Ive got the ABS light on all the time, cannot hear abs pump working at any stage and no error code comes up. can anyone help. thanks
Its a 91 auto, the abs pump has never worked since ive had it, discovered after pulling out instrument cluster that the light bulb for alb was missing, so when i replaced it the light is always on!! i have not noticed any leaked fluid.
OK, GOOD. Now we have a starting point. More than likely your ABS system has the systemic problem of a leaky solenoid in the modulator. (The part located directly under the ABS reservoir. I (and most other NSX owners) have been having pretty good luck with flushing and cycling the ABS system to correct the problem. This will be the first step. Where do you live?
How mechanical are you? Go to http://www.danoland.com/nsxgarage then go down the list to ABS, print out the instructions and read it a couple times. He did a good job. No need for me to reiterate what he has done. I have made some additional tools that really help in keeping the air out of the system. After you read the DIY let me know if you think that you could do the procedure. Then we will take it to the next step, OK.

Got a question on the solenoid plugs. Do you push down or lift up the tab on the orange solenoid plugs to separate them? I tried both way but it wouldn't come off. Didn't want pull too hard until I know the proper procedures.
Thanks...:wink:
The solenoid connectors join with the chassis wiring harness connectors and then attach to the hangar bracket. First, remove the orange connectors from the hangar bracket by pushing the orange tab TOWARD the wires in the connector. This tab has a slot in the center of it that has a small curve. Take a look. Push the tab and gently lift/push the connector UP and off of the bracket. Start with the one on the LEFT as looking from the front of the car. Remove all four pair of connectors.
Next, you find the tab on the opposite side and other end of the connector. This tab is in the center of the end of the connector. It has small ripples in the tab. Push the two connector parts like you are pushing them together, then push the tab and the connectors should pull apart. By pushing them together is allows the lock to release easier.
Don't worry about keeping them identified they will only go back together one way. I hope this is understandable. Let me know if not.

Interesting....
Is the Solenoid flush recommended as routine maintenance or should it be left alone as it may break something else in the process?
you need the abs unit flushed and "exercised", as it never gets used and gets gummy if not used and the pistons stick and then the unit will pump all the fluid out on the ground. Acura does not do the repair, they will only replace the unit for about $5k. There is a special tool required to get the unit apart. Go to a third party NSX repair shop and they will do it. Autowave in Huntington Beach CA will do it, as will others.Ive got the ABS light on all the time, cannot hear abs pump working at any stage and no error code comes up. can anyone help. thanks
Thanks Brad...
Does the solenoid flush have the same effect as exercising the ABS on wet pavement? If so, then I guess the solenoid flush is safe to perform. :smile:
I guess I will have to run the pump to build up the pressure for each of the 4 solenoids before the flush?
BTW, what is the yellow wire on the solenoid plug is for?
Thanks ...:wink:
problem fixed!!
it ended up being a faulty connection in the wiring.
