Hello,
I've searched on here, and haven't seen my same exact circumstances, and the things which solved similar circumstances are not clearing mine up. So I was wondering if you guys might be able to suggest something else or confirm that I have done enough to warrant asking for a replacement ABS Module for the one I replaced the broken original with.
My '04 Accord LX v6 (automatic transmission) is alternating between throwing ABS 84-1 and 51-01. After I replaced the module with a used one from a Salvage yard it was throwing both codes. I found a TSB on here about the ground, and checked it. The bolt was corroded, and barely finger tight (thanks Pac Honda Technician who diagnosed the ABS module was bad originially for not solving that issue) so I replaced it with a new bolt, and made sure the connector was clean and tightened down properly.
Now the ABS light does not come on unless I do the Neutral memorization trick with the jumper between pins 4 & 9 to turn the TCS system lights off. If I do that, once I hit 10mph the ABS light pops on as well, and sets code 51-01. I've driven for 20 minutes with the ABS light not coming on, and no codes but 84-1 if I clear the codes and don't do the neutral memorization step.
Is there somewhere else in the system I should be looking? or is it a matter of a bad ABS module still?
Thanks

 

Well, perhaps never mind.
I decided I would try one last time and disconnect the ABS Module connector and reconnect it (battery disconnected of course). I did that, reset the Neutral memorization, and a ten minute test drive yielded no lights. Everything was working with the ABS and TCS so, I guess it needed to be seated when the ground to body was good. I'll monitor it for a few days and see if it pops back on.
