Checking The Customer's Spare Parts - The Shiny ECU Turned Out To Be Damaged !!! - Part 1

This time I have the opportunity to share my activities in checking goods sent from customers. Starting from opening the package, checking the condition one by one, testing it directly on the car and also servicing the ECU, then testing it again and wrapping it to send it to the owner.
Who knows, if any of your friends are experiencing the same problem, you can consult me ​​via Instagram DM.
