Diode replacement

Hi guys!
new here, but been following EEVblog for a while now.
I have a Volvo computer to repair (from an excavator or similar) but I can't find info on the burned component.
It looked like a diode obviously... might be a zener? but without info, it is hard to order a replacement component. it is about 6.5mm overall length and 3.5mm width.
diode test (multimeter) gives me about .570V forward and 3.20V backward on a good one.
any help here to identify/test/find a replacement is more than welcome.
I added a picture of one of the good one.

thanks!!!

Welcome to the forum......
Could it be a Onsemi MURS1504? https://www.hotenda.com/marking-code/search/list/RGG.html


 Data sheet attached.

Are you measuring this diode in-circuit?
mvautodiag:
yes in circuit.

I have order 10 of each MRS1504T3 and NRVS1504T3G. will compare in circuit once received for similar reading compare to the other one.
I guess comparing using my curve tracer will give me a better idea than just using a multimeter.
will let you know probably next week.
thanks!!
