IBS (Intelligent Battery Sensor) Wake-Up

IBS Wake-up
When the key is switched off, before the DME enters sleep mode, the DME informs the IBS of the current SoC (state of charge) of the battery. The IBS monitors the SoC (state of charge) and when it drops below the programmed threshold, a wake-up signal is sent to the DME via the BSD. The DME wakes up, obtains information on the current SoC (state of charge) of the battery from the IBS and requests the auxiliary electrical loads to switch off.
After one wake-up sequence the IBS is prohibited from waking the vehicle again during this key off cycle. The vehicle subsequently reassumes sleep mode.
