How to Reset a Vehicle's ECUs Without a Scanner

Model: (Various brands) Various
Part: Warning light – error code

Video tutorial

In this video, learn how to reset a vehicle's ECUs without the aid of a scanner. You will only need a key to disconnect the positive and negative terminals of the battery.

The concept is that without power, the ECUs will lose their memory, erasing everything stored. Now take the battery charger, connect one of the poles to the negative terminal, ensuring it does not touch the battery in any way, and the other to the positive terminal (again, wrap the pole with a cloth so it does not touch the battery).

Now leave the vehicle to rest like this for about 30 minutes, or longer if you are not in a hurry. When you reconnect, all codes will have disappeared.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
