ABS Module not responding E53.

[Pilko]

Evening all,

Had the trifecta of lights appear intermittently as well as speedo not working, now on permanently. Read that it could be wheel speed sensor on rear left, so on my break at work I swapped the rears to see if its a sensors problem.

Got the software to read the faults however and have the message "no abs module". Time to send module for repair ?

 

Thanks 🙂

Morning Shaun

Not an uncommon problem ECU Testing in Nottingham and BBA Reman in Kent have been fixing these for years 

Good Luck

Had the module sent away for testing and came back with no problems. Connected it and now it actually sees the module.

Replaced both rear wheel speed sensors but still have these 2 faults that won't clear.

Hi Shaun

Try some electrical contact cleaner at the sensor connectors see if that helps

Good Luck

Thanks for the the reply !

But still no luck. The sensors still magneitze and plug in all the way. So could it be both are not sending the signal (wiring damaged further up?)

What does it mean by edges? Detection on the abs ring or just a bad description?

Bit of a pain to strip down but worth checking the ABS ring is not damaged or just simply clogged with mud rust or other ^rap
