|EXHAUST GAS RECIRCULATION - System Overview|
|The Exhaust Gas Recirculation (EGR) system is based around a small ECU which, using engine demand and temperature, controls a valve that mixes an amount of the engines exhaust gases with the air being drawn into the engine for combustion (recirculation).|

|EXHAUST GAS RECIRCULATION - Known Fitments|
|Vehicle makes, models and variants known or believed to be using this vehicle system, required diagnostic lead and degree of known compatibility.

|Details of the pin usage for the ECU connector(s).
|SM008 - EXHAUST GAS RECIRCULATION - Diagnostic Capabilities (Read Fault Codes)|
|Reads the fault code memory. The ECU can self detect up to 8 different problems with itself, its wiring and its associated sensors, storing the respective code if it detects any malfunction or reading outside of pre defined acceptable limits. Not all stored faults may cause the fault warning lamp to illuminate.|
|SM008 - EXHAUST GAS RECIRCULATION - Diagnostic Capabilities (Clear Fault Codes)|
|The system automatically stops reporting any repaired problems.|
|SM008 - EXHAUST GAS RECIRCULATION - Diagnostic Capabilities (Settings)|
|Values, configuration settings, and other stored information which can be read from the ECU, edited and then rewritten back. Read settings can also be stored as a standard HTML page for reference. These pages can then later be re loaded and re written back to the ECU. Please note that some values may be Read Only due to the fact that they are supplied from the ECUís ROM or are internally calculated.
|SM008 - EXHAUST GAS RECIRCULATION - Diagnostic Capabilities (Inputs)|
|Realtime live display of the information the electronic control unit of the selected vehicle system is currently deriving from it's input sensors.
|SM008 - EXHAUST GAS RECIRCULATION - Diagnostic Capabilities (Other)|
|This function allows the valve (known as the Modulator) which controls the mix, to be driven to any position dictated by the values in the range 0 to 255 to check it's correct operation and that the ECU has full control over the valve.|
