Windshield Washer Interferes with ABS
In the development cycle of a certain automobile, it was found that the pump motor for the windshield washer was creating interference and causing an ABS warning light to activate. This vehicle's brake lines were coated with a new material which had a much higher conductivity than on older models. It was later determined that the pump motor was generating a transient that was … [Read more...]
