Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.

If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

I was really impressed with how straightforward the installation was on this ECM for my 2012 Toyota Sienna. It arrived quickly and matched my VIN perfectly, so there was no extra programming needed on my end. The engine runs smoothly now, and I appreciated the clear instructions that made the whole process hassle-free. Definitely a reliable replacement part that saved me a lot of time.
