Looking to bench test a Instrument cluster
 

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.

@Wryvin

hey mate, how did you go with this?

I am hoping to run mine outside of the car too. i want to make some changes and test before reinstalling. did you manage to get yours running?

Any chance you have a pinout/diagram for the pins on the back on the unit?

Cheers

Hello, bumping this old thread because it pops up on a google search, I was able to bench test my cluster with just a 12V input.
This will illuminate all the bulbs (lamp check mode) and displays (along with showing cluster mileage)

You need to do the following;
Pin 1 - Input 12V
Pin 2- IGN
Pin 20 - GND


Bridge pin 1 & 2 with +12v

When looking at the back of the cluster (round side to the sky), pin 1 is the very top right, pin two is the next pin to the left of that (top row).
Pin 20 (ground) in the very top left pin.

Hope this helps others.
