Error Using E1 to read/write V850E2/Fx4-L

I follow information on Connection documents for E1/E20 and V850 family.

The connection as shown in 2 pictures below.

The problem I have now is I get error message "No response from Target Microcontroller (FLMD)
The MCU is on a board but not my design and it is an ECU.
The board can be self-powered either from the system or external. I am using external 5.0V
Please advise me.
