Rear window blind does not operate
Transaction No.: 2063296/1
Customer statement / workshop findings
Rear blind does not operate
Technical background
The most common failure modes are as follows:
•
Rear blind does not operate following a CAN bus sleep, If the switch operation is a prolonged hold, instead of a ‘Press and release’
operation
•
Rear blind does not operate following loss of CM basic settings
•
Rear blind will also not operate if the ‘Child Lock’ is on
•
Rear blind 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).
Production change
Currently under investigation
Measure
The following actions can be taken to resolve the problem where possible:
•
Operation of the button a second time will return functionality, if the stopped due to a CAN bus sleep
•
A hard reset is required if the failure is caused by CM loss of setting. Recovery of windows basic settings can be done by pulling up on the
window switch and holding for minimum 12 seconds -Then press down and when down and hold the switch for 12 seconds
•
If the ‘Child Lock’ is switched on, there will be no possible blind, window or internal door handle operation until ‘Child Lock’ is switched off
•
If the blind does not operate as a result of repeated operations in a very short space of time, the blind and window CM needs to be hard
reset to regain normal operation
•
As instructed in the owner’s handbook, the blind will not operate if window is in the lowered position
•
The blind will also not operate in extreme cold temperature for example:
-10 degrees Celsius or 14 degress, Fahrenheit.
•
Retailers to advise customers that blind operation only requires a simple push/pull and release of the switch to lower or raise blind at first
vehicle start up.
Please raise a DISS query to record any customer complaints which relate to rear blind operation
