What is OBD?
On-Board Diagnostics (OBD) is a term referring to a vehicle’s self-diagnostic and reporting system. Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allows a technician to rapidly identify and remedy malfunctions within the vehicle.
OBD-II was driven by a mandate by the State of California for statewide vehicle emissions testing. The US Federal Government (EPA) soon followed and the OBD-II specification was made mandatory for all cars sold in the United States beginning with the 1996 model year. The OBD electrical connector on all MINIs is located under the dashboard adjacent to the left kick panel.
If your Check Engine Light (CEL) comes on, this indicates the on-board computer(s) has sensed something is wrong or not within the preset normal operating limits. A simple plug-in OBD-II scan tool can read the DTC code(s) which will define the problem sensed by the ECU. Any big box auto parts store will read OBD-II DTC codes as a courtesy service. You can also purchase an inexpensive scan tool or OBD-II Bluetooth reader and connect to a smart phone using an app such as Torque or OBD Check.
P Codes=Powertrain (engine) related issues.
U Codes=Vehicle networking or internal CAN buss communication issues.
