99 V70R AWD - ABS randomly engages

bearreport · Post by **bearreport** » 08 Jun 2017, 16:49

Hopefully this video helps a little. I drive a 99 V70R AWD. ABS will randomly engage when I'm driving. No particular conditions seem to trigger ABS engaging. I've replace the sensor pair for the rear and the front driver's side module because I was getting codes for faults on those sensors. I've replaced the ABS module with a refurbed unit from Midwest ABS as well. Now I don't have any ABS codes or Brake lights - but the ABS problem persists. Sometimes ABS engages as soon as I brake - some times I can hear it grinding even when I'm not on the brakes at all. I have tried blasting everything to hell with brake cleaner but no luck. Any tips on where to look next would be appreciated.

I wasn't able to open your youtube link.

Do you have VIDA handy?

here's a direct link

Not at the moment - I will download it and check it out. I was previously getting codes for low signal from rear and front driver side sensor, replaced them, and still have the same issue

Are you still getting codes from those sensor locations?

Are all 4 tires at the same tread level and same brand, size, age, installation date?

What's the indicator light that's on in the bottom right?

That's a check engine light for an accelerator position code sensor. No codes from any of the sensor locations. Tires are evenly worn and everything about them is the same.
