Abstract: The development in Automobiles had made the Automobile systems more complex. The Automobiles today have many electronic units in it to perform a defined task. Though these units are designed to perform accurately, they eventually develop small faults. These faults are to be recognized quickly for proper functioning of the vehicle. These units should be monitored and check continuously for smooth functioning of the vehicle. This requires a advanced diagnostic technology to detect the fault quickly and intimate them. This paper discusses about advanced method of monitoring the condition of the vehicle and also giving intimation if there occurs any fault in the automobile system. This paper gives the advanced communication between the units which monitor the parameters in the vehicle using the fast and reliable communication technology. This paper proposes a effective communication technology for short range communication like in automobiles. The proposed method can also be easily implemented and is also easily configurable. This method uses a combination of both hardware and software which is easy to implement and is also cost effective.

INTRODUCTION 

         Electronic Control Unit(ECU) a generic term for any embedded system that controls one or more of the electrical systems or subsystems in a motor vehicle. ECU is a combination of both hardware and software called the firmware. The firmware is a combination of Microcontroller hardware and the embedded software. The each ECU in vehicle performs a specific task defined to it. The electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values from a multitude of sensors within the engine. Types of ECU include electronic/engine control module (ECM), transmission control module (TCM), brake control module (BCM), central control module (CCM), central timing module (CTM), general electronic module (GEM), body control module (BCM), suspension control module (SCM), control unit, or control module. Taken together, these systems are sometimes referred to as the car's computer. The earlier systems in the automobiles used analog circuitry to perform the tasks like temperature measurement, level sensing. These analog systems were more bulky and consume more space which became difficult to be used in all vehicles.
