Thank you for the info, I will replace tone ring and check each wheel speed sensor and reinstall abs fuse and report back.

Nobody? Ok how bout the TL;DR...
Speedo shows 30 when gps says 60, tach works fine, down on power til I hit a bump or rough road then speedo jumps back to correct display and power is back. ABS fuse is out because of tone ring problem. Any clues?

Another thing to note, if speedo is working correctly a right turn will send it back to displaying about half true speed but a left turn will have no effect.

2000 V70XC, about 240,000 miles. Not sure because of the issues I’m having. So I have searched and seen most issues are from the ABS module being funky and the speedo and odo drop out completely. Well I have pulled the ABS fuse because I have a broken tone ring on the DS front half shaft. Well mine ...
