摘要:
A controller for determining whether a previously-detected vehicle wheel speed sensor malfunction still exists. The controller includes an electronic, non-volatile memory, and an electronic processing unit connected to the electronic, non-volatile memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The malfunction monitoring module monitors the operation of at least one wheel speed sensor and generates a fault signal when the at least one sensor malfunctions. The failure handling module causes drive cycle information and the fault information to be stored in the electronic, non-volatile memory. The signal checking module performs a signal check on information from the at least one wheel speed sensor. A tell-tale indicator is deactivated and/or a vehicle control system resumes normal operation if the wheel speed sensor passes the signal check.
