What's wrong?
The vehicle speed control module on affected 2022-2023 New Flyer XE35, XN40, XN35, XE40, XD35, XD40, XD60, and XN60 buses is an electronic control unit for throttle-related commands. In normal operation, the module receives its assigned address after power-up, reads inputs from the bus systems, and sends the correct output signals so engine speed follows the driver's command.
On these buses, the installed MODULE-CM 3033 software can keep running an address detection routine after the address is assigned. If the addressing resistor fails while that routine is still active, the module enters an error state. In that state, its outputs hold at the last known position, so throttle output can stay commanded when the driver has not asked for it.
There is no warning sign before failure. The first sign for an operator can be an engine high-rpm condition or unintended acceleration during the affected operating condition.
