FREIGHTLINER issued a recall on the MBMC, and MT models

Certain vehicles equipped with Meritor WABCO Phase 1, D-version Antilock Brake System (ABS) fail to comply to the requirements of C.M.V.S.S. 105 - Hydraulic 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. The ABS fault light will not activate and the ABS will not function at this wheel position, increasing the risk of a crash. Correction: Dealers will remove and replace the ABS ECU on buses and multi-passenger vehicles and reprogram the ECU for all others.
