Read & Erase DTCs
This code reader can pull diagnostic trouble codes that caused the Check Engine Light to turn on, and tell you the source of the fault. You may find a misfiring engine before it becomes a big problem. Once repairs are made, you can use it to clear the codes and so turn off the light.
I/M Readiness Check
Another handy feature in this scan tool is “I/M Readiness Test (for Inspection and Maintenance)”, the simple yet powerful self-check routines. It shows the emission-related sensors’ running status to tell whether your vehicle will pass the smog test or it’s time to have the maintenance.
O2 Sensor Test
If you find a drastic drop in fuel mileage then you can use this LAUNCH scan tool to see if the O2 sensor is defective. Replacing a defective O2 sensor can prevent possible damage to the catalytic converter. FYI, the catalytic converter would cost you thousands of bucks to replace.
Built-in DTC Library
When the code is displayed, the scan tool will show its description as well to help find the root cause of the malfunction. And if you don’t understand a specific error code, go through this OBD code reader’s DTC lookup library. No need to go looking it up online in a list or database.
Access to VIN, CID, CVN
You can get a wealth of car information including Vehicle Identification Number (VIN), CID and CVN by using this OBD2 scanner. It helps you to easily track the previous records of a vehicle, so you can get its historical data such as mileage to avoid buying a lemon car.
Live Data Stream
This scan tool will show you the live readout of what the PCM is receiving from the sensors while the car is running: RPM, fluid temperatures, fuel injection data, etc., which can aid diagnostics in all cases. For example, you can use it to diagnose why your car is losing gas mileage.
Freeze Frame Data
This OBD2 scanner can pull freeze frame data that capture what’s going on when an error code is triggered, covering important parameters such as engine RPM, vehicle speed, airflow, engine load, fuel pressure, etc. You’ll know exactly when the fault occurred and the affected sensors.
Customer Reviews
This code reader worked for my 1997 C1500 truck in diagnosing an engine performance, multiple misfire problem. I was thinking the problem was related to the mass airflow sensor. This code reader informed me that the mass airflow sensor was working correctly. Come to find out, there was excessive corrosion in the distributor cap. After replacing cap and rotor, engine is running great.
This is a very good scanner. I have couple OBD2 scanner which requires laptop. One requires serial port which non of my current laptop has. Another need USB to Serial cable which also needs driver which is very finicky. This LAUNCH OBD2 Scanner CR319 Scan Tool is awesome because it is standalone i.e.; it does not need any outside connection to the laptop. It does not require any battery either. It is very easy to use. Just plug it on the OBD2 port. Another big plus with this scanner is that the button is big. When you are working on your car with the gloves on, it is easy to use without removing gloves. If you work on your car, or want to know what is wrong with it, buy this scanner. It may pay for itself on the first time when you have to takeyour car somewhere.My car requires oil change on every 10k miles. After 5K miles, maintenance light comes on. When I take my car in every 5K miles in which time, they just inspect the car and reset the maintenance light, it cost more than this scanner. It pay itself when I do not have to take my car to the dealer.
Can reset/clear codes that trip the check engine light. Also can monitor the diagnostic tests as they reset from incomplete to ready/pass or fail.(Failing would throw another engine code)Great for DIY repairs before taking for smog check!

I left my gas cap on top of my car and drove away. I fortunately remembered and stopped my car put the cap back on and went on my way.The next day I started the car and my check engine light was on.I knew it had to be gas cap related so I inspected the gas cap and saw that the gasket was in bad shape.I purchased a new one and replaced, but The light never went off as it said it would according to the manual.So I picked up this scanner and sure enough as you can see in the photo it was just that.So for $25 I saved myself a lot of time and money going to the dealer which I'm sure they would have made it more than what it was.I highly recommend this scanner it is very user friendly and I love the screen it's very easy to read.
