SB 479 – Overvoltage Alternator May Cause Engine Shutdown – 2018-2020 MCI D4000, D4005, D4500, D4505 & D45CRTLE Buses

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 IndustrieseBay logo

Components ELECTRICAL SYSTEM

Potential Number of Units Affected 918

 

Summary

Motor Coach IndustrieseBay logo (MCIeBay logo) 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

MCIeBay logo 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 MCIeBay logo customer service at 1-800-241-2947. MCIeBay logo’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 IndustrieseBay logo (MCIeBay logo) 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:

MCIeBay logo 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 MCIeBay logo recommends owners of the affected coaches to make an appointment as soon as possible by calling the MCIeBay logo Customer Service Line at 1-800-241-2947, to have the repairs performed by trained technicians who have the necessary equipment.
