Changing the Speed Source with RCM
If you are having issues with your current speed source, like erratic or inaccurate speed readings, you can change the speed source in the RCM. To change the speed source, tap the Diagnostics button and then tap the System Information tab. Now choose “Speed Source” from the drop-down menu. You may need to scroll through the available options to find it.
Any speed sources detected by the RCM will display on the screen with an assigned number. Use the Speed Source Selection drop-down menu to select the new speed source based on its assigned number.
Now the RCM will use the new speed source you have selected.
