Defect Summary:
EQUIPMENT DESCRIPTION: ANTILOCK BRAKING SYSTEM (ABS) ELECTRONIC CONTROL UNITS (ECU) FOR OVER-THE-ROAD TRAILER APPLICATIONS. THE COVER SEAL (O-RING) MAY HAVE BEEN IMPROPERLY INSTALLED IN CERTAIN EASY-STOP TRAILER ABS ELECTRONIC CONTROL UNITS.

Consequence Summary:
IF THE WARNING LAMP SIGNAL IS IGNORED FOR A PERIOD OF TIME, CORROSION CAN DEVELOP EVENTUALLY LEAKING TO A COMPLETE LOSS OF ECU FUNCTION. THE SERVICE BRAKES WOULD CONTINUE TO BE FULLY FUNCTIONAL.
