Hi guys,

Sorry for the newbie post, but I purchased my S2K second hand. I didn't receive the booklet for the headunit, so I wanted to know if it will ask me for a PIN code if I disconnect the battery.

BTW, mine is a '99 model. Any help would be greatly appreciated!

 

Yes disconnecting the battery will require you to enter the radio code and re-enter any pre-set stations.

The code should be in the owner's manual that you get with the car, afik there is no specific HU booklet. If this fails then you'll need to contact your Honda dealer and they can get it for you somehow.

Are you disconnecting the battery for a reason?

 

speedracr, the radio in the '99 model does NOT have a security code number.....I had the same concerns after i bought mine 2nd. hand.......Took me a few phone calls to Honda dealers till i got the answer (previous owner had already left for his o'seas posting) Amazing how few dealers knew that and could help me...one dealer even suggested charging me $60 to remove the radio to get the serial number and send that to Honda Aust with the VIN number to get it....security code was introduced with the '02 model radio..
Happy motoring

 

Yeah I want to reset the ECU. I've had a browse through the owner's manual, and in the Radio/Headunit section it shows three different types of headunits, and mine is the one that it states doesn't have a PIN code.

It didn't sound right to me however, because even my previous Civic CXi required a PIN...?

Stanley: Nice colour you got there... same as mine Thanks for your advice! Anyone else? It's currently 1-1 so could someone please break the tie?

 

Well thank you sincerely for correcting me Stanley I should have included the "apparently" disclaimer

Does seem very strange though since radio codes have been around longer than the S2000 and are considered the norm these days.

I had a holden apollo as a work car for a while and after being misinformed by holden and wasting a trip to them I was then told by toyota that they wanted me to leave the car there for an hour and charge $60 even though I offered to remove the unit myself:bamghead:

 

speedracr I'd ignore my first post over Stan's but you needn't worry about either. I asked why you were doing it because I had a feeling that you were going to reset the ECU. Disconnecting the battery is unnecessary to reset it you simply need to pull the appropriate fuse for ~15s and then replace it. Check in the owner's manual but I think that the fuse is located around the passenger's footwell. Do a search on resetting the ECU and you'll find some guidance but keep in mind that it'd likely be from USDM owners.

 

Okay, now I'm really going to show my ignorance...why would anyone want to reset the ECU?

Fisty

 

The fuse you need to pull is under the dash on the driver's side (RHD) towards the right hand side.

There are two verticle rows of fuses. The one to pull is in the right column, third slot from top (some slots are empty). There is a little white plastic tool mounted just above the fuses for pulling them.

Keep it out for about 30 secs and then reinsert. Your ECU is reset.

 

The ECU has internal memory which allows it to learn what it needs to do to react to certain conditions that it may encounter such as bad fuel or hot air etc. Resetting the ECU forces it to relearn these reactions and often loses any bad habits. This is why it's a good idea to reset it after making engine mods giving it a chance to learn how to react with the new changes rather than making adjustments based on stored data.

I pulled this image from one of Xviper's threads, he posted that the fuse you want to pull is the one labelled 'back up'

 

Another crappy honda service
to get the code in other model, all you have to do is press (i think) 2 buttons on the radio. Do a search and you will find what they are
