My Honda Element EX has a red air bag warning light that recently has turned on. Was hoping I could do the diagnostic myself using the tool, print out a report from my PC, then take that to the dealer. Readers for air bags, ABS, etc can be quite expensive. You can try searching online for PC apps and cables that might do it.

I'm hoping somebody has come up with one by now. I decided that I just didn't need my ABS working that bad as the car is only worth half of what the tool to diagnose it costs If you can find a cost-effective alternative, please make sure to come back and let us know what it is!

Interestingly, you can read the code without a scanner. For example if it blinks 5 time slow and 1 time fast you have a 51 code. All you'll need is a paper clip.

This video below will demonstrate how to do it. I just did this and it works great. Once you obtain the code you can go online and look up what it means. I have a Honda Element and I was actually able to just reset the light because the sensor misfired.

This video will show you how to reset the light:. I have an Innova Equus There are other brands out there as well, though I don't know how well those work. The Equus one I have works great. There are also the bluetooth options. I'm not sure how well they work, either. While these are options available, there may be better options out there. Just letting you know you do have options.I have a Ford explorer V8 I reset the check engine light and drive it for a couple days and no problem then here is the check engine light and stays on.

Any ideas! Take a look at this page!

Quick links Acura. Land Rover. How do I check engine codes without a scanner? Email This BlogThis! Determine Whether a Scan Tool Is Necessary If your vehicle is a model year or older, you will be able to check OBD-1 diagnostic trouble codes without using a dedicated scan tool.

To access OBD-1 codes, the vehicle's computer must be set to a special mode that allows display of the stored engine codes. The process varies by vehicle make, and can be found in the car's service manual or online.

The procedure may involve connecting a disconnected electrical connector, following a sequence of pumping the brakes, gas pedal or some other action before turning the ignition to the accessory position. When the vehicle's computer is in diagnostic mode, the malfunction indicator light MIL, or check-engine light will flash a series of short and long pulses separated by pauses.

Digits of the code are deciphered by counting the flashes of the light. The first digit will be composed of long pulses, the next digit with short pulses, and so on until a pause is encountered. Pauses signify the end of a code.

Subscribe to: Post Comments Atom.Getting one of the best OBD2 scanners can not only be a lifesaver when your car's "check engine" light comes on but also can provide rare insight into the deeper recesses of the vehicle's engine, transmission and other vital components. With this knowledge, those who are handy can often do many of the repairs themselves.

Those who are not so handy are no longer at the mercy of disreputable repair shops looking to inflate the bill as much as possible. After all, knowledge is power. We've looked at dozens of OBD2 scanners and rated them based on features, size, warranty, setup, ease of use and — above all — value.

These scanners can diagnose thousands of car problems, and they work on vehicles made since But all scanners are not created equal, with two general types of devices:.

In other words, having one of these devices is no longer a luxury you can't afford, but something you need to have in your car. After all, the next time you break down, it would be nice to know the cause before someone starts repairing it.

Out of the dozens of OBD2 scanners we've tested, the best not only show what's going on under the hood but also can perform extra car maintenance tasks while having greater longevity. Three scanners stand head and shoulders above the rest by going beyond the expected with helpful extra technology.

It does double duty by providing a small but efficient cabled handheld scanner for nosing around under the hood that also can wirelessly receive OBD data to serve as an auxiliary gauge inside the cabin to display key engine parameters.

It's also quite affordable. Meanwhile, the Autel AutoLink AL adds something that few scanners have: a handy electrical multimeter tester and test leads for tracking down everything from a faulty cable to checking on whether a fuse has blown. As innovative and helpful as it is, however, you can't use the scanner and multimeter at the same time, and the device needs to be periodically recharged.

Its large color screen, intuitive interface and battery test are complemented by a rugged design that should be able to stand up to abuse in the garage. It adds something the others lack: a lifetime warranty, which means that the SK could be the last scanner you'll ever need, regardless of how many miles you drive.

The best OBD2 scanner overall, Ancel's BD is just as good as a handheld scanner with a screen as it is when connected to a phone or tablet via Bluetooth. It can also augment the car's cockpit with a supplemental display of key engine parameters. Think of it as freedom-of-scanning choice. Small and lightweight, the BD measures 5. Its icon-based, 2.

They can be shown as numbers or graphs. It has a inch cable that makes it just as good for hanging over the hood looking for an engine problem as monitoring the engine while driving. On the other hand, the BD's rudimentary four-key interface can make navigation awkward. There's also a mode button on the side for selecting Bluetooth and cable operation.

This ODB scanner quickly connected with my Audi Allroad and displayed a graph of the engine speed along with other parameters. Later, it found my introduced fault and was able to turn off the car's check engine light. The Ancel BD includes a three-year warranty and can do so much more than single-purpose scanners. Autel's AutoLink AL is one of the best OBD2 scanners because it does something that most other OBD2 scanners can't: It can check electrical connections with a built-in multimeter to uncover pesky electrical shorts or burned-out cables.

Just note that the multimeter is a stand-alone function that doesn't work when the AL is connected to the car as an OBD scanner. The AL has connectors for the multimeter's included test cables for doing anything from checking continuity and current to voltage. The device's lithium-ion battery powers it for checking fuses, the alternator's voltage or the gas gauge. The AL not only shows live data, like engine speed, coolant temperature and other items but also can run a comprehensive preinspection readiness key.

It shows results as three lights for faults: red permanent faultyellow temporary fault or green no faults. Despite its soft rubber bumpers, the AL is fairly compact and light at 6. It has a unique pull-out leg so the device can stand on its own, as well as a generous inch cable.OBD2 trouble codes are part of a troubleshooting system that helps you track down the source of your engine's problems. For example, if the engine's computer recognizes a malfunction during operation, it isolates it, translates it into a code and saves it so you can access it.

You retrieve it using one of the methods outlined here. Let's say the code indicates a too-rich oxygen-to-fuel ratio. Look this up in a repair manual and you'll see this is usually liked to a faulty oxygen sensor.

Replacing it solves the problem and the code resets. Turn the ignition key "On" and "Off" without cranking the engine. How many times you do this depends on your particular vehicle. Most Chryslers require five times; other cars require three.

End with the key in the "On" position. Start the sequence anew if you accidentally crank the car. Watch the "Check Engine" or "Service" light on the dash. It will be lit, and will begin to pulse.

Each pulse represents a number. A pause separates one digit from the next in a two-digit code. For instance, Code 23 will go like this: pulse, pulse, pause, pulse, pulse, pulse. Write down the codes as they flash through the "Check Engine" light.

Each code has a meaning, directly related to a problem in the engine. Look up the codes in a repair manual. Depress the odometer "Trip" and "Reset" buttons while turning the key "On. Depress the odometer "Trip" and "Reset" buttons while simultaneously turning the ignition key "On" and "Off. Release the odometer buttons and read the trouble codes from the digital odometer. Locate the test port under the dash where the OBD2 scanner plugs in. Use a piece of jumper wire or even an unbent paper clip to link ports "A" and "B," initiating the diagnostic sequence.

Watch the "Check Engine" light for the codes to flash.

How to Read and Understand Check Engine Light (OBD-II) Codes

It must be a steel one, and not have any plastic coating on it. Using jumper wires to flash codes has been built in by the car manufacturers to ensure people without a Scan Tool or Code Reader can still diagnose the vehicle faults by reading the codes. Simply follow the step by step instructions which clearly show you which terminals on the diagnostic connector to link, and then insert the Paper Clip into those terminals. The picture to the right show a typical example of bridging 2 terminals of a diagnostic connector to start a Check Light flashing on the dashbaord.

The website pages will now generally ask you to turn the Ignition Key On. A Check Light on the Dash will now begin to Flash as shown in the diagram to the right. By using the code timing informationyou can now understand the pattern of the light flashes, and you can write down the code numbers as they are flashed in sequence.

You can then enter the code numbers into the final Codes Screen to get the code description code meaning. Some vehicles such as pre Mitsubishi's and Hyundai's, plus some Kia and Mazda vehicles do not display codes on a flashing dash light. These vehicles give thier code signals directly from the diagnostic connector.

You will need to use an LED tester or a Voltmeter to read the codes from these vehicles. You need the 10K ohm resistor to limit the current draw from the vehicles diagnostic lines.

The LED will still be bright enough to see flashing. Step 2 Solder one wire onto the bottom of the resistor. You should now have something looking similar to the picture below. If you choose you can now heatshrink the two LED legs and add Aligator clips to make it easier to connect to some of the vehicle diagnostic connectors.

To use the LED tester simply connect it to the vehicle as per this websites instructions. By using this websites code timing information, you can now understand the pattern of the LED light flashes, and you can write down the code numbers as they are flashed in sequence. You can then enter the code numbers into the Code Screen to get the code description code meaning.

The Black Jumper wire in combination with the loose terminals shown above is really useful for grounding terminals of vehicle diagnostic connectors, to output the codes. One of their main advantages is that they provide a stable ground, to ensure the vehicle stays in diagnostic mode to display the codes while you read them. The 3 loose terminals above are also really useful for accessing some diagnostic connector terminals that are hard to get to.
