4. How to Use a Low Cost Car Diagnostic Scanner

What are the basic steps for using a car diagnostic scanner?

Using a car diagnostic scanner is straightforward. Here’s a step-by-step guide:

1. Locate the OBD-II Port: Typically found under the dashboard on the driver’s side.
2. Connect the Scanner: Plug the scanner into the OBD-II port.
3. Turn on the Ignition: Turn the key to the “on” position without starting the engine.
4. Power on the Scanner: Follow the scanner’s instructions to power it on.

7. Clear Codes (Optional): After addressing the issue, select the option to clear the codes and reset the check engine light.

4.1. Step-by-Step Guide to Connecting and Reading Codes

How do you connect the scanner to your car and read the diagnostic codes?

• Step 1: Locate the OBD-II Port: Find the OBD-II port under the dashboard. If you’re unsure where an OBD-II scanner plugs in, here’s how to find your car’s OBD-II port on North American cars. If you’re living elsewhere, here’s how to find your OBD-II/EOBD port worldwide.)
• Step 2: Connect the Scanner: Plug the scanner into the port securely.
• Step 3: Turn on the Ignition: Turn the ignition to the “on” position.
• Step 4: Power on the Scanner: Turn on the scanner and wait for it to connect.
• Step 5: Read Codes: Select “Read Codes” or a similar option in the menu.
• Step 6: View Codes: The scanner will display any stored DTCs.

4.2. Understanding Diagnostic Trouble Codes (DTCs)

What do the diagnostic trouble codes mean?

Diagnostic Trouble Codes (DTCs) are standardized codes used to identify specific issues within your vehicle’s systems. Understanding these codes can help you pinpoint the problem and determine the appropriate repair.

What is a DTC?

DTC is short for Diagnostic Trouble Code, which is the error code a car’s OBD system generates when it spots an issue. These are the codes read by OBD-II scanners that allow the user to figure out what’s going on under the hood. There are a lot of standardized DTC codes that are the same across different makes and models of vehicle, though some manufacturers employ their own DTCs that are unique to one or more of their vehicles

What do DTCs actually mean?

If you’re unfamiliar with how DTCs are written, then they probably look like complete gibberish – a random selection numbers and letters that mean very little to you. Fortunately there is some logic, which will give you an idea of what errors the car has detected.

The first letter confirms which of the car’s main systems is experiencing the issue. Those are the Powertrain (P), Body (B), Chassis (C) and Network (N). The second is a number designating whether this is a generic code (0) or a manufacturer specific code (1).

The third character then identifies exactly which system is experiencing the issue.

• 1 is fuel and air metering
• 2 is an injector circuit specific fuel and air metering code
• 3 is the ignition system or a misfire
• 4 is an auxiliary emissions code
• 5 concerns vehicle speed controls and idle control systems
• 6 is for computer auxiliary outputs
• 7, 8 and 9 are for transmission and gearbox faults
• A, B and C are for hybrid-specific propulsion faults

The fourth and fifth character then confirms the exact fault, and can be any number between 0 and 99.

OBD-II scanners are able to describe what these error codes mean, though more advanced models will be able to give you more information. It may require some time on Google, and as you can imagine there are a lot of possible DTC errors you may encounter. Over 5,000, in fact.

Not all DTCs are critical issues, though. While they will detail major problems experienced by your problem, the error code may just be warning you that the engine temperature is a little too high.

4.3. Clearing Codes and Resetting the Check Engine Light

When and how should you clear the diagnostic codes?

Clear codes only after you have identified and addressed the underlying issue. To clear codes:

1. Address the Problem: Fix the issue causing the DTC.
2. Connect the Scanner: Plug the scanner into the OBD-II port.
3. Turn on the Ignition: Turn the ignition to the “on” position.
4. Select “Clear Codes”: Follow the scanner’s instructions to clear the codes.
5. Verify the Reset: Ensure the check engine light turns off.

5. Advanced Features and When They Are Needed

What advanced features are available and when should you consider them?

Some car diagnostic scanners offer advanced features that can be beneficial for more complex diagnostics:

• Live Data Streaming: Monitor real-time data from various sensors and systems.
• O2 Sensor Testing: Evaluate the performance of oxygen sensors.
• EVAP System Testing: Check for leaks in the evaporative emissions control system.
• ABS/SRS Diagnostics: Diagnose issues with the anti-lock braking system (ABS) and supplemental restraint system (SRS).
• Bi-Directional Control: Activate or control specific components to test their functionality.

5.1. Live Data Streaming and Its Benefits

How can live data streaming help in diagnosing car problems?

Live data streaming allows you to monitor real-time information from various sensors, helping you identify intermittent issues or performance problems. By observing parameters such as engine temperature, RPM, and fuel trim, you can gain valuable insights into your vehicle’s operation.

5.2. O2 Sensor and EVAP System Testing

What are the benefits of O2 sensor and EVAP system testing?

• O2 Sensor Testing: Evaluate the performance of oxygen sensors, which are crucial for fuel efficiency and emissions control.
• EVAP System Testing: Check for leaks in the evaporative emissions control system, which can cause fuel odors and emissions problems.

5.3. ABS and SRS Diagnostics

When are ABS and SRS diagnostics needed?

ABS and SRS diagnostics are necessary when you experience issues with your anti-lock braking system or supplemental restraint system (airbags). These systems are critical for safety, and diagnosing problems early can prevent accidents and injuries.

5.4. Bi-Directional Control and Its Uses

What can you achieve with bi-directional control?

Bi-directional control allows you to activate or control specific components to test their functionality. This can be useful for tasks such as:

• Activating Fuel Injectors: Test the performance of individual fuel injectors.
• Controlling the Throttle: Check the throttle response and identify issues with the throttle position sensor.
• Cycling the ABS Pump: Test the operation of the ABS pump and valves.

6. Maintaining and Updating Your Car Diagnostic Scanner
