Traction Control from 2k1 RT and works on the SRT swa! WTF?!

Well..

We got a major dumpin of snow last night. I decided to see how much power I can put down at the wheels while it's spining. I rev it up and my traction light in my ODO flashes and the car slows down..

So, it's confirmed. There is traction control module inside the SRT pcm!

Now I gotta break out the wiring 2k1 RT wiring diagram and find the damn wire and simply disconnect if from the bus system.

car: 2001 RT w/ 100% SRT swap w/ the exception of the dash harness and cluster and interior.

if somebody could guide me where i could do that on the harness.. i'd be more than happy to do that right now!

The low speed traction control system is built into the Teves Mk 20e ABS module, not the PCM. When wheelspin is detected below 35 mph, the Antilock Brake Module (ABM) manipulates the ABS inlet and outlet valves and runs the ABS pump in order to apply the appropriate brake(s) to limit wheelspin. Torque is thereby transferred to the drive wheel with greater traction.

Did you install the SRT-4 ABM (the black box on the ABS unit that says "Teves" or "ATE" on it) when you did your swap, or keep the 2001 R/T ABM?

no..

I have the SRT ABS module complete. I'll have a look inside the hood.. when it's warmer out

The only "traction control" wire is the one leading to the "trac off" switch in the dash. Everything else is done internally by the ABM. When the "trac" indicator flashes, do you hear the ABS pump running and the ABS solenoids making a snapping sound?

Are you sure that you got an SRT-4 ABS assembly? The 2003-07 PT Cruiser turbo has traction control in the ABS, but the SRT-4 ABM never had that feature.

This is pretty interesting b/c I've spun through quite a few times and have never seen my light flash on like it does on the black car

that's bc you're using a SRT cluster, not a RT cluster like I am using.

ACRman, I will get my bro in law to get in the car w/ me to see if he hears the pumping. I cant really hear too well since Im somewhat hard of hearing

I will keep everybody posted.

if you cant find the wire to disconnect or cut in half to stop a signal from turning the traction control on then just replace the dash harness with the srt one and im sure it will go away. tons more work though than just disconnecting a wire :\

That won't work. The traction control is automatically enabled in the ABM at each key-on. It's an ABM software feature. You have to punch the "trac off" button to disable it if you want traction control off. Replacing the dash harness will not disable traction control.

well..

couldnt get my bro in law to come out.. but i tried to go out on my own last night. i couldnt hear anything.. that's prolly bc I cant hear SHIT!

I'm not sure if it is functional, but there is definitely a spot on the SRT cluster that says "TRAC". It's immediately to the right of the DOOR light above the odo.

so i got a question about this actually, you know how the 01 R/T's have a trac off button, if you do the srt motor swap in the r/t but leave the r/t abs module, could you use you traction control as we do now, i mean as in use the button to turn off traction when we want to and leave it on when we need????

refect · Post by **refect** » Thu Apr 05, 2007 12:16 am

if it seems to be working still after the swap then i dont see why the on/off button wouldnt work still either. then again i am not familiar with this happening, and this is actually the first time i have ever heard of it happeneing. so i am not 100% sure on my statement......i still see no reaon why it wouldnt work thoguh if the traction control seems to work. unless wires were switched around a little with the srt and it just casues it to stay on all the time, and the on/off doesnt have any effect....

Well I do still have the ACR Cluster and the trac light does blink when the wheels spin, although I am not sure if the traction actually works. I do not feel a hint that the car is controlling the traction. The light blinks and the wheels spin through the end of second gear that’s all I know. Also I do not have a connection for the trac on/off switch in the bezel, so I guess I have the SRT Interior wiring.

The Trac control works

it's been confirmed. I was on the dyno on saturday and the dyno operator couldnt make power bc the trac control was slowing the car down a LOT by applying the brakes from the ABS.

I simply pulled the ABS fuse in the underhood PDC and voila.. trac control off for the dyno.

The trac control is a PART of the cluster. I have a 03 R/T cluster on the floor in the basement. Im going to get the milage programmed in to match my current milage and will take it back to the dyno to see what will happen from there.

Basically.. 2001 - 2002 RT / ACR cluster or any neons w/ trac control built into the cluster WILL have trac control. You need to pull the fuse out of the PDC - the ABS fuse to turn off the trac control.

I wont go that route bc I use the ABS in my car and plus i hate having a cluster that lights up like a christmas tree! haha
