HOW DO YOU REPLACE THE PCM?

1994 Lexus ES • 143,000 miles

I need to replace my pcm/engine control for my 1994 lexus. It looks as easy as just plugging in the replacement and turning on the car.


Do I need to program or disable anything for it to work?

thanks so much!

It needs to be reprogrammed as well just not replace it.

Does it have to be programmed to match my VIN?

No but it needs to be reprogrammed for your drivetrain
