Is it just a case of disconnecting the battery for a couple of hours yeah? Just wanted to give it a reset. Will it re-learn quite quickly? Run a bit lumpy and idle funny for the first few miles? Cheers. |

the ecu, to an extent, is learnable. also, any previous error codes that the ECU had stored will still be stored even if said error has been fixed. re-setting the ECU just allows a clean slate so to speak. |

I believe pulling the fuse would also work too yes. Providing like you said, you left it out for a while.

reset ecu if... - Check Engine Light(CEL) is up and you've solve the problem - minor mod to the engine, if you still use the standard self-learning ecu purpose... so that the ecu start to read it's default mapping and to receive new feedback from sensors in order to create new 'self-learned' mapping anyway, the ecu will still continue to learn and change the mapping even if you didn't reset it... unless it's due to the CEL then you reset in order to clear the problem code and let the ecu check for further problem if any...

disconnect the battery or pull the efi fuse from the fuse box in the engine bay... sometime you might want to reset if you feel your car is slugish or fuel consumption became higher suddenly...

Hey guys, I heard that you should reset the ECU by disconnecting the battery terminals every time you go for a hard drive, long road trip or after putting in a new modification. Is this true? Cos i've also heard that is is bad to disconnect the battery |

Not after hard driveing anyways. I reckon you only need to do it when you change the octane petrol your using or add a performance mod. |

you don't need to disconnect the battery, you can pull out one of the fuses and it does the same thing, not sure which one though |

Think it's the EFI fuse, there is a legend inside the Fuse box that should indicate which one this is |

There is a little clip on the side of the fuse , use a small flat screw driver to release it and fuse will pull out , had mine out the other day with no problems
