Right rear door external operation microswitch (A85/4s4) (with CODE 883 (Power closing))
Hall sensor in right rear door power window motor (M10/6)
Right rear door power closing actuator motor microswitch (M14/24s1) (with CODE 883 (Power closing))
Right rear power window switch (S214)

The rear door control units connect the connected control elements with circuit 58d.

Interior CAN

The rear door control units read in the following signals, among others, via the interior CAN:

The functions that use these signals are described in the individual function descriptions (see appropriate block diagram or function schematic).

Evaluation of input factors

The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

Actuation of components

The following components are actuated by the left rear door control unit via direct lines:

Left rear door lock:
- Left rear door central locking motor (A85/3m1)
- Left rear door additional door lock actuator motor (A85/3m4) (with code (885) Increased theft protection)
Left rear door exit and warning lamp (E17/5) (model 166.0, 292 with CODE 876 (Interior light package), model 166.8)
Left rear door handle illumination (E1713)
