The L/H Cover Assembly can beopened/closed.Y NReinstall the L/H Cover Assembly (PL 2.6).Check the installation of the L/H Cover Interlock Switch. The L/H Cover Interlock Switch isinstalled correctly.Y NInstall the L/H Cover Interlock Switch correctly.Execute Component Control [071-300 L/H Cover Interlock Switch]. Open and close the L/HCover Assembly. The display changes.Y NCheck the connections of P/J120 and P/J405. P/J120 and P/J405 are connected cor-rectly.Y NConnect P/J120 and P/J405.Check the wire between J405 and J120 for an open circuit or a short circuit (BSD 1.3 Flag3/Flag 4). The wire between J405 and J120 is conducting without an open circuit ora short circuit.Y NRepair the open circuit or short circuit.Check the conductivity of the L/H Cover Interlock Switch (PL 2.6) between J405-1 andJ405-2 (BSD 1.3 Flag 3/Flag 4). The wire between J405-1 and J405-2 is connectingsuccessfully when the L/H Cover Assembly is closed, and is insulated when thecover is open.Y NReplace the L/H Cover Interlock Switch (PL 2.6).Measure the voltage between the MCU PWB P405-2 (+) and GND (-) (BSD 1.3 Flag 3/Flag 4). The voltage is approx. +24VDC.Y NMeasure the voltage between the MCU PWB P400-1 (+) and GND (-) (BSD 1.2 Flag1). The voltage is approx. +24VDC.Y NCheck the connections of P/J526 and P/J400. P/J526 and P/J400 are con-nected correctly.Y NConnect P/J526 and P/J400.Check the wire between J526 and J400 for an open circuit or a short circuit(BSD 1.2 Flag 1). The wire between J526 and J400 is conducting withoutan open circuit or a short circuit.Y NRepair the open circuit or short circuit.Check the connections of P/J521, P/J523 and P/J300, P/J301. P/J521, P/J523 and P/J300, P/J301 are connected correctly.Y NConnect P/J521, P/J523 and P/J300, P/J301.Check the wire between J521, J523 and J300, J301 for an open circuit or ashort circuit. The wire between J521, J523 and J300, J301 are conductingwithout an open circuit or a short circuit.Y NRepair the open circuit or short circuit.Measure the voltage between the ESS PWB P301-3 (+) and GND (-). Thevoltage is approx. +5VDC.Y NReplace the ESS PWB (PL 9.2).Replace the Power Unit (PL 9.1).Replace the MCU PWB (PL 9.1).Replace the MCU PWB (PL 9.1).Replace the MCU PWB (PL 9.1).AABBCCDD
