Milan L4-2.3L VIN Z (2006)
J2-J3
Normal Operation
The climate controlled seat module communicates with the diagnostic tool through the medium speed controller area network (CAN), circuits VDB06
(GY/OG) and VDB07 (VT/OG).
Check the medium speed CAN circuits VDB06 (GY/OG) and VDB07 (VT/OG) between the climate controlled seat module C3305c 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 C3305c, or a problem in an in-line connector.
Possible Causes
-
medium speed CAN data plus circuit VDB06 (GY/OG) open
-
medium speed CAN data minus circuit VDB07 (VT/OG) open
-
climate controlled seat module C3305c
-
