POWER SLIDE DOOR SYSTEM When Engine is Running or Stopped and Door Control Switch is Pressed, Door does not Open or Close (LH Door)

DESCRIPTION

The slide door motor unit LH (slide door ECU LH) receives the slide door open/close switch signals from the main body ECU (multiplex network body ECU) and performs power slide door open and close operations.
