Seven must- have car diagnostic tools

 

Hand with wrench. Auto mechanic.

These days, cars and trucks are more complex than ever. Not only are they jam packed with all of today’s most advanced mechanical components and features, but all of these sophisticated bits of machinery are all interconnected via computerized networks of interrelated car self diagnostic tools. These networks can be very useful in testing and diagnosing problems with your vehicle- but only if you have the right equipment. A lot of times, all this extra sophistication can seem like a great hassle- especially if you’re accustomed to the good old days of muscle-car simplicity where you just replace the part and fire it up. Well, for better or worse, those days are gone.

why need an obd2 scanner

The good news is there’s plenty of powerful tools available that- with a little bit of time in research- you can learn to perform complex diagnostic functions with that will give you a lot more power over the ins and outs of your car or truck than you would have had otherwise.

These Autel Scanner will give you the ability to figure out what is going on with your modern computerized vehicle, so that you can get it fixed and get back on the road.
7-1

1. Obd2 Scanner

An Auto Diagnostic tool is a diagnostic system that allows onboard computers in cars and trucks to tell you what’s wrong with the vehicle. This car diagnostic tool is used for a range of self-diagnostic and reporting purposes. Unlike the earlier, OBD-I system, the Obd2 system uses the same code designations, communication protocols, and connectors for cars made by all major manufacturers. The standardization has made the previous Obd1 almost completely obsolete.

2. Ignition Tester

Also known as a spark tester, this tool is absolutely indispensable for anything that relies on spark plugs- that means your car. Any time an engine won’t start, it’s possible that the reason is that there is no spark coming from the spark plug to get the engine started. An ignition tester allows you to diagnose the problem so that you don’t go all around your car solving every other problem whether you need to or not.

3. Airbag Tester

As you can imagine, it could be quite problematic to have a non-functional air bag and not know about it until the moment you need it. And naturally, testing your airbag by whacking your bumper with a rubber mallet is not ideal. Fortunately, there is a tool that can tell you whether or not all of the electronic components of your airbag system are working correctly without setting the safety device off.

4. Fuel Pressure Tester

Like a problem with your spark plug, a problem with low fuel pressure can cause your car or truck to fail to start- and if you can’t diagnose the problem directly, then you may have to work on several different things before finally finding the problem. A fuel pressure tester tells you where your vehicle’s fuel pressure is at, whether it’s too high or two low, enabling you to solve the problem straight away.

5. Timing Lights

A timing light is a special automotive stroboscope that mechanics use to set the ignition timing of internal combustion engines that are equipped with a distributor. Modern vehicle engines require timing lights to scan ignition timing accurately so that the timing can be adjusted to the optimal range for your vehicle.

6. Emission Analyzer

In most states, drivers are required to have their vehicles checked for proper exhaust emissions before the vehicle can be tagged and allowed to drive legally on public roads. Even if you are fortunate enough to live in a part of the country where vehicle emissions are not regulated, it still might be good for your conscience to have your emissions tested and adjusted accordingly. These Car Diagnostic Scanner are inserted into the exhaust pipe and, in addition to checking your emissions- they can also be used to diagnose a whole host of problems. It can also play an important role in certain safety checks, help with engine tuning, and certain kinds of repairs.

7. Vacuum Tester

A vacuum test is among the simplest Auto Scan Tools a mechanic can have. With a simple gauge, anyone can gain valuable insight into vacuum leaks, low compression, incorrect timing, and sticking valves just to name a few. You will need to know the vacuum specifications for your engine, and bear in mind that these gauges are adjusted for sea level. That means for every 1,000 feet your location is above sea level, you will need to subtract an inch of vacuum. The simplest check to perform is a running vacuum test. Simply start the engine and let it reach normal operating temperature. Find a vacuum port and connect the gauge. The port should be on the manifold or below the carburetor. It shouldn’t be on the air cleaner, high on top of the carburetor, or on any of the emissions control components.

Tool Review: AE Tools MicroPod II with WiTech software

The reviewer finds this scan tool and software are among his favorite factory tools due to the ease of use and the depth of coverage provided.

The Chrysler Micropod II diagnostic tool from AE Tools is small enough to fit in a shirt pocket and offers 100-percent CAN coverage for Chrysler, Dodge, Jeep and Fiat vehicle platforms, according to the manufacturer. This dongle-style, PC-based device can be used in place of the StarMobile, StarScan and WiTech Pod scan tools.
The Review

Martin Fay, president of The Motor Works of DeKalb in DeKalb, Ill., reviewed the AE Tools MicroPod II with WiTech software. Motor Works services and repairs domestic and imported vehicles, and Fay finds this scan tool and software are among his favorite factory tools due to the ease of use and the depth of coverage provided.

Fay says this tool offers him time savings when programming Chrysler vehicles. Before, when the shop needed to program Chrysler vehicle ECUs, they would make an appointment with a dealer a day or two ahead of time. Then, they would tow the vehicle to the dealership and wait at the dealership while the programming was performed. Now, they can perform the programming in-house, which can lead to days’ worth of time savings.

“The diagnostic time-savings is equally as large due to the superior organization and logical navigation of WiTech,” says Fay. In addition, the Chrysler MicroPOD II with WiTech software also supplies diagnostic repair information keyed to each trouble code.

He also likes the “ECU Not Built” function of WiTech software. “Knowing whether an ECU is communicating is critical to diagnosis.”

The most challenging job Fay used the MicroPod II with WiTech on was a 2007 Chrysler Pacifica. The vehicle, which was towed to the shop, had multiple dash warning lights on, the engine wasn’t cranking and the owner had previously replaced the powertrain control module (PCM). Fay says, “Using the MicroPod II and WiTech, we found several modules not communicating. The topology helped us determine which modules were talking on what buses. Having accurate code descriptions was also a great help.”

To diagnose this issue, Fay removed the non-functioning PCM, checked power and ground feeds to the unit and made corresponding repairs. “Repairs now allowed the Pacifica to crank and start, but immediately die. WiTech topology now showed a repaired PCM, but several other modules still failed to communicate, including the wireless control module,” says Fay.

“Removal of the wireless control module found a 12V feed wire missing. This had occurred when another party removed an aftermarket remote start. Wiring repairs now brought the remaining modules back online. The vehicle started and continued to run. The MicroPod II and WiTech software proved invaluable in this complicated diagnosis.”

Fay also uses this tool to program keys, wireless control and other modules, and to perform general diagnostics on many Chrysler vehicles.

Even though he had not used a previous version of this tool, Fay found the Chrysler wiTech MicroPod 2 and WiTech software easier to use than most factory scan tools currently on the market.

One of the tool’s greatest strengths, according to Fay, is the company’s support. “AE Tools will modem into your computer, install all the required files, perform the setup, ensure proper connection to the vehicle and then provide a mini lesson in the MicoPod II’s and WiTech’s use.

“Over time, Motor Works has experienced typical problems with scanner communication, programming, tool usage, etc.” He says, “All were solved with a call to AE Tools’ support line. We did not have to wait for a call back. Immediate help was obtained by staff who know their product inside-out. Compared to other support organizations, this is a dream.”

Even though the company offers support, Fay adds that it is up to the user to practice with the tool and maintain proficiency.

The MicroPod II from CnAutotool.com comes in a hard shell case with all required cabling, but Fay also suggests that the Flight Recorder button and cable would be good accessories to have on-hand. “They allow one to program the MicroPod II with a list of specific PIDs for recording during a road test. Once programmed, the laptop is disconnected from the MicroPod II and a push button is installed.

“When the technician or customer feels a problem occur, the button activates ‘recording’ mode. This data is then downloaded into the WiTech program for later viewing,” he adds. “This recording can help locate problems areas like a miss or shudder, that only occur when driving the vehicle.”

Although this tool ranks near the top of his personal list, Fay suggests the following adjustments could be made to improve the PID data graphing: “I would like to see cursors included for more accurate interpretation of data; the ability to move graph zero point (like Picoscope) would be a benefit; the ability to save graphs in video form and export them, without reliance on Flight Recorder would also be a great help,” he says.

Finally, he adds, “The inclusion of Guided Fault Finding like that of European scanners would make this tool near perfect.”
