Fiberall OBD scanner is a miniature diagnostic tool for OBD2 vehicles. When there is a problem with the engine or the emission control system, the engine fault light will light up. In this case, you need to use an OBD scanner to scan the fault code to determine the cause of the fault light. Once the problem is resolved, it can be reset. This article will tell you how to reset the fault code using the OBD scanner.

What are the prerequisite steps to reset the code using OBD scanner?

The OBD scanner can almost provide you with information about vehicle faults, how to reset the fault code of the OBD scanner and what should be paid attention to in the steps of resetting the fault code? Next, I will briefly introduce the prerequisite steps to reset the code using OBD scanner:

①Connect the OBD scanner to the OBD vehicle diagnostic interface under the steering wheel. Turn on the ignition switch. Turn off all accessories.

②Press the "Analyze" button on the OBD scanner to analyze the engine's fault code. For safety, write down the fault code for future inspection and maintenance.

③Press the "Clear" button on the OBD scanner to clear the fault code. This step can turn off the fault light. Some OBD scanners have the function of freezing the fault state, which can record the data collected by the sensor.

④After the fault code is cleared, the data file will disappear. Some OBD scanners have an automatic mode, and the button displays "Yes" or "Delete", both of which mean "Clear".

What is the traditional way to reset the fault code using OBD scanner?

Regardless of whether you are using a Mercedes-Benz S500 or a Ford Raptor, you will still use the same connection to check the vehicle service code. Next, we will introduce the traditional method of resetting the fault code:

①First, you need to disconnect the battery and unplug the positive and negative cables. If necessary, use a wrench to remove the cable.

②Then, keep pressing the horn for 30 seconds to consume the remaining power in the capacitor.

③Wait 15 minutes and then reconnect the battery. After the fault code is cleared, the fault indicator will go out. For some vehicle-mounted computer systems, this method may not be useful.

④If the fault indicator does not go out after disconnecting the battery, it indicates that the car is seriously faulty and needs repair.

 

What are the precautions when using OBD scanner to reset the code?

Normally, the OBD scanner will always be able to read the fault code of the vehicle, but in some cases, because the machine may not be able to read the fault code due to a short circuit in the vehicle computer, the next overview is to use obd Notes on the scanner reset code:

①Remember to use the method of disconnecting the battery to clear the fault code will also clear the data of other vehicle equipment, try not to do this.

②The emission detector records that you have been reset, so the car cannot pass the exhaust gas test. Before the emission test, the car must travel at least 320 kilometers.

③If the fault code continues to appear and you do not know how to deal with it, you need to go to a repair shop. Experienced mechanical technicians can help you inspect the car and reset the fault lights.

④If the problem is still not resolved, the responsible car repair shop will not reset the fault light because it is illegal. Only after completing the diagnosis process and judging the fault, you can perform this operation when necessary.

⑤The engine failure indicator lights up, indicating that there is a problem with the car, so it is not safe to reset without knowing the problem.
