    Outdoor unit does not have timer led.
    Your error code means that indoor unit doesn't receive communication signal from outdoor unit.

    1. Check cabel conection indoor<->outdoor units
    2. Check fuse 20A on outdoor unit

    found out that the fault is the out door board after talking with fujitsu tec dept. IE checked voltage on term 3 on the outdoor board the n tested it on the indoor board, both readings the same. \\\\going to remove the old system and fit a mitsi heavy inverter as i have had no trouble with them. Thanks to all
