Disconnect the Negative Battery Cable

If you don’t have any specialized equipment on hand, the easiest way to reset a check engine light is to disconnect the negative battery cable and leave it unhooked for a minute or two. This will allow your systems to reset, and your check engine light should go off as soon you start to drive through Guaynabo or Rio Piedras. Here’s how to reset your check engine light by hand:

1. Put on safety glasses and gloves, and turn off your ignition.
2. Get under the hood and locate your car battery. The negative terminal will usually be marked by a black cap and/or a negative (-) symbol.
3. Use a wrench to loosen the nut which secures the cable to the terminal. Remove the connector, and hold it to the side for 60 seconds or more.
4. Reconnect the cable using your wrench.

It’s also possible to use a Toyota scanner to reset a check engine light. If you’d like to pick one up and find out how it works, get in touch with our parts department today.
