My speedometer is only working intermittently. 2007 Alphard. I know this topic has been brought up before but I am struggling to see the same thing that others have posted. I have removed the speedometer instrument cluster and this is what I see. I’m wondering if I’m looking in the wrong place or maybe there’s something here that might be an issue. Any help would be much appreciated. 

Hello Thomas that red thing is your converter chip these are supposed to be soldered in I see yours are connected wire connectors that’s a big mistake by the person who fitted it if I was you get each wire connection checked could be a loose wire I also notice you got a wire cut and doing nothing have a look see if that’s come off somewhere also chip could be faulty 

Thanks for your help. I’m not sure why there is a wire that has been cut, it must’ve been like that before I was having issues with the speedometer, I will ignore that for now! I guess I should focus on the converter as the connections seem secure.

Hi Picasso, please could you help me out a bit further? I’ve checked the connections and, although they are not soldered, they all seem secure. Would you recommend replacing the chip and, if so, is it the CK-UN-09 that I should be purchasing? Many thanks 

Yes it’s a ck un 09 chip became what you buy as there are cheap Chinese ones on eBay 

Thank you 🙏
