What is the difference between the R5B and the R5/FCX 3?
The R5B only resets the service reminder lights known as oil service and inspection lights. The R5/FCX is much more capable. Of course it will reset the oil service and inspection Lights, but its main strength is its ability to read and display all engine codes, and reset the “Check Engine” and “Service Engine Soon” lights.
