Segment Check

The purpose of illuminating the Instrument Panel Cluster (IPC), Climate Control Panel (CCP) and Driver Information Center (DIC) is to check that all LED segments are working. The turn signal indicators on the IPC will not illuminate during this check.

Further diagnosis should NOT be attempted unless all the CCP and DIC segments appear, as this could lead to misdiagnosis. If any LED portions or segments of the CCP or DIC display are inoperative, the Combo Panel must be replaced. If the entire display is blank, go to the SELF DIAGNOSTIC SYSTEM CHECK  .
