Q: Hello. Today i buy R270+ black box and everything is ok. I put 35080vp and erase and my tool erase ok i choose program and device say wait 1-3 minutes and in adapter eeprom red led is not working and i wait 10-20 min and light not go on. Can anybody tell how to repair this adapter or my tool is broken?

A:

R270 supports the M35080 series of quick clear, read and write (35080/35080-V6/35080-VP/D80 D0WQ/D160/35160, etc.). Therefore, if you fail to use R270 to work with M35080 eeprom, firstly you have to remove M35080 chip and then plug it into the IC socket, this IC socket is designed for M35080 eeprom. Beside, you need to check if it is well-welded with the board? If not well-welded, it means poor communication, then it can’t quick clear and read the mileage data.
