Display Of Freeze Frame Data (OBD Mode)
NOTE:
- For detailed operation procedures, refer to "Application help".
- A list of the support data is shown in the following table.
| Display | Content | Unit of measure |
|---|---|---|
| Freeze frame data | Trouble code when memorizing freeze frame data | - |
| Fuel system for Bank 1 | Feedback status of air fuel ratio for the RH bank. Open: Feedback is stopped Closed: Feedback control is being performed |
- |
| Calculated load value | Current rate of air amount. Value assuming that the air amount at the current engine speed with the throttle fully open is 100%. |
% |
| Coolant Temperature | Value calculated from engine coolant temperature sensor output value. | °C or °F |
| Short term fuel trim B1 | Main correction value of A/F feedback control. (Bank 1) | % |
| Long term fuel trim B1 | Main learning value of A/F feedback control. (Bank 1) | % |
| Intake Manifold Absolute Pressure | Value calculated from the intake manifold pressure sensor. | mmHg, kPa, inHg or psi |
| Engine speed | Calculated from crankshaft position sensor signal. | rpm |
| Vehicle speed | Value calculated from vehicle speed sensor output value. | km/h or MPH |
| Ignition timing adv. #1 | Ignition timing control value for No. 1 cylinder. Calculated from rotation speed, intake manifold pressure, intake air temperature, water temperature, and data from knock sensor etc. |
° |
| Intake Air Temperature | Intake air temperature calculated from the intake air temperature sensor output value. | °C |
| Mass Air Flow | Amount of intake air calculated from air flow sensor output value. | g/s |
| Throttle Opening Angle | Throttle opening angle in percentage. Calculated from throttle position sensor output value. | % |
| Secondary air system | Secondary air control status. | - |
| Oxygen sensor #12 | Rear oxygen sensor voltage value on the RH bank. | V |
| Short term fuel trim #12 | Air fuel ratio correction control value for the RH bank rear side. | % |
| OBD System | Shows the OBD regulation to be followed. This is the information recorded in the ECM, and it does not mean that the unit automatically judges the compliance to the OBD regulations. | - |
| (Oxygen sensor #11) | Shows that the front oxygen sensor for RH bank is installed. | - |
| (Oxygen sensor #12) | Shows that the rear oxygen sensor for RH bank is installed. | - |
| Time Since Engine Start | Elapsed time after starting the engine. | sec |
| Evap Purge | Evaporative purge rate displayed by the OBD. | % |
| Fuel Level | Fuel level sensor output value. ECM input value. Total value of main and sub. |
% |
| Atmospheric pressure | Atmospheric pressure calculated from atmospheric pressure sensor output value. | mmHg, kPa, inHg or psig |
| ECU ACC | ECM input power supply voltage. | V |
| Absolute Load Value | Percentage of current intake air amount against the maximum air intake amount of the engine. For non-turbo engine, the value can be close to 95%, but will never be 100%. For turbo engine, this value may exceed 100% due to a boost pressure. |
% |
| Target Equivalence Ratio | Target air fuel ratio. (Lambda) It usually becomes 1.0 aiming at a theoretical air fuel ratio. |
- |
| Relative Throttle Opening Angle | Current throttle opening angle in percentage against the throttle voltage (full range) that has reflected the full close point learning value. The value will be approx. 70% at full open. |
% |
| Ambient Temperature | Ambient temperature that ECM estimates by input values from the engine coolant temperature sensor or the intake air temperature sensor etc. | °C or °F |
| Absolute Throttle Pos.#2 | Shows the sub throttle sensor voltage value in % against the full-range 5 V throttle sensor output voltage. | % |
| Accelerator Pedal Pos.#1 | Shows the main accelerator sensor voltage value in % against the full-range 5 V. | % |
| Accelerator Pedal Pos.#2 | Shows the sub accelerator sensor voltage value in % against the full-range 5 V. | % |
| Target Throttle Opening Angle | Control value of the target throttle opening angle calculated by ECM. Target value of opening angle in percentage when 0% means fully closed and 100% means fully open. | % |
| MT gear status | Neutral condition. Information input from the neutral switch. (MT model) |
