How do I permanently delete engine codes?
A Permanent Diagnostic Trouble Code (DTC) is stored when a DTC is confirmed and the Malfunction Indicator Lamp (MIL) has been illuminated. A Permanent DTC can only then be cleared by the module strategy and cannot be erased by clearing DTCs with a scan tool, a Keep-Alive Memory (KAM) reset, or battery disconnect.
Does disconnecting the battery clear codes?
Leaving the battery disconnected for about 15 minutes will ensure the vehicle systems will completely reset when you reconnect the battery. Disconnecting the battery will clear the error codes and reset the check engine light.
Is it OK to clear engine codes?
If your main reason for buying an inexpensive scanner is to reset the check-engine light, know this: clearing the code and turning the light off doesn’t mean your issue has gone away. Some check-engine light warnings are temporary—like the aforementioned loose fuel-filler cap or a rare engine misfire.
Is clearing codes the same as resetting ECU?
Turning back the screw and erasing the codes is the same resetting the ecu.
What happens if you erase trouble codes?
If the DTC is just deleted, the system may not reset the DTC until a certain distance is travelled. This means the system may not be functioning correctly. Another example would be if parts were removed from a vehicle during the repair process and the DTCs were for loss of communication with those parts.
Will AutoZone reset check engine light?

How long should battery be disconnected to reset ECU?
