Replace the MCU PWB ( PL 13.1).
Refer to Figure 1 and check the wire between the SOS PWB (C) P/J514-2 and the MCU PWB P/J401-B9 for an open circuit.
Check the wires between P/J527 and the MCU PWB P/J401 for an open circuit.
If no problems are found, replace the ROS Assembly ( PL 3.1).
If the problem continues, replace the MCU PWB ( PL 13.1).
