I'll send out a couple here:
Engine Coolant Temperature -
REQUEST PID is $05
RESPONSE EXAMPLE: 41 05 55 = 45 Degrees Celsius where $55 = 85-40
EXAMPLE 2: 41 05 00 = -40 Degrees Celsius where $00 = 0-40
Vehicle Speed:
REQUEST PID is $0D
RESPONSE EXAMPLE: 41 0D 35 = 53 KM/H where $35 = 53 (no scaling on this one)
EXAMPLE 2: 41 0D FF = 255 KM/H (slow down)
Hope this helps. You can always find the rest in the J1979 documentation from the SAE website.
Can you please explaine me the is difference between the Metric / english units , how to get the difference .
