COMPONENT PARTS EC-821 < SYSTEM DESCRIPTION > [R9M] C D E F G H I J K L M A EC N P O <Reference data> Exhaust Gas Temperature Sensor 2 INFOID:0000000010935533 Upstream DPF Temperature Sensor is installed DPF (Diesel Particulate Filter). The sensor uses a thermistor <Reference data> Glow Control Unit INFOID:0000000010935534 Glow Control Unit performs PWM (Pulse Width Modulation) communication with ECM. It improves engine Glow Plug INFOID:0000000010935535 The glow plug is located in the cylinder head, in order to stabilize combustion and keep good cold start perfor- Glow Indicator Lamp INFOID:0000000010935536 Glow indicator lamp illuminates when glow system is activated in order to inform it to the driver. Cooling Fan INFOID:0000000010935537 Cooling fan operates at each speed when the current flows in the cooling fan motor as follows. EC-843, "COOLING FAN CONTROL : System Description" for cooling fan operation. Cooling Fan Resistor INFOID:0000000010935538 Cooling Fan Resister is installed to the power circuit of Cooling Fan Motor and switches cooling fan speed Thermoplunger INFOID:0000000010935539 Thermoplunger Unit is installed to the passage of engine coolant and has four thermoplungers. These ther- Thermoplunger Control Unit INFOID:0000000010935540 Thermoplunger Control Unit passes a current to Thermoplungers according to a signal transmitted from ECM.
