Abs Light Lit Constantly - R33 S2

[Primordial]

Hey, I locked up my brakes in the rain the other night, and ever since, my ABS light stays on constantly

I checked the fuses under the bonnet but they are fine. Is there another fuse that might cause this? If not, does anyone know where I should look to diagnose the issue??

*BUMP*

Anyone?

Could be a number of things, one of the wheel speed sensors or the ABS module itself u cant really tell unless u have somthing so you can read the trouble code that its logged.

You could try disconnecting the battery for a while say 15mins so make sure so it clears the memory. then see if it comes back after you reconnect it. because it might be a history code, its happened once and hasnt happened again but its kept the light on to tell u somthing has happened.

Wild guess and say its used somthing in the module it dosnt ususall use that may have stuffed up but i thought abs modules usually do a self test as u first drive off every time the car is started, could be wrong. id think that if the wheel speed sensor was stuffed it wouldntve stuffed up just because the abs was used because the wheel speed sensors are used all the time.

PS: make sure u have all the radio codes and stuff before u disconnect the battery. if ur unit has one.

Where is the ABS module located. I have an R33 GTR, abs not working on it.

I tried disconnecting battery to reset ecu, but it didnt work unfortunately

I'll have to get it checked out by a brake specialist i guess. I doubt anyone will know how to check the sensors etc.

Unfortunately I dont know where the ABS module is either?

Thanks for your help Viper - Ill post up some results once I get it checked out.

when you open the bonnet, your standing in front of the car, look to the right you wil see at the back of the engine bay on the passenger side a box with metal lines coming out, that is the abs module, if you dont have that then you dont have abs.

I know that part However, my mechanic had a look, and said he couldnt find the error as to why its not working, he said there should be a plug for the module, he couldnt find that.

ABS Module should be in booth of car on shelf to the right of the batt etc.

I have read somewhere that you can do diag from the controler much the same as the ecm with the LED or Chk Eng lamp.

I am having an ABS lamp on now, also from locking my wheels in the loose.

I am about to remove my module to see if the diag can be done. will post the results.

This may be something too simple but you guys should check you have enough brake fluid and no air bubbles. I believe no ABS can come on if you don't have enough brake fluid.

ABS is complex.. if u have a fault code.. dnt just clear it.. take it to nissan and get a check done.. check codes..

so u locked up? maybe ur actuator.. check that u didnt damge ur sensors..? sensors should be in the inside or ur driveshafts on the rear from memory.. best to take to nissan and get an intelligent tester onto it.. check ur whole car over for codes...
