Waveform 8
Vehicle speed signal
WAVEFORM 8 REFERENCE CHART
| ECM Terminal Names | Between SPD and E1 |
| Tester Ranges | 2 V/DIV, 20 msec./DIV |
| Conditions | Driving at 12 mph (20 km/h) |
HINT:
- The wavelength becomes shorter as the vehicle speed increases.
- Depending on the vehicle, the output waveform voltage may rise to 12 V if influenced by optionally installed systems.
