Chart B-3

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 IPC is lit with no display, the likely cause is a circuit 801A problem.
3. If the IPC is black (not lit) some characters may be seen faintly, with no backlighting. This branch will check powers and grounds that could cause this symptom.
4. If the CCDIC is black (not lit) some characters may be seen faintly, with no backlighting. This branch will check power and grounds for the CCDIC.
