Nissan Pathfinder Check Engine Light Reset Can Be Done With OBD-II Scanner? (2023)

It is not necessary to disconnect the battery to reset the Nissan Pathfinder check engine light. The Nissan Pathfinder check engine light can be reset using a diagnostic scan tool, which is connected to the vehicle’s onboard diagnostic (OBD-II) port. This tool can read and clear the diagnostic trouble codes (DTCs) stored in the vehicle’s computer.

Disconnecting the battery can erase the DTCs, but it will not fix the underlying issue that caused the light to come on in the first place, and it will not give you any information about what caused the Nissan Pathfinder check engine light to turn on, which means that you will not be able to fix the problem. Additionally, disconnecting the battery can also erase other important data such as radio presets, clock settings, and the vehicle’s customization settings.

Once the DTCs are cleared, take the vehicle for a test drive and pay attention to any unusual behavior or performance issues. If the Nissan Pathfinder check engine light comes back on, it’s best to have the vehicle inspected by a professional mechanic as soon as possible to diagnose and fix the underlying issue.

Is There A Specific Button Or Switch To Nissan Pathfinder Check Engine Light Reset On A Vehicle?

In most cases, there is no specific button or switch to Nissan Pathfinder check engine light reset on a vehicle. Instead, the process of clearing DTCs involves accessing the computer system through its programming and diagnostic tools. Most modern vehicles have an onboard diagnostics port (OBD-II) located under the dashboard near the driver’s side knee.

The button or switch to reset the Nissan Pathfinder check engine light is located under the dash, in the area above the steering column. You’ll find a small black box with a red button on it that can be pressed to clear out any DTCs from memory and reset them back to zero.

This port is used to connect the vehicle’s computer to a diagnostic scanner. The scanner can then read and clear Nissan Pathfinder check engine light reset codes as well as display other information about the car’s performance. If the vehicle does not have an OBD-II port, it may still be possible to clear the Nissan Pathfinder check engine light.

The Nissan Pathfinder is one example of a car without an OBD-II port, but still has a way for owners to clear DTCs. The owner’s manual for this model year describes how to use a jumper wire to reset the computer system.

Will Nissan Pathfinder Check Engine Light Reset Erase Any Diagnostic Trouble Codes?

Yes, resetting the Nissan Pathfinder check engine light on a vehicle whether using a diagnostic scan tool or doing the other reset ways will erase any diagnostic trouble codes (DTCs) stored in the vehicle’s computer. Once the DTCs are cleared, the Nissan Pathfinder check engine light will turn off.

However, it’s important to keep in mind that simply clearing the DTCs does not fix the underlying issue that caused the Nissan Pathfinder check engine light to turn on. It’s necessary to diagnose and repair the problem before resetting the Nissan Pathfinder check engine light, or the light will come on again soon after.

It’s also important to note that clearing the DTCs will also clear any pending codes, meaning that codes that had not yet set the Nissan Pathfinder check engine light on, but were stored in the vehicle’s computer will be deleted.

It’s always best to have a professional mechanic diagnose the problem, as they will have the knowledge and experience to properly diagnose the issue and make the necessary repairs to keep your vehicle running properly.
