Please give me the SOTIF improvement requirement by using STPA according to the following sentences: "When the ego vehicle is going to crash against the vehicle in the intersection and ADCU requested deceleration, EBCM didn't respond to execute braking because of no communication setup between ADCU  and EBCM, resulting in the ego vehicle keeping going and collision with the vehicle. " Give two different versions of responses. Please separate the responses with 6 asterisk symbols: ******.
