Recently I found out that an OBD2 scanner won’t connect with an in-dash navigation system. When I tried to read the diagnostic scan, it gave a lot of error messages and the scanner would not respond. This happened after I installed the new GPS system. I’ve also had other systems fail, so this is not entirely surprising. However, I realized something was off and went to find the issue on my own.
I hadn’t taken the car into any shops to have the problems fixed before I realized the scanner wouldn’t connect with the GPS device. It turns out the problem was the wiring between the two systems. My dealership installed the system but did not make sure the wiring was properly connected. Either way, the GPS and scanner are supposed to work well together. Now I just need to get it working again.
The problem starts when you first start up the car. The scanner is powered on and scanning. The OBD2 device is also powered on. As soon as you switch the system on, the two devices start communicating with each other.
The problem lies in the communication issue. The connector on the dashboard is too close to the OBD2 connector. If the connector were any closer, the error messages would not be received. So the next time you open your dashboard, you’ll see the connection.
To fix this, I unplugged the scanner from the car and then reconnected it. Then I turned the device on again and started scanning. No problem. There’s only one thing left – I should install the connector again. Luckily, this is a pretty simple step. I rechecked the directions and everything worked like a charm.
However, this problem occurs more often than I think. Sometimes, I’ll realize that the connector isn’t installed – but I didn’t realize it was the problem before. When I do, I have to uninstall and reinstall the scanner to make sure the problem goes away. Sometimes, there’s just no way to get the OBD2 scanner to work.
For example, sometimes you need the scanner for an older vehicle model. They are not manufactured anymore and are obsolete now. You can still use these in order to capture the diagnostic trouble codes. In case, however, that you have a newer car, there’s no reason for you to settle for second best. Get yourself a modern OBD2 scanner and you can enjoy your car with full peace of mind.
Most of the manufacturers have come out with a scanner of their own. These devices can capture all the information about your car. You can find a wide range of choices online. Some of them are more expensive than others, though. So, take your time in researching for the right OBD2 scanner for your car model. Choose wisely and you should be able to solve your problem in no time.
As soon as you know the exact model of the scanner you need, the next step is to check compatibility. This step might seem like a no-brainer, but you’d be surprised how many people overlook this detail. If you have a car or truck from a certain brand, make sure that you choose the correct OBD2 scanner for the same car. This is very important, especially if you want to fix the problem with the same OBD software that the manufacturer uses.
Next, make sure that you have an OBD cable to connect your scanner to your computer. If you don’t have one, you might have to use an adaptor. After everything is properly set up, you will be ready to troubleshoot the problem. Now, let’s go over some of the common problems that can occur with your OBD scanner.
When your scanner is not working, one of the first things you’ll notice is a significant delay when the car is responding. For instance, when you start up the vehicle, it may take several minutes before it starts. You might also notice that it takes longer to accelerate or decelerate. Another thing you’ll notice is that the scan reports show minor issues and nothing major. But, if you take a closer look at the scan reports, you’ll see that there are several errors in the codes.
Now, if the scanner is not responding because the OBD cable isn’t attached to the system, try to unplug the scanner from the USB connector first. Then, try plugging the cable back in again. Sometimes, there are static or voltage issues related to the OBD connection. If you plug the scanner into a different port, you should be able to get it to work.
