Toyota Auris 1.4 D-4D Bosch EDC17C01 0281015361 1037504207 P673V702 LSU+DPF-off.bin
A catalog guide to the Toyota Auris 1.4 D-4D EDC17C01 firmware labeled LSU+DPF-off, including its diesel engine control role and modified variant.
LSU+DPF-off identifies this catalog file as a modified diesel engine calibration associated with the exhaust oxygen sensor and diesel particulate filter systems. The entry names a Toyota Auris 1.4 D-4D and a Bosch EDC17C01 engine controller, with identifiers 0281015361, 1037504207 and P673V702.
What the engine controller does
The Bosch EDC17C01 is a diesel engine control unit. It manages fuel injection and coordinates engine operation using sensor readings and calibration maps. Its decisions affect starting, power delivery, fuel consumption and exhaust emissions.
In a diesel application equipped with a particulate filter, the controller also monitors conditions relevant to filter loading and regeneration. Regeneration raises exhaust temperature to burn accumulated soot. The exact strategy and equipment present depend on the vehicle and calibration.
What LSU+DPF-off means
The filename Toyota Auris 1.4D4D_Bosch EDC17C01(CP07) 0281015361 1037504207 P673V702 LSU+DPF-off.bin labels this file as an LSU and DPF-off variant, not as a stock calibration. LSU commonly refers to a wideband exhaust oxygen sensor. DPF-off indicates a modification intended to disable some particulate-filter-related software functions. In practice, such changes can affect exhaust monitoring, fault reporting or regeneration behavior, but the filename alone does not establish the exact changes made in this file.
These variant labels apply to this named file. They do not mean that every calibration carrying the same controller or software identifiers has those modifications.
Diagnostic context
A modified calibration can change how the engine controller responds to exhaust-system faults. A missing warning or fault code therefore does not, by itself, confirm that the oxygen sensor or particulate filter is operating correctly. The listed hardware and software numbers help identify the catalog entry, but they are not a guarantee of compatibility with a particular vehicle.
Disabling emissions-control functions can increase pollution and may make a vehicle illegal to use on public roads, depending on local rules.
