Does this read issues with hybrid car batteries? Specifically for a GMC Yukon Hybrid 2008?

AD20 Pro bluetooth scanner can retrieve fault codes saved in the battery ECU of a GMC Yukon Hybrid 2008, but it won't provide a detailed code source or possible causes for system-wide fault codes.

Why it asks for the location permission?

The location permission is essential for the proper functioning of the AD20 Pro check engine code reader. The application solely utilizes this permission to calculate the overall distance, record speed of your trips, without accessing or tracking specific locations. Your privacy and data security are our priorities. For any further inquiries, please don't hesitate to contact us at xtoolofficial@gmail.com.

Can it check transmission fluid temperature?

No it can't read transmission fluid temperature, however, it can read basic live data under OBDII section which is related to emission.
