Abstract
A method for reading the state of a plurality of contact variables (Var-1, Var-i, Var-n) of a motor vehicle by a read module (MOD) including a plurality of read ports (P1, Pi, Pn) connected by an electric circuit to the plurality of contact variables, each read port being configured to read the state of a contact variable, the read module being configured to order periodically the reading of the contact, a period including a read interval (Ton) and a sleep interval (Toff), includes a step of detecting a current (Σi=1nIinj_i) injected via the electric circuit across at least one of the read ports during a sleep interval and a step of adapting the period in which the contact variables are read by the read module, such that the detected current (Σi=1nIinj_i) injected during a sleep interval is consumed by the read module during the consecutive read interval.
