Pinpoint Test 5

PINPOINT TEST 5: NO CONTROLLER AREA NETWORK (CAN) COMMUNICATION

Normal Operation
The CAN has an unshielded twisted pair cable, data plus circuit (W/LG) and data minus circuit (P/LG). Check the CAN circuits between instrument cluster and the data link connector (DLC) D-01. 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 D-01, damage to the instrument cluster 0922-101, or a problem in an in-line connector.

Possible Causes
- CAN data plus circuit (W/LG) open, short to ground, or short to voltage
- CAN data minus circuit (P/LG) open, short to ground, or short to voltage
- DLC D-01
- instrument cluster 0922-101
- instrument cluster

CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.
