Test E: The Instrument Cluster Does Not Respond to the Diagnostic Tool
PINPOINT TEST E: THE INSTRUMENT CLUSTER DOES NOT RESPOND TO THE DIAGNOSTIC TOOLE1-E2:
E2-E3:
E4:
Normal Operation
The instrument cluster communicates with the diagnostic tool through both the high speed controller area network (CAN), circuits 1847 (WH/OG) and 1848 (PK/OG), and the medium speed CAN, circuits 1827 (WH/LG) and 1828 (PK/LG). Check both sets of CAN circuits 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 CAN circuits, damage to the DLC C251, damage to the instrument cluster C220, or a problem in an in-line connector.
Possible Causes
- high speed CAN circuit 1847 (WH/OG) open
- high speed CAN circuit 1848 (PK/OG) open
- medium speed CAN circuit 1827 (WH/LG) open
- medium speed CAN circuit 1828 (PK/LG) open
- instrument cluster
- instrument cluster C220
