K2-K3
Normal Operation
The dual automatic temperature control (DATC) module or electronic automatic temperature control (EATC) module both 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 DATC module C2356a or the EATC module C228a 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 high speed CAN circuits, damage to the DLC C251, damage to the DATC module C2356a, EATC module C228a, or a problem in an
in-line connector.
