Powering of ADIS16364 inertial sensor under vibration

We are using ADIS16364 in one of our products. We noticed that if the device is powered-up under vibrations it is showing self-test error - DIAG_STAT register is returning readings like 0xE420, 0xEC20, etc. The vibration profile is according to MIL-STD-810G method 514.7 category 13 (L0=0.1g^2/Hz, f0=51Hz).

As it is mentioned in the datasheet reading of this register is also clearing error flags and they doesn't appear any more as long as the device is not restarted.

Our question is if such situation could have any negative effect on the sensor performance during operation. Are there any possible pitfalls in ignoring of self-test error flags in DIAG_STAT register at power-up (i.e. could this mask any potential fault)?
