^^ you try inserting a paper clip into the connector where the caps fluid sensor plugs into? Either that or use an ohm meter to check the caps continuity.
EDIT: This is a non-ABS car (not XLE)
Also this is pretty darn funny: from the service manual page 83 BR.PDF
4. PERFORM TEST DRIVE
(a) Drive for at least 20 seconds at 30 Km/h
(119 mph).
{{ Which one should you believe???? Km/h or mph?
(b) The ABS warning light may not light.
If the ABS warning light lights, read the diagnostic
trouble code.
