5.0 out of 5 stars Excellent tool, manual needs some editing (see note below), May 21, 2009
Verified Purchase(What's this?)
This review is from: Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles (Automotive)
First of all, I must state that the scan tool worked well for my cars. Once connected it will:

- display diagnostic codes
- erase ALL codes
- retrieve I/M readiness status
- display the VIN number on 2002 or newer vehicles
- rescan

The MS300 supports the OBD II or OBD2 (On-Board-Diagnostics II) system and it understands all OBD2 protocols that a car may use: PWM, VPW, KWP2000, ISO9041, EKWP2000 or CAN. Once the proper protocol is detected, the MS300 is ready to display whatever Diagnostic Trouble Codes (DTC) the car computer's memory may be holding.

It should be noted that:

# it only retrieves codes already stored in the computer
# it does NOT provide any 'real-time' monitoring
# it is completely stand-alone and no Web-updates are possible
# it does not have printing capabilities
# it is powered through the car's own DLC (Data Link Connector)

The manual while not completely accurate does offer sufficient information to successfully connect and operate the device. It also includes a printed list of over 1000 generic Diagnostic Trouble Codes (DTC) definitions. 8000 more manufacturer specific DTCs can be found on the CD with more information at the company's own Web site.

In my case, I was able to diagnose within minutes the source for the 'Service Engine Soon' warning on my dashboard:

P0442 - EVAP Emission Control System Leak (Small)

I erased the codes and, if the warning reappears, I will know EXACTLY what to tell the technicians.

Given that I purchased this during one of Amazon's lightning deals, the price was right and I feel that I am getting a lot of value out of this little tool. The manual's small shortcomings do not compel me to subtract a star so, it's a 5-star device for me. I am happy I ordered it.

It does NOT work on a Honda Insight 2010. No matter how many times I try, all I get is a 'LINK ERROR'.

The scan tool only reads the codes that are stored in the vehicle's computer. Don't blame the scan tool for the code the car set.

djtal....... WRONG. A mechanic read my friend's car as a faulty O2 sensor. My MS300 read it as a EVAP leak. Same car, same computer, different error codes. It also got the error code wrong on my car. Another EVAP leak code when the problem was the sensor by the catalytic converter.
