Rotary / Pulse Signal |
||
Engine Speed [rpm] |
Indicates engine RPM via a signal from the crankshaft position sensor. If this signal fails, the camshaft position sensor signal is used. This is a standard value for various controls |
When engine stopped (switch in RUN): 0 is displayed. When engine running: engine speed is displayed. |
Vehicle Speed [km/h] |
Indicates vehicle speed via a signal from the vehicle speed sensor (CAN). |
This is not currently being used. |
Analog Signal |
||
Accelerator Pedal Position [%] |
Indicates accelerator position via the accelerator sensor or CAN signal. One standard value that determines fuel injection quantity |
This is not currently being used. |
Accelerator Pedal Position Sensor 1 Output Voltage [V] |
Indicates accelerator sensor output voltage value (system 1) Used to calculate accelerator position |
This is not currently being used. |
Accelerator Pedal Position Sensor 2 Output Voltage [V] |
