The adjustable mirrors control unit H030 incorporates the joystick and the control switch for the exterior rear view mirrors.The control unit H030 receives an ignition-controlled power supply (INT), at pin 7, from the line protected by fuse F49 of the junction unit under the dashboard B002 (pin 19 of connector C); pin 5 of H030 is earthed.The control unit H030 operates the adjustment motors inside the driver''s side P060 and passenger side P061 mirrors through combining the above signals: Specifically:- from pin 6 it provides the joint signal for the motors for both mirrors (pin 5 of P060 and P061);- from pins 1 and 2 it controls the movement on the vertical axis of P060 and P061 respectively (pin 4);- from pins 3 and 4 it controls the movement on the horizontal axis of P060 and P061 respectively (pin 3).Pin 8 of H030 receives the power supply for the internal lighting of the mirror adjustment control. See E2535 CONTROL LIGHTSThe electrochromic interior mirror P065 also receives an ignition-controlled supply (INT), at pin 1, from the line protected by fuse F49 of B002 (pin 24 of connector C). Pin 2 of P065 is earthed.The reverse gear engaged signal from switch I020 reaches pin 3 of P065 via the line from pin 8 of connector C of B002 or, on versions with a robotized gearbox, from control unit M054.
