4.5 ACTIVE WAKE-UP CAPABILITY
4.5.1 Description
BCM shall get wakeup by the below mentioned wakeup inputs signals (Inputs and Outputs section). BCM
shall wakeup other ECU's with a hardwired wakeup signals based on the wake-up functional requirements.
BCM shall not be required to wake-up other ECUs or woken up by other ECUs on CAN. Only hardwired
wake up and LIN BUS wakeup shall be required.
BCM shall get woken up with any of the below mentioned signal inputs:
Drive Door State
Co-Driver Door State
Other Door State signal
Rear RH door signal
Rear LH door signal
Tail gate signal
Bonnet signal
Driver Door Lock Signal
Driver Door Unlock Signal
Infotainment removal detection
Brake switch signal
Ignition KeyIN signal
Position lamp switch signal
Low Beam Switch Signal
Main Beam Switch Signal
Ignition key IGN signal
Hazard switch signal
Head lamp ON switch signal
Ignition ACC signal
Remote key signals (RF)
LIN bus signals (if any)
BCM Power Reset
4.5.2 Conditional Requirements
BCM shall make hardware wakeup signal output ON and send the corresponding CAN and/or LIN signals
when any of the wake-up input is received.
If BCM detects the new wake-up input then it should activate the wake-up signal output again.
Wake-up output signal pulse ON time (T ON) shall be 100 mSec.
