abs pump kicking on
 

working on a 2001 xc70. when at a stop sign I turn right and accelerate the abs pump activates for a few seconds and shuts off.It only does it on right turns and from a stop.I have checked both front tone rings and wheel speed sensors and all are ok. Checked the abs module at the connector and no corrosion. Looked at the front wires for wheel speed sensors and they are not rubbing or touching anywhere. It does not kick on the abs light at all and it has no abs codes at all. Has anybody ran into this before?
