Nowadays a vehicle consists of many Electronic control units which controls electronic components, actuators etc. These electronic control units interact with each other engine related information such as engine speed, engine coolant temperature, engine torque, key status, environmental pressure, environmental temperature etc. these information will be needed by various components for their functioning. This paper describes about one of such application Glow Control Unit (GCU) which makes use of this information on vehicle bus and functions independent of assistance from electronic control unit, GCU is an embedded system which controls the glow plugs which are used to heat the air inside combustion chamber prior to ignition in cold environments. In this project GCU is made up of RL78 microcontroller which provides a cost effective and efficient solution as compared to existing systems.
