4. Setting Up Your Kobra Wireless OBD2 Car Code Reader

Setting up your Kobra wireless OBD2 car code reader is a straightforward process.

4.1 Step-by-step guide to connecting the scanner

1. Locate the OBD2 port in your vehicle (usually under the dashboard).
2. Plug the Kobra scanner into the OBD2 port.
3. Turn your vehicle’s ignition to the “ON” position (but do not start the engine).
4. On your smartphone or tablet, go to “Settings” > “Wi-Fi”.
5. Turn on Wi-Fi and connect to the Wi-Fi signal named “WiFi_OBDII”.
6. Launch your chosen OBD2 app.

4.2 Troubleshooting connection issues

If you experience connection issues, try the following:

• Ensure that the scanner is securely plugged into the OBD2 port.
• Verify that your device is connected to the “WiFi_OBDII” network.
• Force quit and relaunch the OBD2 app.
• For some older devices with outdated firmware sometimes this is the sequence needed to connect the device:
  1. Leave your vehicle’s ignition in the off position. Plug the Kobra™ OBD Scanner into vehicle’s OBD2 port.
  2. Turn your vehicle’s ignition to the ON position. On your device, go to “Settings” > “Wi-Fi”. Turn on your Wifi and Connect to the Wi-Fi signal named “WiFi_OBDII”. Please Note: it may take up to a minute to detect.
  3. Once connected to that Wi-Fi network, click the small blue arrow to go to the advanced settings for it. Set the IP Address to Static. Configure the IP address to 192.168.0.123 and the Subnet Mask to 255.255.255.0. and Router 192.168.0.10. Leave gateway and DNS blank. Then, go back and exit the settings.
  4. Start your car. In your App, configure the connection to use a custom TCP connection with IP 192.168.0.10 and TCP Port 35000.

4.3 Configuring the OBD2 app

Most OBD2 apps require some configuration to connect to the scanner. In the app settings, you may need to:

• Select “Wi-Fi” as the connection type.
• Choose the Kobra scanner from the list of available devices.
• Set the OBD App to either search for WIFI. If this is not done, then App won’t detect the scanner. This should be done on any OBD App, because they all work similarly.

5. Interpreting Diagnostic Trouble Codes (DTCs)

Diagnostic Trouble Codes (DTCs) are alphanumeric codes that indicate specific problems detected by your vehicle’s computer. Understanding these codes is crucial for effective vehicle diagnostics.

5.1 Understanding the structure of DTCs

DTCs typically consist of five characters:

• The first character indicates the system (e.g., P for powertrain, B for body, C for chassis, U for network).
• The second character indicates whether the code is generic (0) or manufacturer-specific (1).
• The third character indicates the specific subsystem (e.g., fuel system, ignition system).
• The fourth and fifth characters indicate the specific fault within that subsystem.

5.2 Common DTC categories

Common DTC categories include:

• P0xxx: Generic powertrain codes
• P1xxx: Manufacturer-specific powertrain codes
• B0xxx: Generic body codes
• B1xxx: Manufacturer-specific body codes

9. Common Issues and Troubleshooting Tips

While Kobra wireless OBD2 scanners are generally reliable, you may encounter some common issues.

9.1 Scanner not connecting to the vehicle

• Ensure that the scanner is securely plugged into the OBD2 port.
• Verify that the vehicle’s ignition is in the “ON” position.
• Check the OBD2 fuse in your vehicle’s fuse box.

9.2 Scanner not connecting to the app

• Ensure that your device is connected to the “WiFi_OBDII” network.
• Verify that the OBD2 app is configured to connect to a Wi-Fi OBD2 scanner.
• Force quit and relaunch the OBD2 app.
• Turn Off WiFi On the Device. Disconnect the OBD Scanner from the Car. Force quit the app. Then close the app With Android, use “Task Manager”. With iOS, double-click the home button. Then launch the app again reconnect the WiFi and see if it connects.

9.3 Inaccurate or missing data

• Ensure that the scanner is compatible with your vehicle’s make and model.
• Verify that the OBD2 app is up to date.
• Try a different OBD2 app to see if the problem persists.

9.4 Check Engine Light Stays On

• If you are experiencing difficulty clearing a particular code, try placing your car in ACC mode (second ignition position). Remember clearing a code does not fix the problem and your car’s system will most likely detect the problem again at some point.

9.5 Unable to Read Fault Codes

• While the Kobra Scanner is compatible with 99.93% of automobiles made past 1996, it could be that your vehicle requires more specialized equipment to read the fault code.

9.6 Scanner Device Detected, but Not Connecting to Car

• In this case your vehicle may not be OBD2 compatible. If your vehicle (any brand) is made/imported AFTER 1 Jan, 1996 then it is 100% OBD2 compliant. If your vehicle is not OBD2 compliant, then only option is to take it to mechanic for them to use their $3000+ scanner like SnapOn.
