Does the car have a round three pin plug made from green plastic?
If so then yes, pscan can access the 5AS, read the EKA and code in replacement fobs.
However it can't (yet) access the Honda engine ECU.
I didn't know that Honda engine ECUs could work with the 5AS, so that will be interesting to confirm.
On the other hand if the alarm is a Honda based system then pscan will not (yet) work with it.
