Chart B3 - CCDIC Problem

Fig 1: Chart B3, CCDIC Problem Schematic

You are at this chart because odometer problem has been isolated to CCDIC components or related data link circuitry.

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

This step restores circuit No. 800E into data link circuit. If odometer reads zero, the circuit is shorted to ground or voltage.
This step restores circuit No. 800C into data link circuit. If odometer continues to read correct mileage, the CCDIC must be replaced. If zeros return to the IPC, circuit No. 800C is at fault.
