The 2019 Ram ProMaster's Electronic Vehicle Information Center (EVIC) screen can go blank, losing trip computer, warning messages, and important vehicle information. This affects commercial operation by removing key data from the driver.
EVIC System
The EVIC is integrated into the instrument cluster, displaying fuel economy, maintenance reminders, warning messages, and other vehicle data. It communicates with various vehicle systems through the CAN bus network.
Causes of Blank EVIC
Display Failure
The LCD display can fail internally, causing partial or complete blackout while gauges may still function.
Cluster Electronics
The cluster's internal electronics process and display EVIC information. Board-level failures can disable the EVIC while other cluster functions work.
Communication Issues
Lost communication with vehicle modules (U-codes) prevents EVIC from receiving data to display.
Power and Ground Problems
Inconsistent power supply or poor grounds cause display dropouts or complete failure.
Partial vs. Complete Failure
If gauges work but EVIC doesn't, the display or its driver circuit likely failed. If everything's dead, power supply is the likely cause.
