The present invention relates to an electronic control apparatus, more particularly, to a method of checking a reset function in an electronic control apparatus. The present invention checks whether a sub-controller that monitors a main controller in an electronic control apparatus normally performs the function.
Claims8
An electronic control apparatus for checking a reset function, the electronic control apparatus comprising:
- a main controller that outputs a test failure signal, senses a reset signal output from a sub-controller in response to the test failure signal, and checks a reset function of the sub-controller;
- and
- the sub-controller that senses the test failure signal, outputs the reset signal, and controls the reset signal not to be output to a reset pin of the main controller.
A method for an electronic control apparatus to check a reset function, the method comprising the steps of:
- blocking outputting a reset signal to a reset pin of a main controller from a sub-controller;
- outputting a test failure signal from the main controller to the sub-controller;
- outputting a reset signal from the sub-controller in response to the test failure signal;
- and
- sensing, by the main controller, the reset signal so as to check a reset function of the sub-controller.
