2000 Concorde ABS issues.

Need some help, I had both of my front wheel hubs replaced yesterday and now after leaving my ABS and Trac light are both lit, this doesnt seem to always happen after stopping and restarting the car, example, I left work and the lights were off, went to brake and it felt like the trac control was taking over without any kind of slipping (no ice or water on the road) then after a few seconds the lights come on and the brakes work fine. Goto advance and had them read the codes and drove home with no lights coming on or brake issues(2 minute drive), im a little perplexed as it was working just fine before this and its throwing several codes now. the fact that neither of my back wheels were touched and they are throwing codes is confusing.
4 - rf wheel speed signal malfunction
6 - lr wheel speed signal malfunction
9 rl wheel speed signal malfunction
10 valve power feed malfunction
and 15 over voltage.

ABS is from what I've found in practice, one of the most sensitive modules to improper battery voltage. Whether it be high or low you likely have an issue with the charging system or battery. Perhaps, just a bad or undercharged battery.

I can't imagine thats the case, my alternator is less than 5 months old, and I had no issues with my ABS until the front wheel hubs were replaced yesterday. Battery should not be an issue aswell as I dont believe it is that old. ;/

Well then, I'd have the work done rechecked to be sure the tone wheels or sensors were not damaged in the process of fixing the hubs.

Look for the Car Maintenance Reminder (or Pro if you have multiple cars -- worth the money!!!) Helps to keep track of ALL maintenance (even what you do yourself)

Hehe, iv got a program like that on my phone.
Is there any way to disable the ABS/ Trac control completely so it stops messing with my brakes when I first start driving? I cant get it back to the mechanic until next week.

Those last two codes appear to be a common thread. I'm guessing if you don't have proper source voltages then the sensors themselves wouldn't work right.

Have you looked closely at the two front wheel sensors? Maybe one has a short in now due the handling for the hub replacements. Maybe disconnect each front ABS sensor one at a time to see if there's any change in codes?

Yeah - I also have to think it's related to the work done in that area. Sensor wire is likely unplugged or damaged. Or else it's a pretty big coinkidink.

There are a couple of ABS fuses that will simply disable the ABS, so your brakes would then just work like a car that does not have ABS (can't say that about '02 and later cars because they delete the proportioning valves on all LH's with ABS starting with '02 - so for '02 and later with the ABS disabled, the brakes would not be balanced - could be dangerous). Sorry I'm not with my FSM's to look up the fuse numbers.


'98 LXi - Later Concorde gages (black w/ chrome rings)/'99 LX - LHS gages (white) - HIR bulbs

I'll have the guy look at thursday, taking it to have my starter replaced. hopefully pulling the fuse will help, until the light comes on the brakes have intermittent issues, its like the traction is kicking on when theres no slippage. im hoping its just a loose connection somewhere.

Just dropped it off, I had Advance test the battery and it tested fine save for showing it needed a charge, likely because it was near drained when I replaced the alternator several months ago, i'm hoping the guy can figure it out.

Well the mechanic looked at it and ran the codes and told me the same thing advance did, the back 2 rear sensors, front right and the valve power feed and over voltage, I find it hard to believe all of this randomly failed at once, is it possible its just electrical?
Also everything works fine, traction control kicks on when the car is slipping on ice until the lights come on.
But with the random braking issues that occur before the lights come on iv had to pull abs relay for now
