Hi guys I have a thread up about my abs
I rectified the open circuit to both RR a RL speed sensor
I hooked it up to techstream cleared code and it stays off then I drive about 20 Meters abs light comes back on
Hook it back up to techstream keeps on coming up rh speed censor circuit with a little frozen sign next to it ,
continuity is good at the ba2 connecter to the back sensor I cleaned and rings as they were dirty
The freeze sign worries me is it stored can I erase it
Always does the same thing goes off and stays off and 20 Meters down the road comes back on
Any help will be greatly appreciated
I know I'm close but not close enough
I know my drum pads are low on the r hand side but surely it's not that there's no sensors or nothing for that and the light comes back on before I even brake

*** Changed rear pads no good

It should give you a diagnostic trouble code (DTC) like C0200/31.

Is it possible I'm getting good continuity whilst stationary even when I spin wheel by hand it's like when I get to about 20 30 K while under way it comes back on
Like start checks fine etc
Should mention it's a new sensor old wire

I'm thinking change wire to ba2 to speed sensor
And only choice after that really is abs module ????

That code is for the rear right wheel speed sensor.

Go to the sensor and inspect it. Make sure its bolted down and seated properly.

Undo the sensor plug and grab a multimeter. Check resistance between the two pins of the sensor and you should get 0.6 to 1.8 kΩ

then test between Pin 1 to ground (chassis) then Pin 2 to ground. You should get 10 kΩ or more for both.

If the sensor is fine then it might be the hub itself. I would still try another sensor first though.
