ABS and "!" lights are ON again!

I have a service manual on CD, so I found instructions on page AH-14 -- "AXLE – REAR AXLE HUB AND BEARING" and there it provides the instructions:

DISCONNECT SKID CONTROL SENSOR WIRE (w/ABS)
(a) Using a screwdriver, remove the claw of the connector lock portion and disconnect the skid control sensor wire connector.

NOTICE: Do not remove the connector cover from the connector because the skid control sensor wire may be damaged.

I could not remove any "claw" to remove; in fact I don't think there even is one. What I did is I followed CTScott's instruction (I think...) to remove that clip that you can raise up on top of the sensor with a screwdriver. Well, turns out it is sort of a clamshell like cover that surrounds the whole connector. You can see that there is a slotted locking clip that snaps onto a little nub; actually there is one on top and on the bottom. To get the cover off you have to raise both clips and work the thing off.

With the cover off I took a screwdriver and gingerly worked the connector off. It did finally kind of snap off. I did not find any broken pins or anything.

Is that what I was supposed to do, CTScott? When concerns me is that the manual says "Do not remove the connector cover." Well, if by "connector cover" they mean that clamshell thing that surrounds the connector, that ship done sailed. I did not damage the wires, though, and managed to get it back on OK after replaced the connector.

When I had the connector off I checked it for that "claw" they said to remove. I did not find any separate part that I could have removed. That's what confuses me about this whole thing.

They show to release the connector while it is inside of the cover. That may be possible to do if you can get into just the right position, but I find it much easier to remove the cover. As long as you are careful with the cover removal you will not hurt the wire.

So, is that thing they show to pry up in their picture actually a separate piece that you "remove" as they say, or do they mean to just pry it up to release it from a tooth or something? They give you the impression that there is like a clip that you actually pry out and remove. As I said, I looked at the connector carefully and it seemed like it was all one piece to me.

In any case, as you say, it would be pretty tough to get in a position to pry that thing up and pry the connector off at the same time. I agree, it's easier to remove that cover. The wires look delicate, but if you're careful and find any broken I would bet they were already corroded off.

OK, thanks for all your input! (Old subject I know...)

After doing the rear I find that my BRAKE and ABS lights are still on, so I guess I need to check the front now.

Using this procedure you can find out which one is actually causing the error:

You can't replace just the sensors. Only the wires.

[Exiwolfman]

Sensor is I'm the hub unfortunately ull need to replace hub bearing to fix sensor and harness

The hub bearing replacement only fixes the sensor, not the harness.

[limochong]

Yup~ i need to replace both hubs and both wire harnesses.
Can anyone provide me with the costs for parts ?? Thanks

Before selling my Yaris I quoted buying all the necessary parts to fix the ABS / BREAK light issue and the cheapest I could get it was for around $250 but getting some genuine Toyota parts it goes up to around $500

Good luck

Thanks a lot!

Well last cleaned in Nov-2010, the ABS and ((!)) light are on again. Cleaned the connections and the lights are not going out this time.

[Bluevitz-rs]

Connections are probably broken now. You'd have to check with small cheap sowing needles and a DVOM. Digital volt and ohm meter.

Yeah, that'll likely be the next step in the troubleshooting process Hopefully it's the rear harnesses and not the sensors pressed into the hubs...

if u can scan it ...if it shows both sides , take car for spin after code erased when code comes back see if both or just one ..this will eliminate the good one or one that can wait...main problem is that when u get the light ..code.. u have to replace both ( hub ,harness ) cos its the sensor that is 99% gone :( and that will involve a new hub...sorry.

[Exiwolfman]

Yup that is about right ...had a Yaris in with same problem Saturday will need new hub and harness price around 300$

That's a darn Shame. When I bought my 08 new I couldn't find one with the abs or the side airbags either. Now I'm glad I don't have it. Abs is pretty useless anyways..

[craigq]

Replaced the rear passenger side harness (the rubber boot looked terrible, broken up etc.), that didn't clear it. Disconnected the battery cable, not sure if that's required or not as I can't recall what I did the last time, still didn't help. I then replaced the rear hub w/ABS sensor, disconnected negative battery cable, and that cleared it. Wonder when the driver-side will go

Don't have a slide hammer so I improvised a pulley-puller by using two 5" bolts and nuts/washers and some spacers to remove the old hub, surprised it worked
