Meritor Wabco (Wabco)

Meritor Wabco Vehicle Control Systems (Meritor Wabco) is recalling certain trailer spring brake control valves sold as replacement parts with dates codes ending in 0113 through 1113. The affected spring brake control valves (SBCV) have an intake/exhaust valve which may come apart and prevent the parking brake from engaging.

MERITOR WABCO IS RECALLING CERTAIN ELECTRONIC STABILITY CONTROL (ESC) MODULES WITH PART NUMBERS 446 065 020 0, 400 850 179 0, 400 850 195 0, 446 065 027 0, AND 400 850 185 0, SHIPPED TO A VARIETY OF NORTH AMERICAN VEHICLE MANUFACTURERS FROM AUGUST 2005 THROUGH SEPTEMBER 2011. UNDER CERTAIN ROAD AND DRIVING CONDITIONS, VEHICLE BODY ROLL AND ROAD INCLINATION CHARACTERISTICS MAY ADVERSELY AFFECT THE SLIP ANGLE CALCULATION OF THE ELECTRONIC STABILITY CONTROL (ESC) SYSTEM. THIS MIGHT CAUSE THE ESC TO PERCEIVE AN OVER STEERING SITUATION AND THEREFORE APPLY THE OUTER WHEEL BRAKE ON THE FRONT AXLE UNTIL THE VEHICLE IS PERCEIVED TO BE STABLE.
