Traction Control(ASR) Need a Ginnie pig

[turbocharged798]

I tried to contact you about it, but have no contact info. I can't even email you as the fourms won't let me see your email.



Anyway, I found an ASR switch for $12 off vortex.

Now it was mentioned that 00 and up that the light in the dash will work right off with no wiring. The reason is because of can-bus. It simply communicates with the cluster via the can-bus. 99.5's do not have can bus so the light does not work, but you can make it work by connecting a wire from the ABS unit to the cluster. Some of you probably already knew that, but I just wanted to make that clear as there seems to be a lot of confusion about it. I know as a fact that the 99.5's do have a light in there. It just doesn't work because it has nothing to complete the circuit.

So, I will need to run a wire from pin 15 in the ABS unit, to pin 14 in green connector behind the cluster. Then I will need to branch off that line and go to pin 5 in the ASR switch. Pin 6 in the switch goes to B+(I will steal that from the defrost switch). Pin 2 goes to ground and pin 1 goes to the dash lights.(again, I will take that off the defrost switch as well.)

Of course, this is all coming from my Bentley so if there is an error in there, this will have an error as well.

If I get time, I will write up a easy to understand 99.5 wiring diagram.

Here's a 99.5 ASR wiring diagram for the switch and light that I put together:

My site is my contact. Sorry.

Also...

Made some progress today.

First my ASR unit arrived and looks like the right one thankfully. Then it was a nice day out so I decided to do some pre-wiring and found out a few things.

Pin 14 in the cluster was connected to ground(brown wire). I removed this wire and ran my own wire from pin 14 to the spot in the dash for the ASR switch. Now the ! icon is lit up all the time so that proves that 99.5's do, in fact, have a light installed. As soon as I connect the wire to ground, the light goes out.

Pin 15 in the ABS unit is non-existent. I will need to add the pin to the connector. If anybody knows what repair wire I need, please let me know as I have no clue.

As soon as I figure out this repair wire thing and my ASR switch comes in, I should be home free in having full ASR in my 99.5.

I think I mentioned all of that a couple pages back

Happy to help keep this very old thread alive!
I have an 01 Jetta manufactured 10/2000 with a MK60. I'll be looking for parts and I'm sure I'll be back with questions. Does 1J0 614 417 D sound about right?
Many thanks to all who over the years have researched this and given inspiration!

Have you physically looked at the pump to make sure you have a mk60 and not a mk20? I could swear the changer over occurred later than your cars build date.

Yes, that's what I thought, too. Many here have said the change was mid-2001 model year. The chart in the Bentley manual I have here says I should have a MK 20. It really is a MK 60. I've had the car since new. Weird.

I'd like to do this before winter. I'll bet it will be fun.

Well, I got my ASR unit installed. The ASR light in the dash works perfect. Comes on during key on power up and goes out with the ABS light.

Now the bad news. The ASR button doesn't do anything. I pounded it 100 times and the ASR light will not come on steady. It lights up when I turn on the dash lights, but won't turn off the ASR. ARRRGGGG!!!!!!!!!!!!!!!!

I have yet to see if the ASR actually works.

 

[NB_TDi]

Try try again I guess. The button only turns off the ASR, EDL cannot be shut off.

Find some loose dirt and punch it, you'll know when it's working.

 

[je]

Mine is the same. I know the ASR works, but the button doesn't even light up.

Maybe if I'll pass by your way end of July, I could ask you in then.

Try what? I am going to double check my wiring tomorrow, but I doubt the problem lies there. Maybe the Bently is wrong?

I am quite aware that it turns off the ASR only. I want to be able to shut it off in case I need to get a good running start to get up my steep hill during the winter.

 

[NB_TDi]

Bently isn't wrong, it's working for a lot of members. Including me.

 

[turbocharged798]

It's fixed! The tap connector I used for key on power behind the defrost switch couldn't cut the think insulation on the wire that I used. Stripped some insulation back and reset it. Works perfect now. Light comes on when you hit the button and goes off when you hit it again.

Now to find a spot to test the ASR/EDL. Hehe.

Thanks for the help guys!

I did a successful ASR upgrade to my Golf MK4 brakes. It has AKL engine (Euro 1.6Ltr), cable trottle and ABS-only MK20 controller (1J0 614 117 C + 1J0 907 379 G).
Now it has ASR MK20 controller (1J0 614 417 A + 1J0 907 379 R) with full functionality- when activated, it operates the brakes and cuts the engine power. I also did the wiring to the cluster and to the ASR button, and they also work as expected.
Now I'm waiting for snow and ice to test and enjoy the mod.

 

[Ralphy]

Now let's see how it will soon be on a B4 Passat TDI...

 

[compu_85]

How does it cut power with the cable throttle?

I don't see this working on a Mk3 generation car because ASR uses the CAN bus. Mk3s don't have CAN.

[Ralphy]

Cable throttle? My B4 TDI is drive by wire, and already has the oem MK20 4 chanel ABS module with 25 pins connector. Power is cut if I press go and brake pedal at the same time. A communication route already exist between ECM and ABS module. Can bus is not only on the last years models? Mk20 ASR systems were found OE on 99-2000 A4 cars. I assume I wont have anything more to add than a dash light and a kill switch, but I may be wrong.

 

[david_594]

Cable throttle?

He was responding to the person above you who said their car had a cable throttle.


Jason, if its a gasser engine it could pull timing as a means to cut power.

 

[Ralphy]

Sorry Compu.
Can someone confirm me that the only function of T32a/14 connection is to illuminate an ASR cluster icon?

 

[Ralphy]

Probably not I imagine. T32a/14 seems to be the only connection between ESR module and ECM for engine power reduction. I will have to find a way to route that signal to the good place in my B4 central electric 2, if it can be done.

 

[david_594]

Probably not I imagine. T32a/14 seems to be the only connection between ESR module and ECM for engine power reduction.

Compu is right. In the MK4 you can swap the pump without any of the additional wiring pictured and the ASR will work fine including engine power reduction(minus the ability to disable it). The wire in that image is just for the indicator lamp in the cluster. Can-bus is whats responsible for engine power reduction.

 

[compu_85]

Yes, on the Mk3 generation ABS there is no communication between the ABS pump and the ECU. The ABS harness in those cars is very very simple. I have one on the shelf, I should snap a picture of it.

-J

 

[Ralphy]

Thanks for your input. My ABS module has the 25 pins harness though.

 

[compu_85]

Ya, and I bet the CAN wires are unused I'll have to find that harness, apart from the wires going to the rear wheel speed sensors there's only like 4 wires going into the fuse block!

-J

 

[turbocharged798]

99.5's don't have can-bus and the ASR works just fine.

 

[compu_85]

Yes, 99.5s DO have can bus.....

 

[david_594]

99.5's just lack the K-line => can-bus interface right?

 

[compu_85]

Yup. No CAN gateway in the instrument cluster, although in my car at least the CAN wires do run up to the cluster. The CCM might get it's dashboard illumination over CAN, I haven't checked the wiring diagrams.

 

[je]

The fix to your ASR light is somewhere in this thread already, but you'll have to poke around for it.
