The purpose of the test is to determine which one is faulty. If you want to spend money on something that may not be the cause of your problems that is for you to decide.

Wammers I was over-thinking the process I just need to fit a blanking plug in the side of the pump where the banji-screw connects into the pump. I was trying to figure out how to fit a blanking plug into the banji-screw end. Will test soon as I find a blanking plug to fit in the pump.
Thanks-All for advice!!!!!

Wammers is the expert. Anything he says should be top priority.

+1 just do as he says itl work.
Grrrrrrr Thanks! I will this weekend. It just wasn't clicking with me how to perform Wammers instructions. Once I watched a video of someone taking a part an abs unit it started making since. For instance modulator/block are used interchangeably by some. A Blanking plug is generic for plugging an outlet or inlet. All of are very helpful and take time to respond.
I Thank you and will let you know how it goes.

A suitable metal plug and a copper washer will seal for the purpose of the test. If the NRV has failed depressurising will not be a problem. If it has not, cutting a slot in one side of the threads on the plug, will allow pressure to be released progressively by slowly backing the plug off.

I would not mess around with anything to do with brakes. I know of one thread where the guy retrofitted 4W traction control to an earlier model swapping some wires over and shortly after he stopped posting. Draw your own conclusions from that.
Hey Grrrr, not sure I follow. Are you just saying be careful because pressure will build in pump and safety is a concern? I found a tapered-rubber blanking plug to fit in the pump and an extra-fine threaded 10mm 1.00 pitch bolt to screw-in to the pump. Which one do you suggest I use to do Wammers test?

No, I am saying don't mix and match modulators. Keep ABS ECU for 0W TC and modulator together, same with 2W and 4W. The pump, accumulator and switch are the same, iirc. I think the same switch was used by a Saab too.

A rubber plug will not hold the pressure.

+1 on that.
The modulator/block/abs unit has a bar-code with numbers. After "Test" if it needs replacing, what numbers must match
Will use threaded bolt.
Will use threaded bolt.
Thank you!!

Got it! You all are Great!!! Great Forum!
By the way what does the ETC mean? Pretty sure its electronic tracking control. Do the numbers identify which drive system I have (ie.. 2W, 4W ). Not sure what 0WTC means?

Electronic traction control. Yours may have rear TC but it should not have four wheel TC. When the ECU detects a spinning wheel from ABS sensor signal. It applies the brake to that wheel to send drive to the wheel with grip. Four wheel TC came in from 1999.

ANR2239.
Edit: just seen Datatek has already responded!
My memory is a bit hit and miss but I think 2239 is 2W TC.
Thanks Grrrrr! Going to run TEST at half-time.
