Code P1000 KIA Description

The P1000 code for KIA vehicles indicates that the system diagnosis is incomplete. This means that the vehicle's onboard diagnostic system has not completed all of its self-tests. When a vehicle is started, the onboard diagnostic system performs a series of checks to ensure that all components are functioning properly. If the system does not complete these checks, it can indicate a potential issue with the vehicle's systems.

Tech Notes for P1000 KIA

This code just means that the Powertrain Control Module (PCM) didn't complete a full diagnosis cycle, and is set when the battery has been disconnected, codes have been cleared, or sometimes even when the vehicle has been towed. No scanner is necessary to clear the code, driving the vehicle for a few minutes (sometimes more) to complete the diagnosis cycle will clear the code. Clearing the code will reset the light unless other codes are present.
