Lost Communication With Door Window Motor D
The ECU has lost communication with door window motor D, a smart window motor with its own bus interface. One-touch and anti-pinch operation of that window stops, and it may work only manually, if at all. Causes: loss of power or ground at the motor, a broken bus or supply wire in the door harness, a damaged door connector, or a failed motor module.
