Abstract
A control system for a vehicle includes a wake-up module and a failure detection module. The wake-up module selectively powers on a vehicle control module, wherein the vehicle control module controls sub-systems of the vehicle. The failure detection module detects a failure of the wake-up module during a period when the vehicle control module is powered off and an enable condition is met, wherein the failure is detected based on (i) whether an internal wake-up is requested or an external wake-up is requested during a first predetermined period and (ii) whether a run/crank (R/C) operation is requested.
