Good checking for vehicle steering angle sensor |
(57) A controller for determining whether a previously-determined vehicle steering 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 vehicle 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
sensor.
