Engine speed (RPM)

The engine control module (ECM) transmits the engine speed (RPM) on the Control area network (CAN) from which the gearbox control module (TCM) retrieves the signal which it then compares with its own speed sensor signal. The signal is used when shifting and when diagnosing the gearbox speed sensor.

Measurement range: 0 - 8191 RPM
