+BM pinout on newer 1UZs

[Gonzalo Bravo]

I got in my hands a 1UZ VVTi that looks the "newer" ones, that has the newer type of coils (like 3UZ, 1GR, etc) and the ecu in the engine bay with the harness leaving the engine at front.

Does this ECU use the same pinout of previous ones? (3A590)

I have doubts with +BM and Immo plugs, that based on other post is in different location, but engine starts with a non immobilized ECU but do not accelerate. Any idea?

no the -3a590 ecu is different and is unique

I had to make an extra bench tester for a 3a464 ecu cause nothing worked
using my main 1uz vvti bench tester
I got a vid of this ecu all running on my bench with lights pulsing etc etc

I removed the temp sensor (B/R wire) pin out of the 3A590's connector. Who knows where the pin goes in the 28 pins' connector? My pinout only shows tranny pins plus RL, WFSE, LCKI and MOPS.

I removed the pin by mistake actually!

pin MOPS (24) is oil level and temp sensor, but it isn't needed for engine ECU. It's just forwarded to instrument cluster
