504REVO-E Heat pump 5 Troubleshooting5.5 Error codesF01 ECU internal errorSystem behavior– System not functioning & display off (GH) / LED notblinkingor– Display shows 'boot’ and ‘Err code’Necessary inspections– Test system using DCT– Inspect the power supply of the SC620Actions– Replace SC620F02 PWM axial fan defectiveSystem behavior– Refrigerant compressor stops during CoolingMode– Axial fans do not run despite Cooling Mode beingactivated– System in Ventilation Mode despite coolingdemand from vehicle activeNecessary inspections– Inspect axial fans. Use the DCT from the diagnos-tic case.– Inspect cable harnesses according to wiring plan– Force control of system via DCT test mode "Activewith cooling”Actions– Replace SC620– Replacing axial fans NOT necessaryF03 PWM double radial blowers defectiveSystem behavior– Failure of all double radial blowers in system– Refrigerant compressor stops during Cooling Mode– System in Ventilation Mode despite cooling being re-quired in vehicleNecessary inspections– Inspect double radial blowers. Use the DCT from thediagnostic case.– Inspect cable harnesses according to wiring plan– Force control of system via DCT test mode "Activewith cooling”Actions– Replace SC620– Replacing double radial blowers NOT necessaryF04 24V power supply too lowSystem behavior– double radial blowers not functioning– Cooling Mode not functioning– Power supply < 22V/ >10sNecessary inspections– Inspect 24V power supply (error active up to powersupply >28V)Actions– Bus servicing necessaryF05 External temperature signal not received >10sSystem behavior– Limited cooling function– System in Cooling ModeNecessary inspections– Inspect external temperature sensor of bus– Inspect CAN bus communicationActions– according to Volvo documentationF06 600V system status not received >10sSystem behavior– Limited cooling functionality– System in Cooling ModeNecessary inspections– Inspect system with DCT component test– Inspect CAN bus communicationActions– according to Volvo documentationF07 Temperature of air duct / outlet temperature toohigh (T≥ 105°C)System behavior– Limited heating functionalityNecessary inspections– Sensor values using DCT– Sensor resistance on the sensor / to the SC620 plug(SC620 not connected) according to wiring plan10kOhm 12.5kOhm 15.7kOhm25°C 20°C 15°C– Voltage present on sensor when SC620 and sensorplug connected1.36V 1.5V 1.7V25°C 20°C 15°C |
