BQ34Z100-G1: Unable to read any data from the IC

Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: EV2400, BQSTUDIO

In our project we using BQ34Z100-G1 as a gas gauge IC for the battery and have pretty strange effect. I2C communications are working for the write address (0xaa), but always timed out for the read address (0xab). 

Did anybody experience similar issue?

Thanks in advance for the help!
