Electronic Vehicle Information Center (EVIC) Switch Pod
| Refer to COMPONENT INDEX . |
The three lower switches in the EVIC switch pod are normally open, resistor multiplexed momentary switches that are hardwired to the BCM through the steering wheel wire harness and the clockspring on the steering column. The BCM reads the remote radio switch inputs then sends the appropriate electronic messages to the radio over the CAN-IHS data bus to invoke the requested command.
The hardwired circuits between the remote radio switches and the BCM 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 CIRCUIT TESTING PROCEDURES and CONNECTOR TERMINAL REMOVAL and CONNECTOR TERMINAL INSTALLATION .
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the Uconnect® switches or the electronic communication between modules that provide the features of the remote radio switches. The most reliable, efficient and accurate means to diagnose the remote radio switches or the electronic communication related to remote radio switch operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
