How many times do the lights flash AFTER attempting to remote start?
Module will lose ready mode when:
Hand brake is lost
a door is opened after ready mode is set
hood/trunk is detected open
Without a TEST-ONE , it will be hard to diagnose which status if knocking out the EVO from Ready Mode since it is all on CAN-BUS. Keep in mind, if it was working before, and now it stopped, maybe something is wrong on the car..... bad door pin, bad hood trigger, burnt light in the back.. those can all cause ready mode to be lost. Without proper tools to diagnose the problem, it's a bit hard for anyone to test anything.
