- with CODE (500) Folding left/right outside mirrors
- up to model year 08

Component Identification:

Manually folding-in/out, function

Function requirements
^ C. 15R On
^ No mirror lens adjustment active
^ Speed signal < 47 km/h for folding in mirror housing

Function
When the outside mirror fold-in/out switch is switched momentarily, the mirror housings can be moved to the garage position (folded in) or driving position (folded out). The corresponding adjustment request is read in by the left door control unit via door LIN.

The left door control unit has the master function during adjustment and relays the signal to the right front door control unit via the passenger compartment CAN-B bus.
The left door control unit actuates the mirror fold-in motor in the left outside mirror and the right door control unit actuates the mirror fold-in motor in the right outside mirror.
If the function requirement c. 15R ON is not present after starting to fold in or out the adjustment is continued until the end position is reached.

Automatically folding in/out, function

Function requirements
^ Circuit 15C OFF
^ Function in COMMAND controller unit activated
^ Mirror housing last actuated in folding out direction (when folding in)
^ Mirror housing previously folded in automatically (when folding out)

Function
When the vehicle is locked with the central locking (CL) from outside with the transmitter key (A8/1), both mirror housings are folded in automatically (garage position). The next time the vehicle is unlocked with the CL and the driver or passenger door are opened, the mirror housings are returned to the previous position

If the mirror housings are still folded in with circuit 15R ON by a previous automatic folding-in procedure, the mirror housings are folded out immediately.
If the mirror housings were manually adjusted to the garage position, the mirror housings are not adjusted via the automatic adjustment
The master for this function is the left front door control unit, responsible for adjusting the left mirror housing as well as for transmission of the corresponding signals to the right front door control unit via the interior CAN to actuate the right outside mirror housing.

Abort conditions
Movement to the position is interrupted if:
^ Active outside mirror lens adjustment
^ Manual fold-in/out
After interruption, function is continued.
