: Clear/reset emission-related diagnostic information.

: How parameters like engine RPM, coolant temperature, and oxygen sensor voltages are scaled and transmitted. eys157.part2.rar

: Request current powertrain diagnostic data (live data stream). : Clear/reset emission-related diagnostic information

The primary goal of Eady 157 is to define the communication protocols and data formats for . It ensures that vehicle manufacturers and aftermarket tool developers use a standardized language to retrieve emissions-related data, diagnostic trouble codes (DTCs), and real-time sensor information. 2. Technical Requirements diagnostic trouble codes (DTCs)

The standard specifies how electronic control units (ECUs) should handle requests from external test equipment. Key technical areas include:

: Request emission-related diagnostic trouble codes (stored DTCs).
