  The right front door control unit supplies the connected control elements with c. 58d.

  Interior CAN 

  The right front door control unit reads in the following signals via the interior CAN

  • Terminal status of terminal 15
  • CL locking unlocking/locking request
  • PRE-SAFE® adjustment request
  • Request to move to memory position (with CODE P64 (Memory package))
  • Convenience feature request
  • Crash signal

  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 front door control unit actuates the following components over direct lines:

  • Right front door lock:
  • Right front door central locking motor (A85/1m1)
  • Right front door additional door lock actuator motor (A85/1m4) (with code (885) Increased theft protection)
