Allow ICMP to DMZ

Question

Hello,
Need some help to allow ICMP from the internet into our internal DMZ.
We have a ASA 5505 with IOS 8.4 with three networks configured. Inside interface 192.168.1.x, outside interface 98.101.206.x, DMZ interface 172.16.5.x we need anyone from the outside or internet to have the ability to ping the DMZ and the servers we have.
We need to know is this possible, if so can you show how to setup the ACL's to allow this.
Thank you

I will try to summit everything you need from the running-config
object network obj_any
subnet 0.0.0.0 0.0.0.0
object network obj-172.16.5.2
host 172.16.5.2
object service FTPS
service tcp source eq 990 destination eq 989

I hope this is all you need, if not please let me know
