67 62... Notes on initializing power window unit in front door (coupe)
There is no anti-trapping protection during initialization.
Rear power window unit does not have one-touch control function or anti-trapping protection and therefore does not require initialization.
Initialization is performed on the power window switch of the relevant door.
Requirements for correct initialization:
- Terminal "R" activated
- Convertible top, doors and windows closed
- Sufficient battery voltage; connect charger if necessary
Initialization comprises:
- Erasure of initialization
- Reinitialization
An initialization must be performed:
- In the event of malfunctions, e.g. no one-touch control function, no opening or if available no comfort function is possible
- After the power window drive has been replaced
- After work is carried out on the power window mechanism
- If necessary, after a power supply interruption, e.g. disconnection of the battery or disconnection of the power supply to the door
- After the door window glass has been removed and installed or replaced
- After adjustment work on the door window glass
- After adjustment work on the convertible top
- After replacement of seals
Erasure of initialization:
- Open door window glass fully
- Actuate power window switch in "Open" position (second switch position) and hold down for between 15 and 20 seconds
This erases initialization of the power window, anti-trapping protection and toll function are inactive.
Check whether one-touch control (toll) function is inactive, otherwise repeat procedure.
Reinitialization:
- Close door window completely
- Once the upper end position has been reached, hold power window switch in "Close" position (second switch stage) for approx. 2 seconds longer
This completes initialization.
