DRIVING YOUR LOAD (A, B) CURRENT INTENSITY AND PRESENT IN THIS VOLTAGE are monitored (9A, 9B) by comparison of their HEATS WITH CURRENT THRESHOLD AND A WINDOW OF HEATS ALLOWABLE VOLTAGE. When the voltage is OUT OF SECURITIES ELIGIBLE AND / OR current falls below its threshold an error message (FAULT) and the nature of the fault (short circuit in the NUCLEO, LOAD OPEN, SHORT CIRCUIT IN TENSION NETWORK distribution), IS ALSO IDENTIFIED BY THE ISSUANCE OF A SIGNAL FOR DIAGNOSIS Natico A (Diaga, DIAGB). IDENTIFICATION (STAGE) STAGE OR PHASES OF FAILURE IS ALSO PROVITA IF circuit includes several phases in parallel. INTENDED APPLICATION REFERRED TO DRIVE INJECTION engine internal combustion.
