combination meter repair - DIY

I thought I’d post an update to my combination meter story. I installed the combination meter yesterday. I took my time and didn’t encounter any problems. I very carefully removed the dash vents and luckily they didn’t break. I followed the video from BoulderHybrids on YouTube. He really did a great job! When I tested the meter it worked fine so I put the rest of the dash back together and went for a drive. It didn’t take long before I noticed that the mileage on the odometer was stuck. I was pretty upset thinking I would have to take the dash back apart but I decided to first check and see what worked and what didn’t. To my surprise everything else worked. The trip odometer’s worked, and the maintenance reminders worked. So I think it will be ok. I was mainly worried about knowing when to do the maintenance. The mileage isn’t accurate anyway so I guess it isn’t that big of a deal. I set a personal reminder on the maintenance screen to let me know when the car reaches 300,000 miles. Just thought I’d post a quick update and thank everyone for all the replies and suggestions.

 

This thread is like 8 years old. My 2009 Prius with 204000 is now having these problems and wanted to know if anyone has update on these links to capacitors and wanted to know if the process in fixing the problem the same steps currently.
According to this tech you need to replace 3x capacitors and 1x motherboard regulator chip.
It seems the link for 330uF link is a link with a minimum order of 500x capacitor and I only want 2x just incase I mess up on my solidering. Can anyone shed some link to this old thread.

Thanks,

Bro you have been on this site for 4 years still cant figure out the Search Forums?

Yes, why would it change?

There are other places you can buy in smaller quantities. Mouser is one that come to mind. There is at least one other that can be found in this thread. Just use the information in the product specs in that link and buy an equivalent component.

 

I usually look for parts in this order, but will admit it is mostly from habit: Digikey, Mouser, Newark.

 

The links give you the manufacturers parts number. Search those on digikey/mouser etc. If they don't have stock, the links have the dimensions, uf, voltage and temperature. You can try other manufacturers like Rubycon, United Cemicon- quality brands carried by digikey/mouser. Use digikey/mouser parametric search tool. If you are not in a big hurry, aliexpress or Electronic Components Distributor - LCSC Electronics will have something. The most difficult part of the job is getting the cluster out...

 

After 10 hours and a few broken vent trim. We have her back together.

SM-A536U ?

 

WOW!!! You must have had some struggles. But, in the end success!!

BTW, where I was working part time, that vent cover on the left of the MFD was called the "money vent." They almost always break or were already broken. I've had some of them crumble like sugar candy. There was one that I managed to get out unbroken and, as I held it in the palm of my hand, it broke into three pieces.

 

Wow, that was hellish! My 05 is a base model. Must have pulled the dash apart a half dozen times upgrading the MFD to add backup camera, no breakage. The instrument clusters for the bad caps and then upgrading the cluster from an 09 donor car. Had to pull that twice to get the odo chip programmed properly, that meant having to unsolder the VFD twice. The 09 MFD has bluetooth and a microphone needed in the overhead light console. I attempted to wire that up with the JBL stereo, also from the 09 donor, but turned out I needed the remote amp that would have been under the passenger seat. Thats where it will stay. Now I am waiting for a yabo cylindrical NiMh battery pack(over priced for such old tech IMO, $2KCAN). My Headway LiFePo4 pack cannot handle the regen current, over the last 3 years I've replaced about 10 cells. The fun never ends... cheers
