March 8, 20215 yr Hi everyone Cheers for the addition to the forum. I've built a few cheap conversions with front hubs a long time ago and did Bafang mid drive a few years back. I'm now trying to help a mates wife with her bike as the ebike "expert" in our social circle! (I'm so not but all is relative!) She has a ebco m45 which is playing up and won't work. The basic led panel is clearly flashing an error code sequence but I can't find an online manual to decipher it for love nor money! Might anyone be able to help me? I Thank you Naz

March 8, 20215 yr Author This is the only panel and it flashes a 4 shape sequence including H and 0 Ill try a video in the morning if the site takes them
March 8, 20215 yr Chinese parts do seem to have very hard to track down error codes. If you're very lucky, it'll be a dodgy lead (check, especially the ends) or corroded contacts in the connectors (use contact cleaner and then dry). If not, check the battery for voltage and if that is ok, look for water damage to the controller.
March 8, 20215 yr That looks like a Tranzx DP27 display; it's a CANbus system. Apart from the mini USB socket on the display, there's a fault diagnostic socket behind the end panel on the rack battery for connecting to a dealer laptop. AFAIK, the entire bike was made by Tranzx (IIRC part of their "Mavis" range) and only branded Ebco in the UK market. My guess is you'll probably need a dealer to run their diagnostic tests.
March 8, 20215 yr Instead of the Ebco manual, you should be looking for the electric system manual that comes from TranzX. This system is also used in other bikes, like the Raleigh Spirit. I found this guide to TranzX error codes: https://raleigh.zendesk.com/hc/en-us/articles/360001420613-Error-codes-on-tranzx-systems If you can figure out the error code, we might be able to interpret it for you. That page has some other useful links.
March 8, 20215 yr I found this guide to TranzX error codes: https://raleigh.zendesk.com/hc/en-us/articles/360001420613-Error-codes-on-tranzx-systems Pretty sure those codes only apply to the DP15/16 LCD display (not the OP's DP27), which can be used to run basic diagnostics on the display itself without the laptop. The Tranzx laptop diagnostics are very Bosch - display, motor, controller, pedal/speed sensor, battery BMS and it prints out a full hard copy report... and uploads new firmware too. There is a link on the Raleigh site to access/download and install the Tranzx Logix diagnostic software c/w passwords, but I don't think that link works anymore. Halfords used to sell the M35/M45 I think, so they might have it.
March 9, 20215 yr Author The tiny panel flashes "H" then "o" and then "t" But not in that order, o then h then t
March 9, 20215 yr Author Are you sure it's not 04E? Pretty sure but I cannot get the video I took to upload. The definitive order and capitalisation is as follows 0 then H then o then t
March 9, 20215 yr At the risk of asking the obvious, did you check the battery voltage (in case the bike has been unused for a while), and the motor connector etc is properly inserted? It's an F15 front hub isn't it? I'm personally doubtful that you're going to get any useful diagnostic info from the limited 2-digit "88" LED display as the DP27/motor/battery/controller all relies on CANbus comms. The DP16 - being a "KT3 size" of LCD - does do proper error codes, but even then it's simply "Motor fault - replace the motor". It's not really that helpful! If the "0Hot" is some sort of meaningful error code, you could try emailing J D Components' technical boffins (Tranzx's main depot/service centre) in Frankfurt?

Voltage is fine on the battery at 41.8 and isn't losing voltage if left overnight. So I think it's ok It is a front hub, yes. And I've tried the usual connections (well unplug, clean and plug back in!) Thanks for the tip on the email to boffins, great idea
March 9, 20215 yr Halfords sold EBCO bikes: https://www.pedelecs.co.uk/forum/threads/ebco-ebikes.36289/ ... might be worth asking if they have the diagnostic software. There's also EBCO: http://www.ebco-ebikes.co.uk/
March 9, 20215 yr Other than talking to Tranzx or hooking the bike up to the diagnostic software, I'm out of ideas. But I wonder if your DP27 does the little boot-up "dance" first before displaying "0Hot", or does it just go straight to the error?
March 9, 20215 yr Pretty sure but I cannot get the video I took to upload. You can upload to Youtube and link, if you wanted.

But I wonder if your DP27 does the little boot-up "dance" first before displaying "0Hot", or does it just go straight to the error? Really appreciate all the help from everyone! Actually it does do the the little dance first! But only holds on the initial 0 for a few seconds before going into the error code on repeat Sounds like I need a dealer or the diagnostic software on my laptop to get much further
March 10, 20215 yr But only holds on the initial 0 for a few seconds before going into the error code on repeat Lockdown boredom... I'm still here! Your mates' wife may be in luck... This page says the M45 was only introduced in 2018, so it can't be too old - maybe under 2 years old?: Products | EBC Bikes (ebco-ebikes.co.uk) Rifling through my draws, I've found an Ebco manual that includes the M45 model. It states: All electrical components inc battery are covered with a 2-year warranty (battery limited to 500 charge cycles). If error codes appear on the display, refer to the error code list (in the manual, a similar but shortened version of the one vfr linked to above - nothing about "0Hot" though) and contact your dealer for diagnostics. Elsewhere, FAQ says "the motor can overheat on very steep hills, but the built-in heat sensor will automatically shut down the system before any damage can occur to the internals of the motor". As your DP27 is booting-up properly, do you think your "0Hot" message may mean "0" mph, then "Hot", as in an overheat event occurred? Okay, so I'm clutching at straws here...
March 10, 20215 yr A reset might be an exclusive preserve of the diagnostic software. If it's still under warranty, ignore the following: The PC Repair part of my mind, is wondering if this DP27's memory can be reset by removing it's internal battery (if it indeed has one) for a minute, then replacing, or alternatively clearing the enduring terrible memory of it's hypothesised traumatic overheating event, by shorting two CMOS memory wipe pins (if indeed is has those) on it's internal board?
March 10, 20215 yr Author It's not under warranty so maybe I'll be disassembling the dp27 as next step The hot motor trauma event theory is a good one!

Blast, having just taken the dp27 off the handlebar it is apparent it is a sealed, glued unit
March 10, 20215 yr If we're buying into the heat-stress theory, I accidentally omitted a bit... It actually says ""the motor can overheat on very steep hills and under heavy loads, but the built-in heat sensor will automatically shut down the system before any damage can occur to the internals of the motor". Given the way the rear-rack battery is robustly supported, you can image a second body riding shotgun and exceeding the stated 120kg max payload. I'd avoid trying to manually reset it for risk of bricking it - that would be expensive, whereas all it likely needs at the moment is hooking it up to the diagnostics and resetting.
