Abs Light

[heartbrkr]

Hi All,

I had my battery replaced on Wednesday. Took it to an auto electrician, coz originally was going to get some bigger leads put on. However, he had a battery with small terminals which fitted standard leads.

Later that day, I noticed that the ABS light on the dash stays on. Asked my mechanic about it, he told me to leave it a few days to see if it corrects itself. lol.

Anyway, I only have a service manual for s14/200sx, which I was hoping i could use to trouble shoot. In the book it talks about flashing codes on the ABS ecu in the boot. I started following the instructions, but I have an R33, and only thing the boot is a fuse box and what i believe is the Hicas controller.

Problem for me is that there are no lights on the unit, which according to 200sx manual reveal what the problem is.

The auto elec was mucking about wiht the fuse box next to the battery when putting the leads on the battery. I have checked to make sure they are all secure, and nothing apparently lose.

Dont have any other lighs come up on the dash, such as hicas. wondering where to look next. Does anyone have any suggestions. I dont believe it is a fault wiht a sensor (too much coincidence), suspect something near the battery gone bad.

There is a fuse up the front for ABS, which i wasnt able to pull wiht my fingers in the dark. The fuse box in the boot only has a fuse for 4wd/somehting, which i believe is for hicas box. Does the Hicas manage abs, or its there another box i need to find.

Okies.

Checked both 30a fuses under bonnet. Checked every fuse in boot, all good.

Checked Consult docs, nothing about abs faults. Out of ideas. Am I boned?

Hi,

Mate, check your abs relays (in a little black box attached to the ABS motor?).

My ABS light came up after i taped up my coils. I took my car to an autoelectrician who wasted my money (didnt know shit and told me what i had told him when i dropped the car in).

But do take the car to an autoelectrican and test to see if the relay's are working.

If they aren't you need to get new ones. i got my from RS components but an auto-electrician might be able to get them for you. They're about $10 each (there are two relays).

Hope this helps.

Try erasing the code first and see if it comes back

give erasing the code a go and if dont work then try what i've said.

Also, determine when the light is popping up. eg. is it showing up as soon as the motor is started or is only when you start to move.

If is as soon as you start the car, there is a very good chance it is the relays. If it is only when you move, then it could be sensors.
