PINPOINT TEST E: NO CONTROLLER AREA NETWORK (CAN) COMMUNICATION


E1-E3:






E4-E6:






Normal Operation
The CAN has an unshielded twisted pair cable, data plus circuit 1827 (WH/LG) and data minus circuit 1828 (PK/LG). Check the CAN circuits between instrument cluster 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 C220b, or a problem in an in-line connector.

Possible Causes
- CAN data plus circuit 1827 (WH/LG) open, short to ground, or short to voltage
- CAN data minus circuit 1828 (PK/LG) open, short to ground, or short to voltage
- DLC C251
- instrument cluster C220b
- instrument cluster
