Section 1 (Instrument Panel - Electronic): Testing: Notes
WARNING: This page is about a different car, the 1987 Chrysler Conquest. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When a problem in the LCD occurs, turn the ignition switch to the "ON" position and confirm all segments illuminate. If the meter is functional, inspect sensors, wire harness and connectors for damage, looseness or wear. If all systems are functional and the problem persists, the microcomputer is probably defective.
