How to Reset a Vehicle's ECUs Without a Scanner

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

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 Check the Oil Level on a Jeep Renegade?

To check the oil level on a Jeep Renegade, you need to open the bonnet to access the components inside the engine bay: on the lower left side of the engine block, you will find the dipstick for checking the level. This should be pulled out and thoroughly cleaned with a cloth: once cleaned, reinsert it back into its tube and pull it out immediately after. This way, you can check that the oil mark is between the minimum and maximum levels; finally, you can place the dipstick back in its tube.
