Hall sensor removal question
- Thread starter john-e89

Good news and hopefully good news.
After removing the SmartTop the fault returned so at least I know that is not the cause.
A further inspection revealed my pin on one connection had not fully engaged. Reset it correctly and also I had both sensors fitted the same way. I reset them so the wires are facing each other and going towards the middle of the ram.
Another test drive this time with no errors. I will monitor and report.

So even though the codes were pointing to the hall sensors, after replacing them, my problem persisted. I would get random bongs with dash warning when driving. My roof worked first time every time. It was just the constant bong.
Usually when accelerating or going round corners. So I invested in genuine microswitches from the dealer.
part numbers 54377228585 54377228586. £110 for the pair. These are located in the boot either side on the forward hinge mech.
It took longer to get the trims off to replace them. I did repin the new pins into the old connector as the new part has an updated plug which doesn't fit. I did have to cut a slot on the retaining bolt as the Alan head was too soft to overcome the loctite. A large flat screwdriver did the trick.
So far so good. Time will tell. On a positive side. When I checked the resistance of the old parts, one had intermittent readings which fluctuated. This could explain the random bongs. The other side was working the same as the new parts. Hopefully job done. :driving:

Hate to resurrect an old thread, but I see you're still pretty active on the site. Can I just ask, did this fix your issue?
I'm getting exactly the same problem, replaced the 2 hall sensors and am getting the same error codes that you had:
00A698 Rear-end module open during driving
00A69E Speed in soft top intermediate position higher than permitted
Just wanted to make sure this fix worked for you long term before shelling out for microswitches.
Thanks

I thought that initially they were related to the hall sensors, but after replacing them both I cleared the codes and they came back.
Previously I was also getting the hall sensor specific codes, A691 and A696. These have not returned, only the 2 I previously mentioned, so it seems like there is something else going on....

Thank you, this is why I was wondering if the microswitches are to blame. I just wanted to check if they solved the issue before shelling out on the parts

In relation to these 2 codes (00A698 Rear-end module open during driving & 00A69E Speed in soft top intermediate position higher than permitted) - I note they are consequential errors as opposed to pointing to a specific fault. Does this mean the cause could be anything from hall sensors, microswitches, bad wiring etc? Is there any way to narrow this down?
00A69E Speed in soft top intermediate position higher than permitted
My current understanding is, that this code only occurs if the roof is not locked, but the car is moving with a speed of more than 3 km/h. Maybe this understanding is not exactly correct regarding the speed limit.
It's definitely not the "speed" of the moving roof shell or roof package while opening or closing.
Said this, I wouldn't understand this code if the car hasn't been moved after deleting all fault codes.
Important:
The ignition has to be switched ON while deleting all codes!

Ignition is sufficient.
With a good tester (INPA, Foxwell, others) you can check the live status of these two MS on the couplings.
Important:
Both microswitches have to be in sync, pressed or unpressed, locked or unlocked. If there is a short deviation of more than a ³/⁴ second, both have to be renewed.
Only these 2 MS are responsible for the locking status, not the HS.

Ah ok. Yeah I'm using INPA. Sounds like these might be the culprits then, think I'll just bite the bullet and renew them, they are likely to need doing in any case as I don't think they've been touched previously and the car is 15 years old.
Would I get any other codes specifically related to the microswitches though, or not necessarily?
