ABS fault

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi Folks,

Can anyone let me know if it's likely for an ABS ECU to 

go faulty on a '00 N15?

It's got an intermittent ABS light coming on when it 

feels like (no pattern to it)

I checked it last week and it gave me fault code 35 left 

rear open circuit but after checking the resistance at 

the ECU it seemed in spec with no change while doing a 

'wiggle' test along the length of the wiring.

I tried to clear the code but to no avail despite the ABS 

light not staying in at the time.

Just checked again tonight and I've still got code 35 but 

now also have 26 and 36 as well left front and left rear 

short circuit!!! Why oh why could/should it have a short 

and open circuit fault on the same circuit!?

Resistance check on left rear still in spec (approx 

1400ohms) but I checked the right rear as well and found 

it still in spec but quite a bit lower (approx 900ohms).

Once again the ECU is not letting me clear the codes 

using the procedure detailed by autodata.

Any thoughts / experience???

Cheers

Kenny

	Hi Kenny. First thing to check on this would be for any damage to the ABS rings on your front CV joints. They are really common for cracking and can cause all sorts of issues. Mick
