2. MODE $01 (CURRENT POWERTRAIN DIAGNOSTIC DATA)
Refer to data denoting the current operating condition of analog input/output, digital input/output or the pow-
ertrain system.
A list of the support data and PID (Parameter Identification) codes are shown in the following table.
NOTE:
Refer to general scan tool manufacturer’s instruction manual to access generic OBD-II PIDs (MODE $01).
3. MODE $02 (POWERTRAIN FREEZE FRAME DATA)
Refer to data denoting the operating condition when trouble is detected by on-board diagnosis system.
A list of the support data and PID (Parameter Identification) codes are shown in the following table.
NOTE:
Refer to general scan tool manufacturer’s operation manual to access freeze frame data (MODE $02).
