The electric window system is managed by control unit M135 (ABI). The control unit is ignition-operated - pin 8 connector B - and protected by fuse F35, housed in underfacia junction unit B002.An ignition-operated power supply is distributed from short-circuit juntion D097E, to control unit M135, and also switches H044 - pin 2 connector A and B - and H050 - pin 2 -.Control unit M135 is connected as follows:

  • pin 8 : raise control for left window motor N060;
  • pin 9 : lower control for left window motor N060;
  • pin 11 : lower control for left window motor from switch unit H044 - pin 3 conector A -;
  • pin 10 : raise control for left window motor from switch unit H044 - pin 4 conector A -;
  • pin 5 : lower control for right window motor from switch unit H044 - pin 3 conector B -;
  • pin 18 : raise control for right window motor from switch unit H044 - pin 4 conector B -;
  • pin 2 : lower control for right window motor from switch H050 - pin 3 -;
  • pin 6 : raise control for right window motor from switch H050 - pin 4 -;
  • pin 1 : raise control for right window motor N061;
  • pin 3 : lower control for right window motor N061;
Controls H044 and H050 come with internal lighting that comes on when the side lights are turned on.The side light activation signal comes from control panel H090 - pin 12 connector C - and is distributed from junction D097E to the appliances. A light activation signal reaches control panel H090 - pin 2 connector A - from a line protected by fuse F24, located in underfacia junction unit B002.Control unit M135 receives power directly from the battery at pins 15 and 16, from a line protected by fuses F47 and F48 located in optional underfacia control unit B101.
