Looking to bench test a Instrument cluster - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Wryvin · 09-18-2020, 11:48 AM

I did some work to a test instrument cluster and want to test the part before I put it back in a car. I was browsing through the schematics for the 2013s, and haven't found anything yet.

I was curious if anyone had already figured this out yet. I searched the forums and what I found is mostly just LED swap jobs and re installations. I will keep looking through the schematics, and if I find it I will update here.

Maybe a silly question, but why not test in the car? You don't need to put it back in, just hookup the connector to it.
I would imagine a test bench would need to supply much more than just 12V to get anything meaningful from the cluster.

I haven't taken mine out of the car yet. I wanted to do quick ops check, without swapping them out. My ESD workbench isn't at home so I just wanted to test while I worked it.

I have a programmable Power supply that can support this, I have used it for much larger projects.

I'm pretty sure you'll want the Combination Meter, starting at page 326 here: https://www.ft86club.com/files/BRZwiringi.pdf. That would be connector D7, a straightforward 2 row 40 pin connector. Looks like it's mostly controlled via CAN, so not sure how easy it would be to get it working outside of the vehicle.
Good luck, though!

Thanks I'll check that out. I really just need power, shouldn't need any of the signals.
