• Qualified technicians will begin by using a scan tool to access U1252 code stored in the ECU.

The first step is introductory and is about reacquiring all the canons that have been set. For this, the individual scanner will have to be plugged into the individual harborage of your vehicle. Make sure you indurate frame the data. Any canons that were set previous to the U1252 code will have to be sorted first, as they may have been the reason for the law to set in the first place.

In order to do this, a command can be transferred to the system with scanner or by driving the vehicle under the special conditions that will spark the system. While this is passing keep an eye on the checkup tool data for the result.
