Eady 157 builds upon and references several industry-critical publications, including:

: Standards governing physical layers and connector pins (e.g., J1962). eys157.part2.rar

: International standards for controller area networks (CAN) and unified diagnostic services (UDS). eys157.part2.rar

: Request current powertrain diagnostic data (live data stream). eys157.part2.rar

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

: Specific hex codes (e.g., Mode $01 through Mode $0A) used to trigger different diagnostic functions.

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