If you need to disable your Wabco CMS for any reason, there are a few different ways that you can do so. One way is to simply unplug the device from its power source. This will cause the CMS to cease all operations and will prevent it from being able to turn back on again without being plugged in. Another way to disable your Wabco CMS is to remove the batteries from the device. This will also cause the device to cease all operations and will prevent it from turning back on until new batteries are inserted. Finally, you can also disable your Wabco CMS by pressing and holding the power button for 5 seconds. This will activate a special disable mode which will deactivate all of the sensors and motors inside of the device. The Wabco CMS will then be unable to turn back on until this mode is manually turned off again.
