The car loses power when it drives pass 120 km/s speed

Hello,

This sounds like you could have a problem with a dead battery. Can you get a voltage reading across your vehicle's battery terminals using a Digital Multi-meter [DMM] for me?If you are unsure how to use a DMM, here is a guide below explaining how a DMM is used:

Thank you Sir, the voltage reads 12.42. Electrical function still works properly.

Hello again,

Okay, so this could possibly be a problem with your vehicle's starter relay, which is located in the Battery Junction Box [BJB], by your vehicle's battery. In the diagrams down below I have included a wiring diagram of the starting circuit in your vehicle as well as the diagram and callout of the BJB for your vehicle. Here is a link down below for you to go to explaining how to test a relay:
