Diagnosis And Testing
WARNING: This page is about a different car, the 2020 Jeep Renegade. However, it is still accessible from the selected car via links, so may be relevant.
The Electronic Vehicle Information Center (EVIC) data is obtained from several components on the Controller Area Network (CAN) data bus. The EVIC will not function properly if the bus messages from any of these components is not received. If no EVIC data is displayed, check the CAN data bus communications, the Instrument Panel Cluster (IPC) functions and the Body Control Module (BCM).
The use of a scan tool and the proper diagnostic procedures information are recommended for additional testing of the EVIC and the CAN data bus. Refer to the appropriate wiring information for complete circuit schematic or connector pin-out information.
