SUBJECT
Rear Window False Anti-trap Activation
MODEL

INFORMATION
The anti-trap protection feature may be activated when no obstruction is present. This may occur at either one or both of the rear windows.
The root cause of the false anti-trap activation may be difficult to determine. The attached diagnosis flowchart has been developed to assist with
determining the actual root cause of the failure as well as to help prevent unnecessary part replacements.
The root cause is typically either an issue with the window system, or an electrical/software issue. The diagnosis flowchart will help ensure that
repairs are only carried out for the system that is most likely at fault.
