Went out for the test driving session to check the ABS performance and wheel speed signal quality at higher speed.
Before going onto the main road and while all four tyres are still cold, activated the ABS.
As expected, so much quicker and smoother operation of ABS and of course, no more of that dreadful squeaking noise from the classic ABS pump.
On to the main road and brought the speed up to 70mph to check the noise on the existing wheel speed sensors.
No ABS or TCS lights so happy with the result.
To the owner:
It is mentioned in the installation manual but from now on, if you get ABS warning light, please note that you don’t use the blue 2pin SCS terminal inside the cabin at the passenger foot well area for the diagnosis purpose.
You will still use it for any other warning lights such as CEL, EPS (if you have one), etc but not for the ABS.
The ABS-SCS terminal is now located outside of the cabin and it is mounted nearby the new ABS modulator as in the centre of this photo.
Just remove it from the blanking mating connector and use the paper clip to short the two female terminals. Then, turn the IG key into P2/ON position to read the error code.
In my view, it's much easier than crawling under the passenger foot area trying to find that blue 2pin connector behind the carpet.
Also, everything related to ABS including the 4 x wheel speed signal are packaged in one place under the bonnet so much easier to diagnose any issues.
Unlike the classic ABS, you won’t be able to erase the error code by removing the fuse or the battery.
You must follow the specific sequences described in my ABS Upgrade Loom Installation Manual.
It will involve the usage of the brake pedal, new ABS-SCS terminal and the IG key.
You need to operate them at the specific timing by the status of the ABS light.
In order to confirm the ABS-SCS terminal operation, carried out the error code erase procedure and the ABS light flashed twice at the end of the sequence to confirm that it successfully erased any codes stored (there was none any way).
Normally in Japan, the NSX specialists will just cut off all of the orange connectors and wires neatly that are no longer in use as the owners will never go back to the ancient classic ABS once they have experienced the superior performance of the upgraded ABS.
For now, I’ll just keep them as they are and we can decide what to do later.
I prefer removing the classic ABS pump relay to prevent any short circuit at the large 2pin orange connector.
As always, it’s not new brake pad or disc so adjusted the fluid level to this point and not at the max level.
The classic 1st gen ABS and the controller + 4 x fixing bolt.
Considering the state of the modulator with leaky solenoid(s), they are no use to me.
I already have two other classic ABS modulators in the garage so this one will go into my storage area or I’m more than happy for the owner to take them back with him to save my space.
Done.
Time to work on the door windows…..
