Dummys guide to reseting ecu

[chillcupra]

I want to reset my ecu. Is it just a case of removing the negative wire?

Thanks

 

[mattyfab]

Yeah and leave it at least half an hour.

Does this reset the clock or odometer?

 

[mattyfab]

It wont reset the odometer no, but the clock will reset if the battery is off long enough, unless it has a strong capacitor

Does this reset the clock or odometer?

If only!!

 

[EdButler]

it DOES reset the trip Odometers tho - its not a stupid question!!

It will also reset your Radio so make sure you have your radio code etc to hand.

If your wanting to do it with regards to the other ECU reset thread though, i really wouldnt bother. Its not worth the hassle and its hardly as though your ECU is going to 'forget' how to achieve maximum performance, unless you do reset it!

Was going to talk about TB rest but "dirty" desiels don't have then

 

[Aimez]

do a search someone did a good step by step guide of the best way of doing this like warming the car up first then driving it through the gears.

 

[rashcupra]

disconnecting the battery wont get rid of a remap will it surely not!

 

[chillcupra]

Nope It deffo wont

 

[rashcupra]

Im thinking about doing this as my car had 140 miles on it when I got it. I have a plastic tag with the keys with a 2 digit number and a 5 digit number on it, is this the radio code?

 

[rashcupra]

radeo code is a 4 digit number does any1 know how to get it off safe mode?

 

[kriso]

just found the code written in the radio manual

 

[rashcupra]

sorted remember you have to press the PTY button to enter the code not the SCAN button like it says in the manual

 

[kriso]

Says PTY in my manual, looks like they fixed the mistake lol

To get out of safe mode leave for an hour then u can re-enter code

 

[rashcupra]

well it went in safe mode when i left jbs and its in safe mode when i got home 4 hours later!

 

[kriso]

dont u just enter the code if it says SAFE then if u get it wrong it will say 2 SAFE until waiting time is up then it will let u try again. Says one hour waiting time in manual and radio has to be powered on during that time.
