Stray voltage induced on the power takeoff (pto) signal circuit 510 may occur when the electronic control module (ecm) connector gets wet, causing unintended engine acceleration.

The risk

Unintended engine acceleration while the bus IS in gearmay result in a loss of vehicle control and an accident.
