Next, the scan tool will be used to monitor the misfire counter for cylinder 4. Then, the scan tool will be used to look at the long-term fuel trims to see if fuel issues are present and the intake air pressure checked to see if vacuum leaks are present.

Mac Tools 505 North Cleveland Avenue Suite 200 Westerville, Ohio 43082. • All System DTC Scan will scan all available controllers on the selected vehicle for DTCs. I've never heard of anyone having problems disabling misfire CELs with the 32-bit ECU as long as they also disable both P0000 codes. I wouldn't even bother with Ecuexplorer in reading codes. I would make sure that when you did try using a true obdii scanner (if you did) then you disabled both the misfire codes AND the P0000 codes. How to Read and Understand OBD Codes. You're cruising down the road, enjoying your drive, when all of a sudden that most mysterious of indicators turns on: 'Check Engine'. Obtain an OBD-II scan tool. P0301 indicates a misfire condition on cylinder #1. The P indicates it's a powertrain code, the 0 indicates that it is a. After pairing the scan tool with my phone over Bluetooth, I started the truck and let it run for a few minutes then clicked 'Test Results' in the Torque Pro app. The individual cylinder misfire info on our trucks will show up in Test Results under TID $53.
The OTC Encore diagnostic scan tool, No. 3893, helps technicians repair vehicles faster with its AutoDetect system. The system searches several on-tool and Internet databases, providing the most likely vehicle fix based on more than 30 million vehicle-specific and experience-based fixes. The benefits of AutoDetect, found only on the OTC Encore and Genisys Touch, include tapping into the Identifix database and various technician networks, and automatically incorporating Google searches to help technicians find and make a vehicle fix quickly. These searches are automatically performed by the tool, not the technician, to provide the right fix specific to vehicle make and model. Encore combines domestic, Asian and European vehicle coverage on an Android platform, quickly reading codes and providing the most likely fix. The tool also includes several training videos to guide a technician through repairs.
The Review
Matt Skundrich, owner of Mobile Advanced Diagnostics & Programming in South Orlando, Fla., recently reviewed the OTC Encore with Bravo 2.0. He found the tool to be an overall time-saver due to its quick boot-up time and the ability to switch modes quickly. He also found the tool’s navigation to be straightforward.
“It’s so easy, a caveman can do it,” says Skundrich. “I have multiple scanners, about 12 in total, and this is the first one I grab because it’s so simple to use and always has the features I need to complete the job.”
To set up the scan tool out of the box, it needs to be registered. Skundrich also says there may be an update or two that will download with use. The Encore came with instructions on how to charge the battery and where users can download the manual, if needed. Skundrich downloaded the manual, but because of the tool’s ease-of-use, he hasn’t yet found a need for it.

On a daily basis, Skundrich travels to shops and helps diagnose vehicles they may be struggling to repair, or if they have a “very random problem.” He says he finds the information in the tool is great and can fix the vehicle’s issue without having to use additional resources. https://treestudy764.weebly.com/best-tool-for-photo-recovery-for-mac.html.
“If you have Identifix, you can load your login (information) into the tool and it will allow you to go straight into Identifix with the make/model car and code information.” He says this is the most beneficial use of the tool because he is able to fix the vehicle without having to walk away.
Skundrich most frequently uses the Encore on Chrysler, Ford, General Motors, Honda, Nissan, Toyota and Volkswagen makes. Specifically, he has used the tool to diagnose a misfire on a 2006 Nissan Sentra and a 2009 Mercury Mariner. In the case of the Mercury Mariner, the shop had already replaced the coil and plug on cylinder 6, but the vehicle was still misfiring. He used the tool to complete a relative compression a test, which showed cylinder 6 had low compression.
Skundrich has also used to tool to re-calibrate the steering angle sensor on a Nissan Xterra using the “repair trac” feature, which he says is the most powerful feature of the tool. Download tool for mac. “To give you an idea about the time I save, the other day I was working on a 2012 Nissan Xterra that had a code for a steering angle sensor. The top reported fix was to calibrate the sensor. Since the tool is already connected, it was all of three seconds to perform this function,” says Skundrich. “The code was corrected and I was off to another car. I never walked away from the car; this saves valuable time throughout my day.”
One of the companion features to the repair trac feature is the diagnostic information menu, which gives users the most common information shops look up. According to Skundrich, this includes: drive cycles, PCM pin out, TSB, tune-up specs, key programming, battery disconnect, oil light reset and more. “This saves me time, which saves me money because I don't need to go get my laptop to look this information up.”
Additional of the features that Skundrich likes are the all-code scan and system test. “Both of these get all codes,” he says. The system test also goes through all modes in OBD-II to see what has and has not run. The tool runs mode 06 to see if a code is about to set. Skundrich also likes that the tool can code injectors for Ford, Chevrolet and Dodge diesels and can program the VIN on Chrysler vehicles and more.
Prior to the Bravo 2.0 update, Skundrich purchased the Encore “because it was a great deal for what it did.” He adds that the first version had bugs and other issues. Because of this, he set the tool aside. “When I heard about the update to Bravo 2.0, I decided to pull out my tool. It seems OTC got on the ball and fixed all the bugs and issues along with improving the abilities of the tool.”
As a way to improve the tool, he would like to be able to initialize air bag modules. He also suggests seat calibrations and an all-code clear function be added in the menu, in addition to an improvement in the Auto-ID functionality. “The Auto-ID is not as strong as (some) other scan tools, but it works on most vehicles,” he says.
Even though Skundrich believes there is always room for improvement, he says, “The more I used it and compared it to others, I realized this was the best bang-for-the-buck scan tool I own.”

TOOLS USED:
Fuel injectors do not go bad like they used to and engines routinely last 200,000 miles when maintained properly. Usually, when a misfire occurs on a vehicle these days, the easy assumption to make is to replace the coil in the cylinder setting the misfire DTC.
However, the PCM might misinterpret the CKP sensor and set a misfire DTC for the wrong cylinder. Furthermore, bad engine compression and irregular injectory spray patters can affect ignition in the cylinder. Adware removal tool for mac.
Thankfully, with the right tools and techniques, ignition misfires can be diagnosed with almost 100 percent certainty rather quickly.
2006 Scion xB bad ignition coil
Unlike Fords, Toyotas are not quite so notorious for bad ignition coils. So, when one of these vehicles rolls into the shop with a misfire, you probably assume the vehicle needs spark plugs. This is because customers presume their Scions are like most other vehicles and only need spark plugs once every 100,000 miles, as opposed to 30,000 miles such as their factory maintenance schedules call for.
What do you do if after the 'tune up' the misfire remains? The following steps cover how to quickly discern the cause of the misfire.
1. Check which cylinder is misfiring
Using a scan tool, check the misfire DTC. Depending on the scan tool (and vehicle) you might be able to count misfires using Mode 6, as seen in Fig. 1. On some vehicles, a relative compression, cylinder power balance and fuel injector flow test can be done with a click of a button. These tests help the technician quickly find out which cylinder is misfiring and depending upon the bidirectional controls offered by the scan tool, narrow down if the misfire is caused by an ignition, fuel or mechanical issue.
2. Test the suspect ignition coil![]()
Testing ignition coils is an uncomplicated process, though ignition waveform interpretation can be quite complicated. For reasons of space, we are not going to discuss every nuance of interpretting an ignition waveform. Instead, we will cover both the old school and new school in ignition diagnostics.
Old school. You will need a labscope, wiring diagram and a T-pin to diagnose ignition the old school way. With the vehicle off, use a wiring diagram to find out which wire on the harness is the ground to the ignition coil, such as that in Fig. 2. Then, simply slide the T-pin into where the ground wire merges into the connector. (See Figs. 3A and 3B.)
It should be noted that if you do not have access to an accurate wiring diagram, simply keep putting the T-pin into a different wire until you get an ignition signal with the vehicle running. You will get a waveform on both the ground and power sides of the ignition circuit, so it is a matter of preference which side you choose.
Do this to each coil using different leads so you can compare ignition waveforms from different ignition coils. The more channels your labscope has, the better.

As Figs. 4 to 6 show, an ignition waveform looks different on different OEM applications. However, you generally do not need to memorize a known good waveform. A bad coil will simply stick out like a sore thumb, looking different than the other ignition coils. Even in Figs. 7 to 8, where not a single coil looks alike, the one that was misfiring has much more voltage and it matches up with the msifire DTC on the scan tool.
It is important to note that when looking at an ignition waveform, the large spike in the beginning of the waveform is the firing voltage. On a current waveform, the waveform will be at its lowest point, because as voltage increases amperage falls.
Using A Mac Scan Tool For Misfire Counter-strike
The long line of voltage follwing the firing voltage is the firing time, which is the time elapsed when the spark is actually occurring. Differences in firing voltage and other parts of the waveform reflect conditions in the cylinder.
New school. Don't feel like looking up wiring diagrams or hooking stuff up? Simply use a GTC SmarTach+ COP tester. (See Figs. 9 and 10.) By placing its probe on the top of an ignition coil, it instantly gives an engine RPM, burn time and coil kV reading. So, instead of comparing waveforms, you simply comprare burn time and coil kV between coils.
This method can also be used to check misfirng cylinders on vehicles that use spark plug wires. The probe can be pointed at different spark plug wires. All the technician needs to do is compare results.
3. Swap coils and test again.
It is important to note that regardless of whether you are diagnosing ignition the old or new school way, ignition is always affected by conditions in a cylinder. So, low cylinder compression from a washed down cylinder can make a good coil look bad. (See Fig. 11.)
Simply swap a known 'good' coil with the suspect one, and check again your readings. If the misfire changes cylinders, simply replace the suspect ignition coil. If it doesn't, the vehicle has a fuel or mechanical problem in that cylinder.
Presuming the reading does not change, the next step would be to remove the spark plug and do a compression test. If the vehicle does not have a dead misfire, it might be wise to check timing with a pressure transducer or do a cylinder leak down test. Now, if everything checks out, it is time to start testing the fuel injectors.

As for this 2006 Scion xB, the misfire changed cylinders, so it was fixed with a new coil.
