I replaced the abs module last year cause the car went into limp mode as it wouldn't communicate with the car.
I sent the old one for repair but they said it was totally beyond repair so I chucked used one on the car.
Whoever put the tape on the lights did it over 20 years ago so maybe it is the sensors - they look original as I replaced the two front driveshafts a few months ago too.
I can swap the sensors and if that works all good but my scanner won't be able to turn off the abs light.
