| Display | Contents | Remarks |
|---|---|---|
| Engine Speed | Calculated from crankshaft position sensor signal. | rpm |
| Mass Air Flow | Amount of intake air calculated from air flow sensor output value. | g/s or lb/m |
| Vehicle Speed | Value calculated from vehicle speed sensor output value. | km/h or MPH |
| Throttle Opening Angle | Throttle valve opening angle (in percentage) calculated from throttle position sensor output value. | % |
| Ignition Timing Advance for #1 Cylinder | 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. |
° |
| Engine Coolant Temperature | Value calculated from engine coolant temperature sensor output value. | °C or °F |
| Short Term Fuel Trim-Bank1 | Air fuel ratio correction control value for the front. | % |
| Long Term Fuel Trim-Bank1 | Air fuel ratio learning control value for the front. | % |
| Intake Manifold Absolute Pressure | Value calculated from the intake manifold pressure sensor. | kPa, mmHg, inHg or psig |
| Oxygen sensor #12 | Rear oxygen sensor output voltage. | V |
| ECU ACC | ECM input power supply voltage. | V |
| Target Equivalence Ratio | Target air fuel ratio. (Lambda) It usually becomes 1.0 aiming at a theoretical air fuel ratio. |
- |
| Intake Air Temperature | Intake air temperature calculated from the intake air temperature sensor output value. | °C or °F |
| 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 |
| Ambient Temperature Sensor Signal | Data value of the ambient sensor input from the combination meter via CAN. Ambient temperature used for diagnosis. |
°C or °F |
| 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%. |
% |
| 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. |
% |
| Atmospheric Pressure | Atmospheric pressure calculated from atmospheric pressure sensor output value. | kPa, mmHg, inHg or psig |
| Actual Throttle Opening Angle | Actual throttle opening angle. Calculated by ECM based on the throttle sensor input value. |
deg |
| Target Throttle Opening Angle | Control value of the target throttle opening angle calculated by ECM. Shows the target value of opening angle in percentage when 0% means fully closed and 100% means fully open. |
% |
| Relative Throttle Position | 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. |
% |
| Fuel Level | Fuel level sensor output value. ECM input value. Total value of main and sub. |
% |
| Commanded Evap Purge | Evaporative purge rate displayed by the OBD. | % |
| Fuel system for Bank 1 | Feedback status of air fuel ratio. Open: Feedback is stopped Closed: Feedback control is being performed |
- |
| Commanded EGR | Target value as EGR setting value calculated by ECM. | % |
| EGR Error | Percentage of the difference in actual EGR steps as compared to the target EGR steps. Both a positive value and a negative value mean that it doesn't fulfill the target. When the value is positive, it opens more than the target value. When the value is negative, it opens smaller than the target value. |
% |
| Ignition SW ON Count | Time stamp information. Number of times the ignition is ON since the vehicle was manufactured. The number of ignition ON is also recorded when a trouble code is recorded, so the comparison with that number will show you how many times the ignition has turned on since the diagnostic code was recorded. |
times |
| Count | Time stamp information. Each unit individually counts the elapsed time since the ignition is turned ON. Master integrated unit and ECM synchronize with the master time. When synchronized: "Common" When not synchronized: "Originally" |
- |
| Time Count | Time stamp information. Elapsed time after ignition ON. When a trouble code is recorded, the elapsed time after ignition ON is also recorded. |
ms |
| Time Since Engine Start | Elapsed time after starting the engine. | sec |
| AT drive status | Neutral condition. Information input from the inhibitor switch. (CVT model) |
- |
| MT gear status | Neutral condition. Information input from the neutral switch. (MT model) |
- |
| Clutch switch | Clutch switch signal. Set to "ON" when the clutch switch is ON. (MT model) Input value to ECM. |
- |
| O2 Sensor #11 | Installation status of the front oxygen sensor. | - |
| O2 Sensor #12 | Installation status of the rear oxygen sensor. | - |
| Short term fuel trim #12 | Air fuel ratio correction control value for the rear. | % |
| 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. | % |
| 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. |
