The Honda PCX / Forza / ADV150 / SH Forums

Hey Mel, I just remembered that maddiedog provided us with the PCX wiring diagram it's right here: http://www.hondapcx.org/viewtopic.php?f=15&t=771

thanks all, I had already downloaded the wiring diagram and traced them as far as i could and they checked out fine.

the display seemed to start going wrong very soon after my last refuel so maybe the problem is associated with the fuel sensor?

How does the fuel sensor affect the speedometer and odometer? I havent followed the diagram all the way through yet, but it would seem to me that you should at least be able to see your old mileage on the odometer.

No reason apart from the fact that that fault coincided with a refuel. Also as the digital display also no longer displays fuel level

The more I think about it the more I think it is a faulty dashboard.

The 2011-13 123 dash is £65 on Ebay - then there is the nice electronic alternative

If it is the dash then I will be saving up for the kitico one :-)

Local dealer says that it wont be fixed under warranty as I have missed to services. He wanted £80 just to have a look at the problem :-(

Is Webike the cheapest site to pick up the Kitaco speedo at £225 inc shipping to the UK?

That's almost 10% of the bikes new price

Its a broken wire somewhere on the loom. I had this problem fixed under warranty so don't know a lot about it.Its something to do with the suspension going up and down and rubbing through the wire .

Damn, that is depressing as I have no idea how to go about checking that :-(

Can I check the current with a voltmeter where the loom plugs into the dashboard?

Sorry not really sure, it will be one of the wires to the speed sensor ,but you'll still need to take off some of the bodywork to see where it rubs. they told me that the rear suspension moves up and down and chafes the wire causing it to break.

Although you may be able to spot where the problem is by removing panels, a better way to check end-end continuity is to remove the battery (don't want any shorts!) and with panels removed, check using the ohm (resistance measurement) on a meter one end to other - if the wiring loom and diagram makes sense. May be a lot of work not knowing where things are routed, but once found, you may be able to lay a new wire in for next to nothing.

Thanks fungomerry, useful to know this - without 'something' reaching the dash, it acts dumb and shows nothing rather than zero or such.
