BMW 7 Series: Drive, Power Window

NOTES ON INITIALIZING ELECTRIC SEAT ACTUATOR DRIVES

NOTE: Initialization is carried out at the adjusting switch of the relevant seat.

In this process, the end positions of the relevant electric seat actuator drive are recorded and stored.

An initialization must be performed:

• After replacing a drive unit for seat adjustment.
• After replacing/programming control unit for seat adjustment.

Operating sequence for initialization:

Move corresponding seat actuator drive(s) into both end positions.

NOTES ON INITIALIZING POWER WINDOW REGULATOR

NOTE: initialization is performed on the power window switch of the relevant door.

Initialization comprises:

• Normalization
• Learning characteristic curve

With normalization, the mechanical end stops of the power window regulator are recorded and stored.

The characteristic curve is learnt immediately after normalization.

When the characteristic curve is learnt, the mechanical closing forces of the power window are recorded and stored for correct operation of the anti-trapping mechanism.

Initialization, i.e. normalization and learning of characteristic curve, is performed in a continuous operation.

NOTE: An initialization must be performed:

• In the event of malfunctions, e.g. no one-touch function, no opening or no comfort function possible.
• After the power window drive or door module has been replaced.
• After work is carried out on the power window mechanism.

WARNING: There is no anti-trapping protection during initialization.

Necessary preliminary tasks

• Vehicle stationary
• Sufficient battery voltage available/connect charger if necessary
• Terminal "15" switched on
• All doors closed

Operating procedure for initialization (manual):

Erasure of initialization

• Move side window into lower end position.
• Press and hold switch in "Open one-touch operation" position (second switch position) for between 15 and 25 seconds.

NOTE: Deletion of initialization was successful if one-touch control function and anti-trapping protection have been rendered inoperative.

Performing initialization

• Move side window to upper end position
• Pull and hold switch in "Close one-touch operation" (2nd switch position) during the entire process.

NOTE: Re-initialization was successful if one-touch control function and anti-trapping protection function flawlessly.

Alternatively, initialization of the power window regulation can also be carried out via the Service function in ISTA.

Selection via:

• Body
  • Locking and security functions
    • Power windows
      • Initialize power windows

REMOVING AND INSTALLING OR REPLACING FLAT MOTOR FOR FRONT LEFT OR RIGHT POWER WINDOW UNIT

After installation

An initialization must be carried out in order to activate anti-trapping protection.

Read and comply with NOTES on initializing power windows.

REMOVING AND INSTALLING/REPLACING FLAT MOTOR FOR REAR LEFT OR RIGHT POWER WINDOW UNIT

Necessary preliminary tasks

• Remove REAR POWER WINDOW UNIT

Release screws (1) and detach flat motor (2) from power window unit.

Installation: Retaining pins (3) must not be released!
