Relay for charge air cooler recirculation pump - task	Actuates the charge air cooler recirculation pump.
Relay for charge air cooler recirculation pump - design	Relay for charge air cooler recirculation pump is a 4-pin plug-in relay.
Relay for charge air cooler recirculation pump, function	On actuation of the ME control unit by a ground signal, the power supply contact closes and thus supplies the charge air cooler recirculation pump (M44) fused with a voltage (circuit 87).
