The inspection and maintenance method including: a) coupling the supervision computer, b) interrogating the electronic computer, if an anomaly is present on at least one actuator, then the method includes: c) identifying the defective actuator, d) launching a test campaign involving: 1) reading predefined values, 2) applying a control signal to the actuator, 3) measuring actuation parameters of the actuator, 4) analyzing the results, e) proposing new parameters, f) applying the control signal with the new parameters, and g) recording the new parameters in the electronic computer.

Abstract: A method for testing, in situ and in operation, a reset device for resetting a computer, including an execution sequence and a verification sequence, the execution sequence being executed during the running of the piece of software and including the following steps: incrementing a test counter, storing the test counter in a non-volatile memory, triggering a reset of the computer, the verification sequence being executed when starting the piece of software and including the following steps: reading the test counter from the non-volatile memory, comparing the test counter: if it is equal to its initial value increased by 1, resetting the test counter, and the test result is positive; and if it is greater than its initial value increased by 1, the test result is negative.

Abstract: The present invention relates to a method for analysing the operation of an anti-pollution system for a motor vehicle (1) with an internal combustion engine, said vehicle (1) comprising at least one sensor for measuring (110) a parameter of the vehicle (1) and an analysis computation means (140) directly connected to said measuring sensor (110), said analysis computation means (140) comprising a memory area, said method being characterised in that it comprises a step for using the measuring sensor (110) to measure at least one parameter of the vehicle (1), a step for using the measuring sensor (110) to transmit at least one digital datum representative of the measured value of the parameter to the analysis computation means (140) and a step for using the analysis computation means (140) to compare said digital datum with a predetermined range of values representative of an operation of the anti-pollution system according to a predetermined standard.
