Dashboard doesn't work - 2019 pcx 125

[tommypl88]

Hi guys. I'm a owner of 2019 black pcx 125 with 9500 km done. I'm really satisfied about this scooter but today, unfortunately, i had an issue: the display (completely digital) doesn't work, is dead, so i can't check speed, fuel level, clock and, also, notify status about direction lights (green left/right) and start/stop (green A) are always off. High beams and ABS status, instead, works well. Any idea? Apart this problem, scooter goes well without any electrical/mechanical problems. Thanks in advance

Check fuse for the dash, or the communication/power cable.
It should power up, and some of the data is transmitted through a bus communication from the ecu. However there are some stand-alone safety signals (E.g. ABS feedback is driven directly by the ABS ECU.
I can't remember if these are pulled to ground, or powered to be on, but I'd guess the later. Depending on the previous, either ground or switched power are compromised at the dash.

Interested in this subject. My 2013 dash BACKLIGHT doesn't come on anymore. Wondering if there's a fuse I could easily replace without ripping the whole thing apart.
