I just got my 89 Legend L coupe and last weekend the ALB light keeps on going on and then off... on then off... what the hell?

The rotors and pads were replaced about 4000kms ago. I don't know if this is related, but I also get this really high pitch sound whenever I accelerate at low speeds, but at high speeds they dissappear?

Any ideas?

Check the pads to ensure they are not rubbing. Or the caliper is pinched. I think you hear it "disappear" at higher speeds is due to the revolutions increase, it is still there just less noticable because it is going fast and not rubbing as"long". Not sure about the light, sorry.

Check brake fluid!!!!

Thanks jrock7791 and tabasco!

And for all those who live in Toronto, I know a wicked mechanic that works for an Acura dealership who'll do work on the side. If you want some work done, just give me shout. Just an FYI.

xtcrush,
after checking your brake fluid level, check your alternator to see if it's charging correctly. Not sure where the ABS computer is located on a coupe, on sedans it's in the trunk against the rear seats driver side. Turn your key to the "on" position and report back # of blinks on the ABS computer if both above checks turn out negative.

ABS codes

Are the codes from the ABS computer the same as for the ECU or could you post the codes for the ABS or a link?

Oh and my ABS light comes on after 5 minutes driving but the pads are all in alignment and quite meaty still, fluid levels good, haven't checked codes yet.
Please help!!
Car got major service ~1000kms ago

shadow,
the ABS computer is seperate from the ECU computer and gives seperate codes. I don't have my helms manual at the office, will try to bring it tomorrow. If not email me and remind me, getting old and forgetful these days.

ABS codes are usually due to a faulty wheel sensor or rarely a fail safe relay. Your pads and disc do not affect the ABS computer in any way.

Sometimes simple answers are the best answers!

I put in more brake fluid and the ALB light turned OFF!!!

It's weird though, I checked the break fluid and it was 3/4 full b4 I put more in... don't get it but it worked!

Thanks guys!

BTW, where is the ABS computer on a 89 L coupe. Does it have a LED like the ECU?
