The computer in your Chevrolet car generates and stores fault codes based on the condition of the vehicle’s emissions system. When there is a problem with the emissions system, the “service engine soon” light will come on on your Chevrolet car. This will indicate the need to diagnose the exact nature of the problem and fix it. An auto parts store will diagnose the problem for free. A Chevrolet car dealer will diagnose the problem, but for a small fee. The advantage of having a dealership do the diagnosis is that you can better identify the problem using diagnostic software designed specifically for your vehicle, while the auto parts store diagnostic test device will give you a general idea of ​​what is wrong. (that is, it will). tell you various possible problems in the emissions system versus the exact sensor that has failed). Once you have fixed the problem, you must restart the computer.

Turn the key in the ignition to the “Key On / Engine Off” position.

Look for the diagnostic link connector on your Chevy Malibu. It will be under the dash on the driver’s side on the left side of the steering column.

Insert the OBD II code reader / eraser plug into the DLC. It is trapezoidal in shape and will only connect properly in one position.

Scroll the arrows to the “Read Codes” option on the OBD II Code Reader when prompted.

Read and write the codes on a piece of paper. Some codes may be what are called “hard codes,” meaning that repairs or more diagnostics will be required to correct the problem. Some “soft” codes can be erased, but they can come back after the instant messaging monitors of the computer system have gone through certain timed cycles. Save the codes on paper for future reference.

Choose the “Clear Codes” option on the OBD II Code Reader / Eraser.

Turn on the Chevy Malibu to make sure the codes clear. If they didn’t, or they re-activate immediately, it is most likely due to a harsh code that will need immediate repairs in order to rectify it. If they stay out for a day or a few days but come back on, repeat the procedure to see if the same code is waking up the computer. If so, that repair will need to be investigated or made in order to rectify it.
