So i just got some bad news! not happy at all!!!!
the Psm/Abs light has been coming on and off for a few weeks, after trying everything, - Broken wires, Sensor, Connections. The final conclusion is the PSM module has gone.....

So what do i do? Used if they are around at all?? New and from who? Any help guys would be greatly appreciated!!!

Statman knows best.

 

How pricey? Where is it located on the car?

 

Cory, Are you sure? I went through this two weeks ago. I was getting ABS/PSM failures all the time even when the car was just idling. I wrote about this exact issue. Since I did all the things in that thread, I have not seen a single fault. I changed nothing.

How do you know the module is toast?

Hey Ben well they did the 10 step procedure that was told to them to do, the messured all the ohms in the wires and they checked out fine. So the last thing was the pump...

What did you end up doing that solved it?

 

Morning Cory,

I cleaned all the ABS sensors, cleaned my MAF wiring harness as it was corroded at both ends. Cleaned the connector at the shock mount, both the brake and ABS connection points.

Disconnected the battery for 20 minutes. Since then not a single fault and I have driven her hard for 500+K. My Durametric said I had a bad brake pedal switch but my brake lights were coming on fine.

Ben

 

i can give it a go. Do you do it yourself?
Where are the ABS Sensors located?

 

Cory,

Don't buy anything yet. Yes I did the work myself as I do a better job than any Porsche shop!!!!

Take the wheels off and look in behind the rotor, you will see a connector with two wires going into it. One is the brake sensor wear wire, the other is the ABS wire going down to the hall effect sensor. You will need a hex set to get the sensor out. Once you unscrew the hex bolt, wiggle the sensor out.

There is a metal clip that hold the connectors in place by the shock tower, you will see it. If you have never cleaned these sensors, they will be filthy dirty. Use brake clean to clean them up.

Don't forget to disconnect the battery to clear the DME and PSM modules.

Let me know what you find..take pics

Ben

 

OK I will give it a shot!

 

Hi Palette,
I am dealing with a similar issue. Have eliminated the actual ABS sensors as the cause and now need to dig a little deeper. Curious to know if the ABS/PSM harness needs to be removed from the vehicle for testing or if it can be trouble shot in place?

Best,
