Test D: The Instrument Cluster Does Not Respond To The Diagnostic Tool - Medium Speed Controller Area Network (CAN)

PINPOINT TEST D: THE INSTRUMENT CLUSTER DOES NOT RESPOND TO THE DIAGNOSTIC TOOL - MEDIUM SPEED CONTROLLER AREA NETWORK (CAN)

D1:

D2-D3:

Normal Operation
The instrument cluster communicates with the diagnostic tool through the medium speed CAN, circuits 1847 (WH/OG) and 1848 (PK/OG). Check circuits 1847 (WH/OG) and 1848 (PK/OG) between the instrument cluster C220 and the data link connector (DLC) C251.The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in one of the medium speed CAN circuits, damage to the DLC C251, damage to the instrument cluster connector, or damage to an in-line connector.

Possible Causes
- medium speed CAN circuit 1847 (WH/OG) open
- medium speed CAN circuit 1848 (PK/OG) open
- instrument cluster C220
- instrument cluster
