ENGINE (DIAGNOSTICS)
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.
PID
02 DTC that caused CARB required freeze frame data storage
03 Fuel system control status
04 Calculated engine load value
05 Engine coolant temperature
06 Short term fuel trim
07 Long term fuel trim
0B Intake manifold absolute pressure
0C Engine revolution
0D Vehicle speed
0E Ignition timing advance
0F Intake air temperature
10 Air flow rate from mass air flow sensor
11 Throttle valve absolute opening angle
NOTE:
Refer to general scan tool manufacturer's operation manual to access freeze frame data (MODE $02).
4. MODE $03 (EMISSION-RELATED POWERTRAIN DIAGNOSTIC TROUBLE CODE (DTC))
Refer to "List of Diagnostic Trouble Code (DTC)" for information about data denoting emission-related pow-
ertrain DTC. <Ref. to EN(H4DOTC)(diag)-62, List of Diagnostic Trouble Code (DTC).>
5. MODE $04 (CLEAR/RESET EMISSION-RELATED DIAGNOSTIC INFORMATION)
Refer to the mode used to clear or reset emission-related diagnostic information.
NOTE:
Refer to general scan tool manufacturer's operation manual to clear or reset emission-related diagnostic in-
formation (MODE $04).
