Hi Marty Have you worked on WABCO D ecu's

I think it’s in the settings set up, there are many options, I show just a few. They are for something. I leave it on normal until I know what is what!

Good morning Grrrrrr I can’t find Marty?

I want to disconnect the battery and gently clean all connectors on the BECM, I have a small copper wire brush and contact cleaner. The white calc residue that forms on old connectors needs to be removed me thinks?

I Key in, turn to light up dash then ABS failure and Traction failure messages, windows not set, sunroof not set... So, the windows, sunroof etc are physically closed but the BECM is not getting that input as well!

For the purpose of this diagnosis which of the settings should I try to discover the ABS-TC fault? NORMAL ADRE.APP ALM.APP APPMAM.APPAS10.APP BECM.APP CANDET.APP CANINST.APP ETC.....

No, they do sit in a copper mesh bush. The rubber just sits on top but hasn't stop the sensor bedding down. In all this searching for the cause of the ABS-TC dash lights being constantly on I want to try and understand the systems that could lead to this happening: The readout from the dash...

I found another reading regarding brakes Low high brakes at rest High low pedal depressed The WABCO D brake readings ars still close/close-open/open!

Nanocom EDC, WABCO Pics of ABS sensors. Gently tapped in and seated with a copper mallet. The connections have been cleaned and where they should be.

here’s a thing. This truck is on springs! Could that trigger the ABS/TC dash lights? It’s in the WABCO D section on my nanocom?

yes, I thought as much, do these switches fail often, I have tried everything but the result is always both closed or open!

The chances of have the same fault in two switches are slim to FA. I’ve had the nanocom about a week and have been messing with it. Could I have messed up a setting to give a wrong result?

I fitted the new brake switch as per RAVE Readings are: Close/Close Close/Open Open/Open I must be missing something here? ABS/TC dash lights still on. Did I fit the bulb correctly🤔 The dash lights only came on after I fitted new ABS sensors, brake calipers, ball joints, dust shields, and track...

When I remove the switch the Nanocom reads sw 1 closed sw 2 open. When depressing the plunger I can feel it switching halfway and again fully depressed. When I reattach the switch the reading is both closed when depressed, the brake switch was toast, felt like it was full off grit! Replacement...

Very helpful, tomorrow mornings job, by the way nanocom is running as it should, Hope for clear sky's tomorrow, metaphorically as well as weather-wise!

But how do I change the setting for brake switch 2?

Yes, thanks, I am on that now!

I will by some prayer beads!
