features of the Uconnect® Navigation system. The most reliable, efficient, and accurate means to diagnose the radio or the electronic controls and communication related to Uconnect® Navigation system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
