Well, never heard of this code before. Pretty cool feature though, apparently since 2014 or so on Chrysler minivans:
The hinge assembly lifts the rear of the hood to allow the hood to "catch" the pedestrian and absorb some of the impact.
"I have been getting the error "Service Active Hood System" in the EVIC intermittently. I connected an OBDII reader and got the DTC code B22A5-00 for the electronic pedestrian protection module (eppm)."
At this rate seems like they will put an airbag assembly on the front bumper to protect pedestrians. At the local university kids keep not looking up from their phones and get hit by cars. Usually by the mirrors though; thankfully most drivers try very hard to miss them. No fatalities but lots of injuries.
