Yes, I searched the Forum...
Top was working perfect last week. Tried to open and the rear of the Tonneau panel catches on the front of the bed cover. If I remove the bed cover, the top works well.
The problem appears to be the rear of the tonneau cover does not lift up before the cover starts to move towards the rear. The cover then pinches against the front of the bed cover. No codes are indicated on the dash. If I stop the cover after it starts to move and manually lift the rear of the tonneau to clear the front of the bed cover, it will work. So the rear of the tonneau is not lifting enough. Also driver side starts to move before the passenger side.
Mine was made before the change from rubber hose to delrin bushing, but that does not appear to be the problem. I made PTFE bushings and it did not help.
The fluid level was right at the "minimum" mark so I filled to half way between minimum and maximum. I was hoping it was just low fluid. Still won't open without catching on the bed cover.
No signs of leaking fluid.
The two hydraulic rams that lift the Tonneau cover appear to fully extend, just not soon enough. (The two short rams that are vertical at the rear of the compartment.)
Problem seems to occur between step 2 and 3. in this list.
The sequence for opening the top is as follows when holding the retractable roof switch to the OPEN request position:
1. Driver and passenger windows index down
2. Tonneau latch extending to unlatch
3. Tonneau latch extended, opened
4. Tonneau panel extending upward, opening
5. Tonneau panel extended upward
6. Front tonneau extending
7. Front tonneau extended
8. Header latch unlatching
9. Top panel dowel pins activate that top panel is not over center and unlatched
10. Top panel retracting, to open position
11. Top panel retracted to open position
12. Tonneau panel retracting downward, closing
13. Tonneau panel closed
14. Tonneau latch, retracted
15. Audible chime 2 times indicated cycle completed
So...Any suggestions?
