Troubleshooting: 46 yards into the comfort system address, check fault code is: “01173 – Driver-side front seat height adjustment Electric / Comfort system data bus failure.” Diagnostic interface to enter data address code 19, the query to the meaning of the data bus fault single pattern fault code. Connection failure diagnostic VAS5051 comfort system bus waveform observation, found that low line-to-ground short circuit. As the data diagnostic interface to the star system control unit and comfortable way, 4-door electric seat control module and control unit connected in the four door and seat control module electrical plug disconnected, the measured waveform is still very high bus line single run.
