First bow hits Tonneau cover when lowering top
a. Programming
Reprogram top according to PSI

Pay special attention to the
Tonneau motor high limit,
b. Tonneau motor drive shaft twisted?
If
the Tonneau motor drive shaft is twisted, the 5th bow may hit the Tonneau
cover hinges. If you think that this situation exisits, you may have to remove
the u-joint at the end of the shaft to inspect it for a twist.
If the shaft is twisted,
you must replace the Tonneau motor assembly and determine the cause of
the twist. A twisted shaft is usually due to misadjusted Tonneau cover
latches. Make sure the latches are carefully adjusted according to Service
Manual
8:5,
pages 127
&
128. Make sure to check the Tonneau latch adjust-
ment with top fully raised, because the 5th bow pushes the Tonneau cover
down when the top is fully raised.
c. Bent Tonneau cover hinges?
The Tonneau cover may not open far enough because the Tonneau hinges
are bent.
Note that this condition is not very common.
If you have determined that the
Tonneau cover hinges are actually bent, you must replace the hinges. See
Service Manual
83
Cabriolet, pages 218-219.
You must also determine the cause of the bent hinges. Tonneau hinges could
bend due to incorrect Tonneau latch adjustment. See the illustration in Step
#4
of this guide.
