    Hi @Aalekh ,

    Welcome to ST Community!

    The embedded self-test functions allow checking the device functionality without moving it. When the self-test is enabled, an actuation force is applied to the sensor, simulating a definite input acceleration. 

    The completed procedure is described in the section 8 of AN5444:

    Hi @Aalekh ,

    It means that the self test failed.

    Can you share the output values with and without self-test enabled? Which FS did you set? Please note that the values we give are for 2g.
