Volvo All Engines (2017 Emissions) Fault Code: P048011 PID: EMS Fan 1 Control Circuit Circuit descriptionElectronic Viscous Fan: The Electronic Fan Drive contains a solenoid that controls the flow of fluid between reservoirs in the fan drive housing and cover. The Engine Control Module (ECM) provides a (PWM) Pulse Width Modulation signal to the solenoid and controls solenoid operation to optimize fan speed, based on coolant temperature, intake air temperature and A/C load.

Volvo All Engines (2017 Emissions) Fault Code: P048013 PID: EMS Fan 1 Control Circuit Fan clutch, On/off control. An internal spring holds the fan clutch in the engaged position. The Fan Clutch Control Valve is a normally closed circuit solenoid that keeps the Fan Clutch released by overcoming the clutch spring by compressed air until the cooling fan is requested by one of the vehicle systems. When the cooling fan is requested, the control solenoid circuit is commanded open. This removes the air supply to the green hose, allowing the fan clutch to engage. This design ensures that if the...
