I completed the mod and it works, but now my ABS light is on all the time...what would have caused this?

1996 4runner limited

Thanks in advance

 

Also, the light was not on before doing the mod. The locker works now in 2 hi 4 hi 4 lo...the ABS light is always on, whether the locker is engaged or not.

 

You clipped and grounded only the wire that leads to the locker module, right? I.e. didn't ground both ends of the clipped wire?

 

Correct,I clipped the red and blue wire, grounded the end that leads to the harness to the side where the other two wires are grounded.the other clipped end was just left hanging

 

Anyone give ANY insight? I just bought this thing, so I don't really have any knowledge...

 

I really can't say. I did this mod on my '99, but didn't have any issues with it afterwards. Check for a blown fuse? Just guessing at this point.

 

I guess I can try hooking it back up to the original wire to see if the light stays on then...

However, before I did this the light was not on, and the problem didn't start until I cut the blue wire with red stripe and connected the tail leading from the harness to ground.

 

I'm a big confused about which side of the cut wire you grounded.

The wiring comes from the dash area to the 4WD control unit in the left kick panel. You ID the correct wire (colors can vary), then cut and ground the wire leading to the control unit, not the one leading back into the dash area. That one you just leave alone.

That circuit grounds when the transfer case goes into low range, which (in addition to making the locker available) disables the ABS. So it's very possible that grounding that side of the wire isn't telling the locker control unit it's OK to go, it's telling the ABS system to disable.

 

I ran a ground wire to the side of the blue/red wire that runs into the harness and plugs into the module.

The locker locks in 2hi, 4hi, and 4lo...but the abs light is always on....

I'm assuming since the locker is actually locking ing different modes that I have it wired correctly...?

 

I'd assume so. As long as the wire that goes the other way back into the dash area isn't grounded in any way.

Again. all I can say is it worked perfectly when I tried it. And as they say, when everything goes well, you don't learn anything new.

 

Sigh...you're right...but wish I didn't have to learn EVERY TIME

 

Ok, another bit of information.

I connected the wire as it was from the factory and the ABS light did not go off.

I also tried putting a jumper between e1 and tc on the under hodd diganose port to see if the ABS light would flash...it didnt, it stayed steady the whole time.

Anyone have any ideas that I could try, or ideas what it might be?

 

is it possible air is in the lines or the pads are worn out? I'm just guessing at this point...

 

find someone to read the code for you. its all random guesses till you know why the light is on.

 

Who would be able to? I have an OBDII reader, but it doesn't access the ABS system...

 

OK, another update, I pulled the short pin out of the diagnosis port and then jumped the tc and e1...I get flash flash flash all at the same interval. Would this be code 30?

 

heres a video:

 

I think that's 33&34, indicating both rear wheels having a speed sensor signal malfunction. Ideas anyone? I was having no problem before the mod, now I can't get the light to go off...(i tried reconnecting the wire as it came from the factory to the harness)

 

Could resetting the ECU(disconnect battery for 5+ mins) fix this?

Anyone chime in...conversation and troubleshooting with myself is getting old...

 

Can ANYONE offer ANY type of assistance? I'm really at a loss...I need SOMETHING to go off of..
