Stand alone OBDII scanner as you might expect. Purchased to provide raw data over the processed data driven by many Android apps.
What I like:
1) Easy to use
2) Alternatively battery powered so it can be operated independent of host power
3) Customizable data capture
4) In depth instructions available for download
5) Extensive DTC reading and provides helpful guidance on correcting errors
6) Provides "most" of the data I'm looking for . . .
What I don't like:
1) It's only software compatible with Microsoft, which singularly excludes me.
2) What disappoints me the most is it doesn't provide transmission fluid temperature. It has the capacity to, should a vehicle provide it, I'm suspecting one of two things; a) the 2005 RAV4 has a separate TCM, which I don't believe to be the case, or b) the ECM doesn't read the fluid by mechanism of temperature, but instead just monitors for an open or short in the circuit, indifferent to everything in between. I know for instance the A/T OIL TEMP light will illuminate if the sensor indicated temperature is <-40° or >302°.
Looking forward to testing more modifications in back-to-back comparisons with ECM provided data, instead of Android apps and proprioception.
