Abstract
A vehicle diagnostics clearing system that detects a clear diagnostic faults flag and clears diagnostic faults from a control module includes a clear diagnostic faults flag monitoring module and a clear diagnostic faults module. The clear diagnostic faults flag monitoring module periodically monitors the clear diagnostic faults flag in the control module. When the clear diagnostic faults flag monitoring module detects that the clear diagnostic faults flag is set, the clear diagnostic faults module clears the diagnostic faults from the control module for a predetermined period.
Claims14
A vehicle diagnostics clearing system, comprising:
- a clear diagnostic faults flag monitoring module that periodically monitors a clear diagnostic faults flag in a control module;
- and
- a clear diagnostic faults module that automatically clears diagnostic faults from the control module for a predetermined period after the clear diagnostic faults flag is set in the control module.
A vehicle diagnostics clearing method, comprising:
- periodically determining if a clear diagnostics faults flag has been set;
- and
- automatically clearing diagnostic faults for a predetermined period after the clear diagnostic faults flag has been set.
A method comprising:
- determining if a clear faults flag is set in an engine control module of a vehicle;
- repeatedly clearing diagnostic faults of the engine control module for a predetermined period after the clear faults flag has been set;
- and
- stopping the clearing diagnostic faults after the predetermined period has elapsed.
