NHTSA Campaign 97E039000

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

Issued by ROCKWELL INTERNATIONAL · Reported Nov 19, 1997 · 18,830 vehicles affected

What's wrong

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. 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.

Consequence

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.

Remedy

DEALERS WILL REPLACE THE ECU ON THESE TRAILERS.
