Chart B-4

You have been sent to this chart due to display problems with the Computer Control Driver Information Center (CCDIC) or Instrument Panel Cluster (IPC). This chart will lead through a check of power and ground circuits to the effected display.

Notes on trouble trees
1. This step assures that the BCM is initialized correctly to observe the symptoms.
2. If the IPC voltmeter does not display system voltage but the Driver Information Center (DIC) does display, the problem is circuit 250, or diagnostic should function.
3. If the DIC is black (not lit) some characters may be seen faintly, with no backlighting. This branch will check power and grounds for the CCDIC.
