L1-L2:






L3:






Normal Operation
The climate controlled seat module communicates with the diagnostic tool through the medium speed controller area network (CAN), circuits 2180 (WH/BK) and 2181 (BK/YE). Check circuits 2180 (WH/BK) and 2181 (BK/YE) between the climate controlled seat module C3265b 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 climate controlled seat module C3265b, or a problem in an in-line connector.

Possible Causes
- medium speed CAN circuit 2180 (WH/BK) open
- medium speed CAN circuit 2181 (BK/YE) open
- climate controlled seat module
- climate controlled seat module C3265b
