Definitions

• the invention relates to an integrated electrical enclosure for a diagnostic port and a low voltage power socket of a vehicle
• Vehicles such as two-wheelers, light-duty cars, trucks etc, generally include on-board diagnostic (OBD) systems provided by respective manufacturers. These diagnostic systems monitor various parameters that affect overall functioning of the vehicle and generate data for further processing.
• OBD on-board diagnostic
• OBD systems feature a network of in-vehicle sensors that monitor the vehicle's electrical, mechanical, and emissions systems, and in response generate data that are processed by the vehicle's control unit.
• the data is used, for example, to detect malfunctions or deterioration in the vehicle's performance.
• the OBD systems include a standardized connector, referred to as an OBD connector’ which provides access to the data processed by the control unit.
• the OBD connector is connected to a part side connector which is further connected to the vehicle wiring system.
• the vehicle wiring system allows data communication from the control unit to the OBD connector.
• a conventional scan tool can be plugged into the OBD connector to retrieve diagnostic data from the vehicle's control unit.
• the OBD connector is typically positioned near an engine of the vehicle. As such, ready accessibility of the OBD connector during a repair process is a persistent concern. Further, replacement and servicing of the OBD connectors requires dis-assembling multiple parts of the vehicle to gain access. Vehicles provided with electronic fuel injection (EFI) system require frequent diagnosis for correction of any faulty codes that may occur. Typically, such data are stored in electronic control unit (ECU) of the vehicle. However, it is not always possible and preferable to access the ECU directly, which makes the positioning of the OBD connector critical in the vehicle layout. Moreover, the positioning of the OBD connector should be such that it should prevent entry of foreign particles like dust, moisture, water and pollutants.
