[ECM 89661-08061-84 has bug]

Hi,

Has anyone gotten this problem?

Is ECM 89661-08061-84 glitched? If so, how do I solve this problem?

Thank you

Here is my story,

I bought an used car 2001 Sienna LE without engine immobililzer system.

I wanted to upgrade my ECM (89661-08061).

The dealer installed this new REM ECM (89661-08061-84).

However, with the new ECM, they were not able to start the van.

Then he put back my old ECM to the van, and the van could be started again.
