Thanks, but no specific details mention on the manual to correct "performing self test"
and also tried to upgrade the engine code for "invalid engine code" problem, but no use..
my last option here was to change the board ass'y which will take time coz of parts availability
from local supplier, they have to order this from Dubai supplier also.
