OBD scanner not working in 1 2009 but works in a 2005 and a different 2009.

Hi all,

I bought a blue panlog scanner. It works in my cars (prius 09 and 96 Rav 4) and my friends 05 prius. My friends car is on its last leg . He is looking at a used 09 with 174k on it. The problem is neither of my panalog scanners (2) will not light up. He went down with a 500.00 Scanner. I don't know what brand. I believe that scanner works on his car. It would not recognize the car.
The mechanics 10k scanner works in the car. He is afraid if he buys the car, The state inspection scanner will not read.
any ideas why my scanner won't work when it works in 2 other prii?

The car is at my mechanics. He can be a hot head. It hasn't been used in a little over a year. When I saw it I started it up no problem and saw that there was no rust on it. I told my friend and a few days later he went to look at it. It was obvious the 12v battery need to be changed. It was supposedly changed and I went down took it for a spin around the block. I drove like new. no codes. My friend went down the next day with the scanner. He took it on the highway lights went on and off. it definitely needs 2new tps. He liked the way it drove. The mechanic wasn't there. I went down 2x over the weekend car started no problem and then this am I went down there and car started and was scanned with mechanics scanner.

 

tire pressure sensors

 

I know the battery in that

I doubt this has anything to do with it but I know the battery in the fob is dead. could that be the issue?

My friend is going to buy the car.

 

My friend picked up the car the other day. His mechanic and neighbor is a state inspector. the scanner works but the cars abs light keeps flashing on and off. There are no codes.
