hi all, im new here.

i going to tell the history of my pump and i hope some one can help me what's my problem (sorry my english isn't good! ).

i buy honda accord 97lx, when i see the abs pump, this pump leaking fluid from the top and botton (i think) and making a noise intermitent (bbbbrrrrrrrrrrrr stop, brrrrrrrrrrrrrrrr stop, brrrrrrrrrrrr stop, bbbbbbbbbbbbbrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr stop) when i put fluid the buzzing noise was low.

well some friends told me change the pump, i buy another abs pump unit second (new is very expensive) and the mechanical changed, bleed all brake wheels following the sequence, but the new second abs pump when i start up the abs pump make buzzing noise for few minutes them the buzzing noise stop and the abs light is turn on.

i don't know if the same abs pump unit need bleed or what because this unit and before, have dongle to bleed fluid.

i hope some one can tell me what's it...

thank all and have a nice day!!!

 

The abs light coming on means a code was stored. Short the blue 2-pin connector under the glove box and count the abs light flashes.

See: http://www.dhost.info/accordinfo/howto/cel.html

The procedure is identical, except you count the abs light.

An abs code have two parts, a main code and sub code. There is a 1 second pause between the main and sub code, and a 5 second pause for the next code. If there is only one code it will repeat.

So 3 flashes, 1 sec pause, 2 flashes would be a code 3-2.

Post the code on here.

 

hey thanks for the tips.. ok, i follow the steps and i receive this code of the abs light

abs light: 1 flash, after 5 seconds 1 flash, after 5 seconds 1 flash, and thats all finish the flashing in the abs light.

curiously the D4 flash 4 times, them 4 times, them 4 times like a loop.

well i hope this information can help me what's the problem with my car!.

thank friend.!

and have a nice weekend.

 

That is a code 1, abs pump over run.

Check to see if the reservoir is low on fluid (I had this happen on my accord about 5 years ago, never lost fluid to have this happen).

There are other items that can cause this to happen, but start with the simple stuff first.

The D4 light is a problem with the vehicle speed sensor (VSS). Did your check engine light flash a code 17?

 

reservoir of the same abs pump?

woow speed sensor, i replaced this item because the original was broke (old). i buy new speed sensor in ebay last month ago.

well when i make the test the engine light just turn on and never flashed.

thanks for your help.

 

well, i check the reservoir of the abs pump and the fluid is over the maximum limit, maybe this's the problem.

well here the pic for confirm that's the problem.

thanks for your help.

 

That VSS code 4 may be an old code that was never erased. If you remove the radio/backup fuse, maybe this code will go away.

As for the ABS, there is a diagnostic procedure for code 1 in the 94 shop manual that you can download from the links posted in the online manuals thread in the DIY section.

 

hi there, i'm having this problem with my '95 Accord EX. intermittently, the pump will buzz or whine when i start the car. at the same time the noise stops, i'm hearing a 'click' in my dash. i'm guessing that's a relay that's turning the light on. i found a ABS relay in the engine compartment on the right/passenger side. i'm going to look into any leaks, bleeding the system and the o-rings and get back with my results.

thanks fellas!
