Description
There is a high voltage wiring system, including the high voltage battery, in the electric powertrain. The high voltage wiring system is insulated from the body on both positive and negative circuits. The leak sensor stops measuring the short circuit resistance when it receives prohibit drive signal from the battery condition monitor module, and sends it signal via the serial communication to the battery condition monitor module. When the battery condition monitor module sends a to drive signal (drive inhibition signal line: high), the leak sensor sends drive stop signal for a set time, the battery condition monitor module detects a malfunction and stores a DTC.
