ABS fault both right wheels

[Jfml]

Hi All,

Any ideas on this one. Had ABS light come on and VCDS shows short to ground/open circuit on both front right and rear right wheels.

I instantly thought can be failed sensors both exactly the same time and the codes point to wiring.

So I looked at wiring and found they both take different routes apart from the first 10inches into the electric box under the battery.

Tested at plugs for with multimeter and found

Front right. pos has voltage (10.7v). pos also has continuity to chassis! Neg has no continuity to chassis!

Rear right. pos has voltage (10.7v) no continuity to chassis. Neg has continuity to chassis.

I'm worried this is the module at fault. Either that or the fault with wiring must be in the first 10inches of loom out of module (which looks undamaged but not easily accessible). Or it's in two places on different runs to each sensor.

Just wondered if anyone had similar before I waste lots of time

Thanks in advance

What was the voltage at rear right?

What was the voltage at rear right?

Sorry just realised the rest of my post if missing! Just edited it back to what I thought I posted!

Sounds like simple damaged loom but then I can't see it and can conceive it happening in two places at the same time!

Have you checked at the connections under the pass seat?
