•

Letterbox-style flap is loose or detached

•

Technical Background
NOTICE
The following most common failure modes should be considered before proceeding with the replacement of the rear side
window blind
•

Rear blind/s do not operate following a CAN bus sleep

•

Rear blind/s do not operate if the switch operation is a ‘prolonged’ hold instead of a ‘Press and release’ operation

•

Rear blind/s do not operate following the loss of control module basic settings

•

Rear blind/s will also not operate if the ‘Child Lock’ is on

•

Rear blind/s will cease to operate if there are repeated operations of the blind sufficient to trigger a failsafe mode (usually between 10 to 15
operations in a very short period)

•

As instructed within the owner’s handbook, the rear blind/s will not operate if the rear window is in the lowered position

•

The blind will also not operate in extreme cold temperature for example -10 degrees Celsius or 14 degrees, Fahrenheit.

Once all failure modes above have been considered, investigate the door blind for the following:
•

Misplaced or dislodged letterbox flap return spring, leading to uncontrolled or inconsistent flap movement.

•

Detached letterbox flap from housing due to weakened or broken retaining element.

•

Sheared connecting rivet at the junction of the aluminium and plastic housing, compromising the structural integrity of the assembly.

Perform a visual inspection of the rear window door blind and investigate for possible failure modes listed above, raise a non-technical DISS and
if required replace the rear door blind and return the defective blind via the standard parts return system ensuring the rear blind is suitably
protected. Once received the blind will be returned to the supplier for further investigation.
Follow the steps the in the measure section for further information.
