my ABS light is on, car usually starts up and drives for about 10 seconds before it turns on. anybody have any idea how to diagnose it? its a 92 prelude Si. i read in a magazine how to check the code like you would the engine light, but i forgot what it was. thanks guys for any help.

 

Well, I'll throw out the easy fix, as it's about all I have expertise for. I had a problem similar to that, and it was just my brake fluid being low. Put some in and it worked fine.

 

i checked both resovoirs and they seem fine, full to the top. ill check again though, thanks. any other ideas?

 

check the sensors, I had a similar problem that unfortunately lead me to pay for a diagnostic test and was told I had a loose sensor...

 

im checking the sensors now and the fluid levels again, thanks.

anyone else know anything about this?

 

I have a trouble shooting guide for this at home. If I don't answer back by tonight remind me with a PM. It might be late when I post it.

 

The only car I ever had ABS on was my 4 door GSR My ABS light turned on and all it was was one of my tires was Low!!! check your tire pressure..this might not be the problem but it be cool if that's all it was.....it was in my GSR

 

Here comes the worst case scenario game. Why? Because I'm living it right now. ABS light.

I need AT LEAST a modulator and probably a pump. $2k in parts. And damned right I'm going to shell it out (this is without labor btw, that would be another $400).

You Do check the ABS code the exact same way you pull the code for the check engine light. The only difference is that the cel will flash the stored codes until you remove the jumper, the abs will only cycle the codes twice. Pull the abs code and post it up and we can tell you what is malfunctioning. Best case scenario is that a wheel speed sensor is fubared, worst cas is pump motor overrun/modulator malfunction etc. . . those are very pricey to fix.

I took out my abs lightbulb

 

hmm, that sucks, i just had an abs modulator and pump out that i tossed out, you could have had it.

Did you use the prop. valve and master cylinder from a non abs S prelude?

 

yeah, hardlines for the front brakes too

ahh well thats cool

no the cars ABS components are all original, never did anything with them.

is there any chance having two diff kinds of tires would mess with it? i dont know the exact sizes right now, but my rear tires are winter and the front two are regular, front are wider too. the back tires got jacked up so i have the winters on there till i buy new ones. but the ABS light didnt come on till like a month later.
