CCDIC Segment Check

The segment check illuminates the Instrument Panel Cluster (IPC) and CCDIC to ensure that all segments of the vacuum flourescent displays are working. The turn signal indicators do not light during this check. If all segments are not illuminated, diagnosis should NOT be attempted, as a misdiagnosis may occur (Code E034 appears as E031, etc.). For testing with Codes procedures, refer to the DFI ECM TESTS/CODES or DFI BCM TESTS/CODES article in this section. If any portions or segments of the CCDIC display are inoperative, it must be replaced before continuing with diagnosis.
