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

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

C1-C2:

C3:

Normal Operation
The instrument cluster communicates with the diagnostic tool through the high speed CAN, circuits 1827 (WH/LG) and 1828 (PK/LG). Check circuits 1827 (WH/LG) and 1828 (PK/LG) 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 high speed CAN circuits, damage to the DLC C251, damage to the instrument cluster C220, or damage to an in-line connector.

Possible Causes
- high speed CAN circuit 1827 (WH/LG) open
- high speed CAN circuit 1828 (PK/LG) open
- instrument cluster C220
- instrument cluster
