How to Reset All ECUs and Control Modules in Your Car

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

Video tutorial

In this video, we will see how to reset all the control units in your vehicle; this method is valid for almost all cars in general and corrects most errors, including fuel adjustments, incorrect idle, and faulty sensor values. You will only need a jumper.

Start by disconnecting the negative terminal from the battery, isolating it, and connecting the cables to the terminal you removed and the other to the positive terminal; leave it like this for a while until the positive circuits charge into the negative and ground out. After about 20 minutes, reconnect the negative terminal.

Turn on the ignition and allow the ECU to learn the new values for about fifteen seconds.

Then turn off for a moment and directly start the engine, leaving it running for five minutes so it can find its ideal idle. Then try to engage the gears (this is an automatic gearbox), and the gearbox will adapt to the values during use.

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.
