Chart C1 - CCDIC Symptom Diagnosis

Fig 1: Chart C1, CCDIC Symptom Diagnosis Schematic

This chart should be used to identify symptoms relating to CCDIC problems. There are 2 major checks that must be made, a visual check of the display, and a keyboard functional check.

NOTE: Test numbers refer to test numbers on diagnostic chart.

If the CCDIC display is totally blank, go to CHART C2. If Climate Control Panel (CCP) is blank, but Driver Information Center (DIC) reads "SYSTEM PROBLEM", go to CHART C3. Any other display problems are due to the CCDIC and it should be replaced.
If the "TEMP/TIME" button is the only inoperative button, go to CHART C4. Cause of problem may be an open in circuit No. 1018. If none of the buttons on the engine panel respond, the CCDIC panel or BCM should be replaced.
If the DIC buttons do not respond, check BCM input B130. This checks to see if the BCM and related wiring are at fault, or the CCDIC panel.
This step checks to see if there is a short to ground in circuit No. 1018, a faulty BCM, or a faulty CCDIC panel.
