The second generation called ODB2 Scanner (It is managed with the OBD2 standard which is very extensive and is associated with other standards such as SAE and ISO) are used for subsequent vehicles of the year 1996.

In the early days of the car scanner, it only showed or showed the error code diagnoses of the few electronic parts of the vehicle and they were used jealously and with privacy by the certified workshops of the different recognized automobile brands in the world. The handling of the scanner was not very complicated and should only have at hand the list of errors to be able to identify the error code.

What’s new in the ODB1 scanner and ODB2 scanner is that they come in Spanish and are designed to show from error codes to present the error position on the computer screen, the graphics where the fault is presented and what you should do to correct it.

To connect it, the engine must be off and then turn the ignition key to the on position, but do not start the engine. Set the OBD2 scanner to work so that it shows the error codes.

This may vary depending on the model of the scanner.

Access the MENU at the moment the scanner completes its initialization. Select the option of CODES or ERROR CODES and in this way you will open the codes menu.
