Replacing Front Wheel RDC Sensor

[Grumpy Goat]

This statement is true. You can manually enter a valid sensor ID.

You'll need to wake up the sensor to know it's ID unless you have it documented somewhere.

The instructions from Hexcode are pretty good and they show how to manually enter the sensor ID that is typically included in a label on the sensor. Even some of the aftermarket (Chinese?) sensors have the sensor ID on a label, although the pictures of some of those sensors show no label so a wake-up tool may be needed. I see that Hexcode even suggests another way to wake up the installed new sensor as:

THE CORRECT ALTERNATIVE, also known as the "ALERT method" is to let the air out of the wheel rapidly (we simply depress the valve for around 10 seconds)... this rapid fall in pressure wakes the sensor and places it in an Alert mode, where it starts sending its data (which obviously includes its Sensor ID!).

So it looks like one could even do this without a wake up tool ... again I have not done this myself.
