Fusion FWD L4-2.3L VIN Z (2007)
L2-L4
Normal Operation
The THX(R) amplifier communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits VDB06 (GY/OG)
(MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the THX(R) amplifier. The THX(R) amplifier shares the
MS-CAN network with the instrument cluster, the electronic automatic temperature control (EATC) module (if equipped), the dual automatic
temperature control (DATC) module (if equipped), the audio unit, the satellite radio receiver (if equipped), the driver seat module (DSM) (if
equipped), the driver door module (DDM) (if equipped) and the climate controlled seat module (if equipped). Voltage for the THX(R) amplifier is
provided by circuits SBB20 (GN/RD) and SBB21 (GY/RD). Both circuits GD148 (BK/YE) provide ground.
