Method for inspecting and for maintaining an automotive vehicle

A method for inspecting and maintaining a motor vehicle comprising:

• at least one actuator controlled by at least one electronic computer;
• the electronic computer comprising:
• a memory,
• a microcontroller,
• a power module,
• a first communication and control bus,
• a connector,
• the microcontroller being designed to control the actuator using the power module on the basis of a given strategy;
• supervision means able to be coupled to the connector via a connecting cable so as to logically access the electronic computer,
• the inspection and maintenance method comprising:
• a) coupling the supervision means to the electronic computer by way of the connector,
• b) interrogating the computer using the supervision means and displaying a state of the motor vehicle,
• if an anomaly is present on at least one actuator and is communicated by the electronic computer to the supervision means, then the method further comprises:
• c) identifying a defective actuator,
• d) launching a test campaign comprising:
• 1) reading predefined values corresponding to the defective actuator from the memory,
• 2) applying a control signal with the predefined values read from the memory to the actuator,
• 3) measuring actuation parameters of the actuator f in response to the application of the control signal,
• 4) analyzing the results of the actuation parameters of the actuator,
• e) proposing new parameters for the control signal,
• f) applying the control signal with the new parameters to the actuator, measuring and analyzing the actuation parameters, and
• g) recording the new control parameters now being used in the electronic computer.
