A diagnostic system for a vehicle includes a comparison module, a disabling module, and a fault indication module. The comparison module indicates whether a temperature of engine coolant is less than a first predetermined temperature. The disabling module disables the comparison module until the temperature of the engine coolant is greater than a second predetermined temperature. The fault indication module diagnoses a fault in response to the comparison module indicating that the temperature of the engine coolant is less than the first predetermined temperature.

Low coolant temperature fault diagnostic systems and methods

A system comprises an electronic device including at least one input for receiving at least one enable signal and external data. The system also comprises a wake-up circuit including at least one input for receiving at least one informational signal, an output for sending the at least one enable signal to the electronic device, and a data interface for external configuration of the wake-up circuit. If the at least one informational signal satisfies predefined criteria, the wake-up circuit enables the electronic device by way of the at least one enable signal before the external data is received by the electronic device.
