I followed the procedure outlined by autel. I had a codes 5DF1: pump motor connector faulty, 5DF0: pump motor. The codes would come and go intermittently but would stay a day or so active. Wiring was good and I updated the old module, continued with same codes after running other tests found the module was bad. Removed and installed new module and followed autel procedure for replacement. I now have the same codes plus 5DD0 adjustment DSC unit (valves), 5DD2 DSC unit valves. I have done a complete system software updated on the vehicle also.
