The internal watchdog is a separate hardware circuit which continuously monitors the microprocessor. To make sure the controller is operating properly, the watchdog must receive a signal from the microprocessor within a specific time window. After 10 seconds of vehicle operation and noted controller fault identification the transmission will be placed in limp-in and the MIL will illuminate.
