A friends Syncro has this issue & it is controllable in that if you immediately turn the Key to Start

the LowLevelLED will blink NonStop but if you turn the Key to On & wait for 10-15 before Starting then

the LED performs normally ~ Not really sure what it means though ~

                                                                ORR ~ DeanB
