This is done at your own risk! Any ECU replacement MUST have the same part number that you are replacing. Key ON Turn off all accessories (radio, blower motor, etc.) If you have a old or weak battery, make sure to add a trickle charger to make sure the battery does not die Obtain a jumper...

I already have same ECU part number. The problem with these steps, I have cable in pin# 4 but no pin in number 13. There’s only 14,15 and 16.

 

did you ever get this sorted out? i have same issue. Did you program yourself or use techstream?

 

2020 is not still under warranty?

 

Where did you get the new ECU from?

 

Your are typically either going to have to go to the dealer or get a device that is capable of resetting the VIN on the ECU to match the car. You may even need a valid copy of Techstream.

 

Yes, like the others said, you need to program the immobilizer ECU with TechStream...
