Honda Mk3 Keyless entry No lights, Will not start, Remote will not open doors.

[Heinrichz]

Hello fellow Fit / Jazz MK3 members
After 2 days of searching for I solution to my problem, I finally solved it.
After disconnecting the battery to install a new radio the following symptoms surfaced after reconnection:-
•   Keyless FOB would not lock/unlock the doors
•   Manually locking the doors from the driver’s position works, but not the back door will lock or unlock
•   Lights not working
•   Radio dead
•   Car does not start
•   Green light flashing on the Start/ Stop button at the top part
•   NOTE:- The hazards do work.
SOLUTION:
Hold the FOB against the start/stop button and press the start / stop button. Does it start /stop
Open the fuse box in the engine bay (passenger side) and look for fuse (# 21? blue) Back Up Main 15 A. It is probably blown. As an emergency, I replaced it with the daytime running lights 15 A fuse as I had none of the mini fuses.
Note my Fit is an RHD Japanese import, so the numbers might not match.
