ABS warning lights up

[RTCS]

After starting the engine, all instrumental lights go off as usual. Last few days, after driving for a while the ABS lights up and stays on until turn off engine.

May I know if anyone had this before and what was your remedy? Thanks.

could be a faulty ABS module.

I had this once, and it ended up as only a little short on brake fluid. So check your brake fluid first - cheapest option

Oh, sure hope is this shortage of brake fluid. I will check it out tomorrow morning. Thanks.

could be a faulty ABS module.

ABS module refers to the electrical circuit and not the main pump right? May I know where is the module located, feel like taking it out to take a look. Is it anywhere near the main pump in the bonnet or behind the glove(drawer) or below the steering wheel? Thanks.

Brake fluid. Check the brake fluid.

Re: ABS warning lights up

checked the brake fluid and it is sufficient.

found the abs module which is behind the glove compartment. removed and stripped it. removed the pcb and did some cleaning with wd40 and toothbrush and followed by visual inspection and seems alright. fixed back everything and had high expectation but abs warning light still comes up. wasted 2 1/2 hr.

most likely is the abs pump ko liao, i am hestitating to strip the pump.

My colleague had the same problem and the mechanic who did not want to fleece her checked the electrical connection and the ABS light when off. Subsequently, I told her to change the brake fluid. So far so good!

can try opening up your hood, look for the right side...there's this box with all those little chips in it.....look on the cover for the one controlling the ABS, take the chip out and try putting in another one with same color and voltage (there should be some spares on the underside of the cover)

if your car is no longer under pml warranty, i recommend signing up with Warrantysg | Kar Engineering at least you save $$$ when the ecu or abs breaks down.

That's the fuse right? Unluckily, I've measured the they are not blown. I've even stripped the 2 relays and checked.

Brother, mine is a '92 car wor, don't think got such good lobangs right?

I've also checked the brake fluid as mentioned by MapleLeaf and Joe, still same problem.
