Yes.
The comms channel that 'was' used to reset the platform was the handlebar physical interface, a CANBus interface.

You guys are talking over my head with all these comms. Would any of this be useful for a fix/diagnostics?

I may try a new handlebar/csb as Mattk suggested. Will the original keys that came with the unit work with a new handlebar/csb assembly? I don't know if the info for the keys is matched in the motherboard or in the handlebars. Or do you need the keys that come with each specific handlebar?

Also, it went to a beep again without any display readout. Disconnecting the cables and refitting them brought back the wrench. I just find it curious.

Things are hard to diagnose remotely.

My best guess, is that you have at least 2 problems.

Problem 1
Batteries are likely old and bad.
To verify, borrow a set of batteries, fit them, and see what happens.

Problem 2
Red wrench.
This is a serious problem, with no solution ( that I know of ).

Good Luck

I've sent you a PM of the contact into for a person who I believe can reset your machine. Good luck and please let me know if there is success.

I may try the NiMH battery swap first. Given the packs are 17 years old and seems to have never been used much, they likely are drained. Eventhough they test at 40v per side with a multimeter, and it did somehow turn on at one point recently for a few days.

Just for others' future reference, when plugged in for days and charging, I would get the red wrench when the keys were introduced. When I pulled the charging cable, it immediately went to a single beep with no display readout. When I plug in the charging cable, unplug/plug the stem cables, it goes red wrench again.

Anybody in Chicago with working NiMH packs for a i167?

Default What error code is showing on the UI screen?

I've attached a jpg from a Segway HT service manual that shows 4 of the error displays in conjunction with the Wrench symbol.

Is your i167 telling you that you have a Platform Fault, an Unknown Fault, or a Front/Rear Battery Fault?

If the problem is an Unknown Fault then it is one of the following possibilities, and you can track it down and resolve it by swapping on known-good parts:

(a) a faulty Handlebar
(b) faulty Handlebar cables between the handlebar and yellow & black plugs, or faulty plugs
(c) faulty CSB
(d) faulty cables cables or plugs (yellow and black) rising up out of the CSB
(e) faulty battery pack(s) - where the fault is of a different type than indicated in the attached file

If it is an Unknown Fault then this is good news. It means that your PowerBase (i.e. platform) is still OK, and all you need to do is swap on the appropriate known-good part(s) to make your i167 fully operational again.

If it is a Platform Fault then I am sorry to say the news is not good. Your i167 probably encountered a fault that it has determined is sufficiently serious that the device needs to be serviced by a Technician, as was the philosophy in the early-2000's. We called this a "latch fault" in that the unit won't start until the fault logs are cleared. If there is someone out there who can "unlatch" your PowerBase then you have a chance of fixing it (depending on the cause of the fault or upon what component is faulty).

I no longer have the ability to unlatch Gen 1 PowerBases, and do not know how it can be done anymore. But I'd be interested in finding out!

My guess is that when you were riding hard on weak battery packs this caused a condition that was logged as a "latch fault". Did it happen when you hit a big bump, putting the machine under heavy load? I remember this happening to me back in the days of dodgy NiMH packs. Simply by unlatching, the machine would then work fine again (with good battery packs).

Unfortunately, on Gen 1 just about every Platform fault would cause the machine to latch. It wasn't really designed for in-field service, unfortunately. Whereas on Gen 2, a smaller percentage of faults would cause a latch, enabling certain faults to be resolved simply by swapping faulty components for good ones.

It is showing the "platform fault" error. It was showing this same display when I bought it for nothing, but after a day of charging, pulling/plugging the cables, lots of key pressings, it somehow came back to life. Then I was trying to drain the batteries so I ran it for 10-15 minutes at high speed and it turned off on me.

I do have replacement handlebar/csb units on the way (original cables were shredded down to the foil). They have the elcon cables this time instead of the old ones. I'll see if that does anything. I just find it curious that I had the 'platform error' originally and somehow it started up.

I think you are most likely correct about the 'latch' issue. I have a lead on somebody who might be able to help with that area. I'll share the results when I have them.

Please followup on the resolution to the "latch" issue

I'm sure there are hundreds of people looking for a solution to this problem.

I just installed a different csb and handlebars. These cables are in good condition unlike the originals, and the new ones have the elcon connectors. I'm waiting on a deep battery charge at the moment. But it's interesting that the readout already went from 'platform fault' to 'unknown fault' with the new parts.

Question at large: Does anybody know if the keys are tied to the platform (motherboard) or the csb or the handlebars? I have all the new and old keys, I'm just unsure which to use at this point.
