7. ABS

I can’t remember how many times I used this ABS T-wrench by now…

For some reason, this service is not included in the Honda’s service schedule and thus, lots of NSX are running with partially serviced ABS.

This one was the same. The fluid inside the reservoir was replaced in the past but the accumulator was not flushed at all. Thus, full of air.

First, I’ll flush the accu. twice.
Then, move onto each solenoid. When you activate the solenoid, it will show lots of tiny bubbles - almost like white fluid.

I don’t like to re-use this so I’ll suck it out and then pour new fluid before activating the pump to pressurise the system and then move onto the next solenoid.


After all four solenoids were flushed, I’ll flush the accumulator again twice. By this time, the fluid retuned to the ABS T-wrench will be clear with no air.
The ABS system has finally serviced properly and should be fine for long period.

It is also important to activate the ABS from time to time to keep the system healthy.


Ultimately, it is best to upgrade to the latest ABS system.
Probably, one of the best modifications that you can do on early models.
