Car Diagnostic Scanners

With so many code scanners on the market today, what features do you need for your code scanner to come equipped with in order to diagnose your vehicle? There are several manufacturers of code scanners out there today, the one in particular I will be reviewing is Actron because I believe their product line has the most useful features in its array of products. Their product line has models that fit the novice driver (“where is my engine”) to the advanced home mechanic. The features below are not on every model but I will highlight the features that are and are the ones I feel are most useful in diagnosing your car’s performance.

Cost Effective

Without a doubt, this has to be true. Your scanner has to be cost effective. There are many that you will find that are in the thousands of dollars but I see no sense in spending that kind of money when it is totally unnecessary. Your scanner should pay for itself when it saves you one, maybe two trips to the dealer having them tell you what is wrong.

OBDII Compliant

The Actron CP9135 AutoScanner features a large, easy-to-read LCD screen that displays the definition of the trouble code.  acsifsenegal  For ODB II compliant (1996 and later) vehicles, the Actron CP9135 AutoScanner provides trouble code data, then erases trouble code and turns the Check Engine light off. Although you may still have to fix the problem, the scanner turns off the “Check Engine” warning light on your vehicle’s dash so you will not be distracted while you resume your drive.

The Actron CP9135 AutoScanner is simple and easy even for a non-professional to use. The attached cable with OBD II 16-pin connector provides connections for both power and data, while the eight-foot cars-scanner  cable and the rugged housing are both oil-resistant and grease-resistant for added durability. The long cord that connects to the computer facilitates ease of use in tight spaces. Once connected, just press the “READ” key and the very user friendly menu displays a variety of information in a snap. Use the Monitor Status and Inspection / Maintenance (I/M) Readiness function to ascertain your vehicle’s chances of passing an emissions inspection. The I/M Readiness is a pragmatic function to use just before having your vehicle tested for compliance to the standards of a state emissions program.

One very important thing to take note of is cars-scanner   that all emission testing facilities will not pass any vehicle that has an illuminated “Check Engine” light at the time of the inspection – even if the light is only lit to remind you of an over-due oil change or a 60,000-mile tune-up. Using the Actron CP9135 AutoScanner, you can turn off the check engine light and clear  getsugarbalance the emissions test without any unnecessary hassle. The menu also reminds you of any pending DTCs and reads the status of the Malfunction Indicator Lamp. By reading the Malfunction Indicator Lamp status the scanner gives some insight into what might cause your Check Engine light to turn on in the near future. In this way, the Actron CP9135 scanner is also able to provide some preventive measures to help a non-professional user to monitor a vehicle’s on board systems.

OBDII refers to on board diagnostics in vehicles later than 1996. Basically auto manufacturers after 1996 equipped all their vehicles with the same mechanism to test the on board diagnostics (wow it only took roughly 100 years). So if your car was made 1996 and later, your scanner needs to be OBDII compliant.

OBD I Upgradable

But my car was made before 1996, what do I do? Well, it will depend on the make of your car because manufacturers were not consistent in how they obtained on board diagnostics from vehicles. Basically, a good, reputable scanner manufacturer (like Actron) will provide upgradable cables to attach to your scanner to hook up to pre 1996 vehicles based on the make of your car.


Overall, I would say that most scanners and readers on the market today are dependable. I mean, a scanner in it’s most basic form is simply reading codes that the car is giving to them. What happens after that is a different story. Now unlike some scanner manufacturers, Actron scanners have a 1 year warranty period so in the event you do have something go wrong you can trade it in for a new one.
