Hey all, My Car is a 1993 honda Accord with manual transmission. I've had a problem with my ABS functionality for a few years now.My car was falling apart so I slowly started to fix all its problems.CV Axles (for an ABS car), strut replacement, muffler replacement andfinally I got my cruise control working!! Now it's time to tackle myABS. After starting my car the ABS light goes through its normal cyclesand stays off. When I drive for about 30 seconds the light comes onand stays solid, no flashing. Following the manual's ABStroubleshooting section, I believe I am to jumper the SCS to get theDTC to flash on the instrument panel. I unplugged the B2 fusetemporarily to reset the DTC memory thinking it was remembering aprevious code with no luck. First, the only suspect connector I could find only turns on mycheck engine light. I thought these two connectors were one in thesame, but I guess perhaps there is another for the ABS? Going through the manual, some examples are given as to why the ABSlight would come on and their respective codes. E.g. parking brakeengaged for more than 30 seconds, the DTC is 2-1. However, my lightstays solid and I do not know how to get the code from it...any suggestions? thanks,scube

the scs connector is a two pin blue connector under the glovebox.jump it, then turn the key on. I bet you get 1 1- something. the 30sec interval is the key. it's a high pressure failure. now go price anabs pump and prepare for heart failure. Chip

Following the ABS troubleshooting steps; Have any suggestions?

Well, it turns out that engine diagnostic connector is the same as the ABS diagnostic connector. The ABS codes did not report anything wrong w/ the wheel sensors. They did report a pressure issue however. The flow chart in the manual says to bleed the high pressure fluid from the ABS system and measure it's volume. Then, run the pump a bit. There is a T-wrench tool that is used to turn the bleed valve. It is a square headed screw and I was wondering if anyone knows if I can get this valve open w/ out having to buy a $100 wrench. I know it's got a resevoir thing on top to catch the high pressue fluid, but what's wrong w/ a hose plugged over the valve opening and a wrench that is the correct size to turn the valve open. What size is the head of this bleed valve? anyone know for a 1993 honda Accord?

I don't wanna buy a tool I'll use for one job one time..(hopefully..)

thanks all!

aside question, while on the subject of abs brake problems, why will the abs light on a '93 t-c chrysler minivan come on at start up, go off, and in a few secs come

back on again and stay on until the key is turned off.?

This might occur for a 30 day period, then it will work normally for 30 days, and then repeat the "on" thingy again for 30 days, why?

btw - is there an abs light relay, a relay for the abs light - only?

excuse me for butting in, but the abs brake subject is one of interest to me,

since the abs light on a '93 t-c chrysler minivan has a pattern of coming on -

going off and then coming back on, and stays on at start up until the key is turned off.

It'll do this for 30 days, then act normal for thirty days, and then repeat the "on" problem for thirty days. "the timing is an estimate".

I would settle for "pulling" the plug on the abs brake system - if I knew how.

It has had recalls / repairs, but there is a customer charge for - non-warranted issues. gets expensive.

any suggestions / help?

btw - where are *these relays located on a '93 chrysler t-c minivan w/abs braking system?

*6-1 Front fail safe relay *6-4 Rear fail safe relay

also - does the abs light have a relay in it's circuit that can be removed - to "shut" it up?:--)

t i a - for any help on turning the light - off, when it just comes on / stays on - unannounced.

You may find a 12 point socket will fit the screw. Honda seems to be in love with 12-points.

yup. id suggest going to wally world and buying a "drive bit" set... as big a set as you can find, with all the bits. see if anything fits. if so? good! if not?

either way, you can return it :) save that receipt!
