00+ ABS Modulator Serial Numbers Database

[vf2ss]

Good question, not all Nissin ABS units say NK8, for ex. a 98-01 Integra ABS modulator and a 2002 TL ABS modulator both say NISSIN NK1, and a 200 series S2K late model AP1 says NISSIN NK11. And while some Nissin units may appear very similar externally, based on what MotorMouth posted earlier are going to be internally programmed differently and not possible to change/tune due to being read-protected.

Highly unlikely. Any company with competent engineers isn't going to leave IP like that exposed regardless of who is "supposed" to have access to it. If it's tunable, there would be a small region of memory where the tuning parameters are stored separate from the actual programming that uses them.

Thanks for your response.

The S2000 didn't come with TCS (became opt. '06, std. in '08) and programmable Hondata Traction Control modules had been developed for '00-'05 S2000 owners (ex. link below).

For NSX owners wanting to upgrade their ABS but their only option is an S2000 unit (not asking for myself, I already upgraded), does anyone know if an S2K ABS unit paired with one of these control modules would be compatibele with an NSX for those owners wanting to keep traction control capability?

Hondata Traction Control

Traction Control for your s300, KPro or FlashPro. Hondata Traction Control works by monitoring the ABS wheel speed sensors and reducing engine output when excessive wheel-spin is detected. A dash mountable switch allows the selection of different target slip rates, and software allows the...

This listing just popped up for a used "Honda NSX late model ABS module 57110-SL0-Z03" on Yahoo Japan Auctions and is currently at $75 USD. 57110-SL0-Z03 in the title which is the correct part number for a late model NSX ABS unit. The description (translated) says "This is an ABS for the NSX. Removed from an early model NA1-100,xxx. There were no problems. A conversion harness will also be included."

A couple red flags though, Part#57110-SL0-Z03 will only appear on the box and NOT on the unit itself. Since this is pulled from a car there is no box obviously to confirm it so the seller is just referencing it. The sticker on the unit itself should say 57105SL0 010 but the pics in the listing don't show that side of the housing to confirm. Also, if you look closely at the third photo the serial starts with a "D" which so far in the database has consistently been a S2000 unit; and if the sticker's still on the housing, my guess it will say 57105S2A J50. I suspect once installed on an NSX with the included conversion harness it'll work but you won't have TCS since I think it's an S2000 unit.

Update: I reached out to the seller to request a pic of the sticker on the black housing but they never got back to me. The used harness included in the listing has me now thinking they upgraded to the S2K unit and then got their hands on a late model OEM ABS unit and was selling their initial upgrade.

@vf2ss Thank you for this thread. Super helpful.

If anyone decides to part with their 2000+ NSX Modulator, please let me know.

@markieb, there was a brand new NSX modulator posted for sale on Facebook a few days ago by @Track Addict so you might message him about it.

Hello NSX fam,

Yeah, I messed up and bought one from Yahoo auctions with a serial number beginning with "B"... not sure what it goes to but the seller marketed it as a ABS modulator for NSX with deleted TCS...

The serial number in the picture begins with "L" but that's not the one I received...

Actual etched serial number is:

B 9K21-0368 B01

Can you tell me if this will fit, @vf2ss?

Please let me know if there's way to identify what the modulator I have goes to or if it's compatible with the NSX. I bought the modulator waaaay before you posted the database.

Thank you so much.

Hi Eric, I am very familiar with that seller and have actually corresponded with him on various listings on different platforms and been following him for over a year watching him sell on average 2-4 used units per month. In the beginning, by titling his listings as being for NSX and labeling them ("with deleted TCS" or "TCS which has poor control has been removed") they were selling upwards of $600-$700USD per unit. Over time the local buying community seemed to figure out they were probably S2000 ABS units and the price has gone down to $200 - $300 USD per unit and has remained that way to present day (example here). There was also a rumor that these units were from retired Honda Racing Teams where they are required to damage or disable a feature on the units before putting them up for sale like removing the TCS, but based on Motormouths earlier comments this seems pretty unlikely.

The seller you bought from maintains a 99.9% reputation with 750 transactions at Yahoo Japan Auctions (after all he did state there would be no TCS and Japanese used parts are usually in stellar condition due to their strict automotive laws for road worthiness). Looking at the Yahoo listing link you provided it appears to have the req'd 8 tiny holes surrounding the polished cylinder and the partially recessed nipple tip on the end which is consistent with an NSX or S2K unit.
Ex. of the 8 holes/dimples...

Ex. of S2000 ABS unit...

For the sake of comparison, the '05-'06 RSX NISSIN NK8 ABS unit of similar shape only has 4 holes around the cylinder and the nipple tip is fully protruded.
Ex. of RSX unit...

I have yet to see a "B" serial like the one you bought but at this point I suspect your "B" serial is from a S2000 based on your pics and would be consistent with what he's been selling all along (remember his high rating) which will be compatible with your NSX; but as stated in the listing you will have no TCS.

It will work great with a T3TEC harness [LINK] (about $260 USD) and since you got the ABS for $250, after it's all said and done you could upgrade your ABS brake system for around $1000 if you do the work yourself [LINK], or closer to $2000-$2500 total if you have someone do the install [ $250 (ABS) + $260 (harness) + $500 (pipes/brackets/bolts/washers/etc. which are readily available parts in the US [LIST HERE]) + $1000-$1500 install (about 8-10 hrs). Note: again, you will need to unplug the wire harness out of the TCS control unit behind the driver seat because the unit will NOT be receiving signals/data from each wheel sensor which will result in codes/cels being thrown. But once unplugged it will work in basically what would be constant "TCS OFF" mode.

Hi vf2ss.

Thank you for the clarification. I thought I was SOL and had to buy another modulator. This thread is very helpful. Thanks again!
