Defect description
VEHICLE DESCRIPTION: TRAILERS EQUIPPED WITH 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. AN INCORRECTLY INSTALLED SEAL COULD PERMIT WATER TO ENTER THE ECU CAUSING A FAULT TO DEVELOP. THIS WILL CAUSE THE VEHICLE'S TRAILER ABS WARNING LAMP TO ILLUMINATE IMMEDIATELY WHEN THE WATER CONTACTS THE BOARD, DEACTIVATING ALL OR PART OF THE ABS.
Safety risk
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.
