June 12, 2020 NHTSA CAMPAIGN NUMBER: 20V352000
Overvoltage Alternator May Cause Engine Shutdown
If the engine shuts down or loses power while the vehicle is in motion, this may increase the risk of a crash.
NHTSA Campaign Number: 20V352
Manufacturer Motor Coach Industries
Components ELECTRICAL SYSTEM
Potential Number of Units Affected 918
Summary
Motor Coach Industries (MCI) is recalling certain 2018-2020 D4000, D4005, D4500, D4505 and D45CRTLE buses manufactured with electric cooling fans (E-fan) for the radiator and charge air cooler, Borg Warner 55SI model dual alternator configuration (with a sense stud and wire), and Parker Vansco Multiplexing Module (VMM) Multiplex system. A build-up of debris, corrosion, and/or water flow could cause a high resistance path to ground for the sense stud on the back of the alternator and cause the alternator to produce excessive voltage output, which may exceed the threshold limit currently programmed in the VMM and result in a loss of engine power and vehicle shutdown.
Remedy
MCI will notify the affected owners, and dealers will install a new application code in the Parker VMM multiplex modules increasing the overvoltage threshold limit, free of charge. The recall began July 23, 2020. Owners may contact MCI customer service at 1-800-241-2947. MCI’s number for this recall is SB 479.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

1.0 Description
Customer complaint:
Motor Coach Industries (MCI) has become aware that certain J4500 and D-series coaches equipped with electric cooling fans (E-fan) for the radiator and charge air cooler, Borg Warner 55SI model dual alternator configuration (with a sense stud and wire), and Parker Vansco Multiplexing Module (VMM) Multiplex system may experience alternator overcharge, which could result in loss of engine power and vehicle shutdown. A loss of engine power and vehicle shutdown may result in a crash and cause personal injury.
Cause:
A build-up of debris, corrosion, and/or water flow could cause a high resistance path to ground for the sense stud on the back of the alternator, which in turn could cause the alternator to operate in an open field mode. It is then possible for the transient voltage to exceed the overvoltage threshold limit of the multiplex module as it is currently programmed.
Corrective action:
MCI will remedy the affected coaches at no cost to customers by reflashing the Parker multiplex application code. Proper repairs will require the use of specialized equipment, and therefore MCI recommends owners of the affected coaches to make an appointment as soon as possible by calling the MCI Customer Service Line at 1-800-241-2947, to have the repairs performed by trained technicians who have the necessary equipment.
