3315552 - E2022 REVERSING LIGHTS - Functional description (Automatic transmission)

Functional description

The reversing lights switch I20 is supplied by the ignition-operated line (INT/A) of the relay R1 protected by fuse F13 : both are contained in the junction unit B1 . When reverse gear is engaged, the switch closes and sends the supply to the reversing lights in the central rear lights clusters: left F35 and right F36, through the junction unit B1 (pin 7 connector I and pins 6 and 7 connector G). When reverse gear is engaged, a signal is also sent to the interior electrochromic rearview mirror P65 . (  See E3032  DOOR MIRROR ADJUSTMENT ).

Functional description

Its operation is the same as on a manual gearbox, but the reverse gear engaged signal arrives from one of the sensors of the electronic auto transmission sensor assembly (junction D79 ).
