The MCU and the cluster protect themselves from over-current and high voltage input, and diagnose malfunctions caused by short or open circuit in electric system, and display error codes on the cluster.SECTION 5 MECHATRONICS SYSTEMSECTION 5 MECHATRONICS SYSTEMGROUP 1 OUTLINEGROUP 1 OUTLINENEW CAPO SYSTEMPower mode selection (P, S, E)Work mode selectionUser mode system (U)MCU & cluster protectionOpen-short diagnosis & error code displayMachine error & ECM fault code displayMachine condition monitoringElectric signal monitoringMode selection systemAuto deceleration systemPower boost systemTravel control systemAutomatic warming up systemEngine overheat prevention systemVariable power control systemAnti-restart systemSelf-diagnostic systemMachine monitoring systemOne touch deceleration systemAttachment flow control system1, 2 Speed control systemAuto cruise control systemCreep travel control system 5-2SYSTEM DIAGRAMSYSTEM DIAGRAMMain pumpPilot pumpEngineECMCAN 1MCVRH controlleverLH controlleverOne touchdecel buttonPower maxbuttonHorn buttonOptionbuttonN1pressureN2pressureWorkpressureTravelpressureAttachmentpressureAttachmentconfluxAttachmentsafetyCreep travelPower maxArm regen cutAttachment pilotpressureEPPR VALVEBoom priorityAttachmentMCUP1pressureP2pressureP1 P2P3P3pressureOverloadpressuresensorSL SRSwingpressureAO AIArm in/out & Bucket inpressureBIBoom uppressureBUAccel dial Switch signalWork toolClusterSerial communication(+)Serial communication(-)Pressure signalPressure signalPressure signalDrive signalPressure signalSignalDrive signalNormalCN-16EmergencyCN-16ACN-16BPump powershift EPPRBoom cylinderShuttleblockOption BArm 1Boom 2SwingBucketArm 2Option A &Arm regenBoom 1Option CDozerTravelDozerpressureTravel control valveTransmisasionoil pressureBrake supply valveBrake oilpressureRear view camera4SOLENOID VALVERam lockSwitch signalPressure signalPressure signalAccel dial signalSwitch signalMTCUCAN 2Speed sensorCreep switchRam lock switchTOONOFFSwitch signalPWTSelect switch 2Auto cruiseNFRIIIRH multifunction swAuto cruise switch14W95MS01 . -- -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- 5-2 7Group 13 EPPR Valve -- -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - . -- -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- 5 -1 3Group 11 Self-Diagnostic System -- -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - -- - --
