VEHICLE DESCRIPTION: MOTOR HOMES EQUIPPED WITH MERITOR WABCO PHASE 1, D-VERSION ANTILOCK BRAKE SYSTEM (ABS), FAIL TO COMPLY TO THE REQUIREMENTS OF FMVSS NO. 105, "HYDRAULIC AND ELECTRIC BRAKE SYSTEMS." AN INTERNAL DIAGNOSTIC SYSTEM IN THE ABS MAY NOT DETECT AN EXTREME WHEEL SPEED SENSOR AIR GAP. SUCH A CONDITION COULD POSSIBLY OCCUR DURING (1) ORIGINAL ASSEMBLY OR (2) SUBSEQUENT WHEEL END SERVICE.
THIS COULD DISABLE THE ANTI-LOCK FUNCTION ON THE AFFECTED WHEEL WITHOUT PROVIDING THE REQUIRED OPERATOR WARNING THAT THE ABS FUNCTION REQUIRES SERVICING.
THE ABS ECU WILL BE REMOVED AND REPLACED ON THESE MOTOR HOMES. MERITOR IS CONDUCTING THE OWNER NOTIFICATION AND REMEDY SCHEDULING FOR THIS CAMPAIGN. OWNER NOTIFICATION IS EXPECTED TO BEGIN DURING APRIL/MAY 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT MERITOR WABCO AT 1-800-535-5560.
ALSO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S AUTO SAFETY HOTLINE AT 1-888-DASH-2-DOT (1-888-327-4236).
