Fusion L4-2.3L VIN Z (2006)
Normal Operation
There are 2 types of audio units used on this vehicle, the base audio unit and the THXII audio unit (if equipped). Both audio units communicate 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 audio unit C290b or THXII audio unit C240c (if
equipped) 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 audio unit C290b or THXII audio unit C240c (if
equipped), or a problem in an in-line connector.
