2010 XKR, Convertible top will not function.

Push the top down button and nothing happens. Front windows do not lower, rear windows do not lower and the top does not move.

I tried holding the button for 3 minutes, no change. Tried both up and down buttons (same switch forward and backward.)

I have reset the trunk luggage cover and no change. (Additionally there is no message in the display regarding this.)

Seems like there is no power to the switch. I checked fuses F8, F30, & F32 in the rear seat compartment, all are good.

There is no sounds when I push the switch either. The lowering sequence simply does not begin.

I drive the car year-round and have not lowered the top in ~6 months. (It was working fine the last time I used it six months ago.)

I hate to think a dealer visit will be required, but I do not have a code reader.

Any ideas on what the cause may be?

 

Suggest you use the search box at the upper right hand corner of this page. If you don't find anything there, then pm white xkr or go to the website: TheJagWrangler - Home - About Us. The gentleman, Steve Klonsky, that runs it is an expert on XK convertible tops and has invented and sells a remote top controller which is probably the best accessory you can add to your XKR. Additionally he is very helpful.

 

Either do a manual reset on top or reset the windows up/down three times on each side.

 

JagRag,

I know that this may appear to be a stupid question, but you didn't say if the engine was running while you were trying to get the top to operate. I just want to confirm that it's not caused by a low battery.

I agree with jlpatton for a first step; Reset both front windows. See what happens.

 

Yes the engine was running prior to and during pushing the button.

 

I did try that once, but will try it three or more times on each side.

 

AND a Hard Reset? Ya never know...........

 

I haven't tried the manual reset yet, but will try it. It seems more like an electrical problem as the windows do not lower.

 

May try that, but it is a pain to get to the battery terminals.

 

Yeah I'd say skip the other things and START with the hard reset. Kind of a pain with verts but well worth it in this case.

 

JAGRAG - What was the problem? Please share!

 

The trunk luggage cover misplaced and trunk open are two reasons for inop top.
First try closing the trunk lid a little more aggressively than normal.
If no joy, try completely removing and replacing the luggage cover.
I have experienced the 'open trunk' failure without a message on the IP.

Please let us know what you find.

Nothing to update at the moment, as the CV19 closures have prevented me from getting it into a shop for diagnosis and repair.

 

RESOLVED

So the top issue has now been fixed.

Long story short it required 2.3 hours charged labour with my mechanic to fix the issue.

I wasn't unable to get the car into a shop until today because of CV19.

In the past week or so I imagined simply tearing out all the items related to the "power" part of the roof and lightening the car by perhaps 50-60 pounds. Then I would fashion a tool or two to make manually opening the roof a quick option. Then forever on, if I wanted to open or close the top it would simply be a manual function.

Alas, common sense prevailed and I waited out the delay. It was made easier as the weather here still isn't conducive to open-air driving.

So, my mechanic told me that when he tried to read the codes, he could not access the convertible top module with the reader. It was not communicating with the rest of the modules in the car. Note, I had the main battery in the car changed about 3-4 months ago because it had a dead cell, and left the car completely without power 4-5 times. (This may possibly explain the loss of communications between the top module and the others.) As I drive my car year round, the top had not been cycled in about 4-5 months.

Next the mechanic removed the rear seat to access and remove the top module (I never knew the seat would need to come out, but so be it.) He then tested the connections to the module, and the module itself, & all was good. It was getting power, just refused to communicate. (As a side note he told me he had priced a new module as a precaution just in case mine was "bricked".) The cost was ~$1,100 and would have been at least a week to ship.

Then he powered up the module on the bench (don't ask me how as I wasn't there), and he said he performed a hard-reset on the module itself. He then reinstalled the module in the car, and voila, it worked again.

I didn't ask too many other questions, as I considered it a relatively "cheap" repair for the problem. Now perhaps he could have just done a hard reset from the battery cables and gotten the same result. (I didn't ask him if he tried this first.) Who knows for sure, and it probably would have only save about one hour of labour.

This probably will not help the others that have recently posted about convertible top issues. But my mechanic did roll his eyes and cuss about all the electronic modules in these modern cars.

 

Good to hear. I'm glad you got it fixed without too much expense and hassle. I thought you would have tried the hard reset to drain the module, as suggested in this thread. Yes, cars today are loaded with electronics. Future cars will have a lot more sophisticated AI driven processors and electronics to self diagnose problems like this.

 

I win! Post #8!
Anyway, I glad for you that it was not the monster that I expected it to be. I thought your module was a goner, and at that $1,100, that would have sucked.

 

Why didn't you try a hard reset as suggested yourself?
It's a 10 minute job!

 

I'm too lazy, too old, no tools, nowhere sheltered to work on the car, foul weather, no code reader...I could go on, but I probably should have stopped at too lazy.

 

After having my 2010 XKR for two weeks, I was exploring the battery cavity etc. to put in terminals for a C-TEK battery maintainer. yesterday I converted the clip on terminals to the permanent ring connections. Last night I was going to put the top down and it would not go down - just the rear windows.

I pulled over, turned the car off and tried again and noticed the luggage compartment error. After coming across this thread, I wrestled with it for 15 or 2o minutes and finally got it in correctly so now it opens again.

Thanks one and all again. I was a very unhappy camper for a bit. Now if I could get the intermittent amber light warnings and tire pressure warnings to stop I would be all set.
