Closed-Circuit Monitoring
Closed-Circuit Monitoring When the vehicle is off the IBS is programmed to wake up every 40 s so that it can update the measured values (Voltage, current, temperature). The measuring time of the IBS is approximately 50 ms.
The DME reads the history of the measurements on start-up. An entry is made in the fault code memory of the DME if a closed-circuit current draw was present.
