Hello LOGIC, I just looked up a code A4 for a NRR40 it says COP on the VFC has timed out.
-Check vehicle static straps
-Use D-cat, version 2.8 or above to resolve code
-Vehicle Manager may be bad
Looks like you have to hook up the CAT PC to troubleshoot and reset codes. thats all the information i have sorry
