Driving along today I suddenly got a warning chime and the dash indicated the tailgate was open. Stopped and checked it, all OK so carried on. A few miles later the same thing happened but this time the warning disappeared on it's own so I didn't stop immediately, and again all was OK at journey's end. I figure the sensor/switch is getting a bit sticky or needs some adjustment, but I can't see where it is. There's no obvious push switch pressed in by the door, which is what I was expecting, so I figure it's somewhere inside the latch mechanism. Anyone got any ideas?

I don't know your model but this parts diagram doesn't help ?

could just be sticky, perhaps a little squirt of WD40 into the lock might lubricate/clean it out.

Thanks. My French isn't good, but I don't see anything in there that might be a switch or sensor.

In principle yes, but I want to find the sensor/switch rather than spray randomly. And I'm not sure I'd use WD40, that isn't really a lubricant and is likely to make it more sticky rather than less. Some carefully targeted 3 in 1 or similar is what I had in mind. But where?

Found this on Fit Freaks, the US Jazz/Fit forum.
I removed the tailgate plastic cover from the back and eventually found a 2-pins connector near the tailgate lock assembly. Unplugging that connector shut off the doors open light in the dashboard and shut off the interior lights.

Sometimes I get the tailgate open warning after I think I’ve closed it, and I clear it by re-opening and closing it more firmly. I assume that the catch had not gone fully home the first time.

I occasionally get that too and have to slam it more firmly. I assume there is a sensor thats a bit more sophisticated than the old fashioned plunger switch that could sometimes be adjusted by screwing it, or a strike plate, in and out. But I don't know where the switch is or if its adjustable.
But if its sophisticated electronics maybe the sensor can be affected by dirt and any debris, such as leaves etc. . Or am I the only one who sometimes neglects to carefully clean the boot shut area when washing the car ? :-[
Possibly the solution might be a slight adjustment/repositioning of the catch mechanism so the boot is held more tightly shut , rather than the switch.

In my case, the tailgate is definitely tightly shut - it's been checked multiple times, including slamming really hard.
Did a 50 mile round trip yesterday. On the outward journey, the warning came on 5 or 6 times at random intervals. I didn't bother to stop and check because I knew it was tightly closed at the outset and wasn't making any rattling noises, and it was still tightly closed on arrival. On the return trip, not a peep from it, everything normal. So it looks like a sensor problem rather than a latch failure. Grrr, I hate intermittent problems!

Especially as they rarely fail when the garage investigate.

Egg on face time ... the dashboard warning I was getting is nothing to do with the tailgate, it's actually telling me there's a fault with the parking sensors. Didn't really suspect that until I got a similar indication but with all four corners of the car lit up at once whilst driving along. Car's booked in to the dealers in a couple of weeks, meanwhile I just have to keep the system switched off (but remember to turn it on when I park!).
-
Been in to the dealer today. £50 to diagnose the problem, which turns out to be one of the rear sensors has failed. Cost of replacing that is around £200, and the nearest spare is apparently in Belgium. Arguably one could do without the system, but it is quite useful and a continually pinging alarm is an unwelcome distraction when driving. So that’s another visit after Easter.

Belgium is the Honda parts store.
Bit of a pain, especially with the often slow border.

Slow moving parts will be in Belgium, fast moving parts eg. Service parts and higher demand will come from Swindon.

Still a Swindon Honda presence then ?
