Title
(EN) MICROCONTROLLER WITH A DIAGNOSIS MODULE AND METHOD FOR ACCESSING SAID MODULE OF SAID MICROCONTROLLER
(FR) MICROCONTROLEUR AVEC UN MODULE DE DIAGNOSTIC ET PROCEDE D'ACCES AUDIT MODULE DUDIT MICROCONTROLEUR
Abstract
(EN)
The invention relates to a method for accessing at least one diagnosis module (126) of a microcontroller (104) of a vehicle comprising an internal combustion engine, the microcontroller (104) also comprising an input/output bus (106), an interface module (120) coupled to the input/output bus (106) and a microprocessor (105), said method being characterised in that it comprises the following steps: a) reading of at least one data frame (200), b) reading of an identification code (210), c) reading of reference identification data (131) contained in the memory (124), and d) comparing the reference identification data (131) read with the identification data (212) contained in the data frame (200).
