What Kind of Issues Can a Diesel Diagnostic Tool identify?

A diesel diagnostic tool is a valuable investment for truck drivers and mechanics. A high-quality system can improve the efficiency of diagnosing and repairing equipment. Here is what you need to know about diesel diagnostic scanners and the issues they identify:

How They Work

Modern diesel vehicles come with onboard diagnostic systems (OBD). This computer system gathers data from the car’s sensors. When you plug a diesel diagnostic instrument into the OBD port on a truck, it makes the OBD a truck diagnostic code reader.

The diagnostic scanner reads the trouble codes and analyzes the engine and other crucial systems. Once the problem has been located, the diesel scanner notifies the user. Simpler diagnostic tools will only extract diagnostic issue codes. It is then up to you to investigate them and determine what repairs are required. More advanced diesel diagnostic tools can identify problems and suggest necessary fixes. Riteway Auto Patchogue also use this tool kit. One of their customers mentioned about it in Google Review of Riteway Auto Patchogue.

Who Can Use Them

Diagnostic tools are accessible to everyone. Investing in a diagnostic scanner can be wise if you own or drive a commercial vehicle. Even a more basic version allows you to find flaws, assess their importance, and take necessary actions. All truck repair and maintenance shops must have advanced diagnostic tools to cater effectively to their clients’ needs.

What Issues They Detect

Driving can be unsettling if the dashboard flashes with various symbols. Connecting a diagnostic scanner can help to identify the problem immediately. It can also tell you whether you can fix it yourself or if you need to find a repair facility. A diesel diagnostic scanner can be helpful if you spend extended periods traveling.

A diagnostic tool scans the distinct parts of a vehicle, including:

  • Engine
  • Brakes
  • Transmission
  • Exhaust

Diagnostic scans can also identify any performance problems with the following:

  • Gasoline injector
  • Throttle for airflow
  • Spark plug coils
  • Coolant

Here are six issues a diesel diagnostic scanner can identify:

1. Fuel Injection Problems

Are you having a difficult time starting your vehicle? Is there a misfire when you turn the key? Or is there a smell of fuel? These and other symptoms point to fuel injector issues. A diagnostic tool can help identify problems such as dirty, clogged, or leaky fuel injectors.

2. Diesel Particle Filter (DPF) Problems

Is your fuel consumption higher than you expect? Are the transmission and engine temperatures too high? Are you struggling with your engine performance? This could indicate the DPF is not regenerating correctly due to the DPF sensor failing. Using a diesel diagnostic scanner, you can identify DPF sensor failure.

3. Exhaust Emission Faults

Is the amount of exhaust emissions alarming? Or is the emission too sooty? A diagnostic tool can detect possible causes, such as a plugged fuel filter.

4. Engine Management Faults

The engine management light (EML) doesn’t signify a particular problem. When it comes on, it might be warning you about one or more issues, often related to exhaust emissions. Running a diagnostic check using a scanner can help show the exact cause of the problem.

5. Flat Spot Problems and Misfiring

Flat spot problems and misfiring issues could occur because of the following reasons:

  • Presence of diesel fuel contaminants like water, dirt, or oil
  • Leakage in the high-pressure fuel lines
  • Low fuel supply pressure
  • Air in the fuel system
  • Improper valve lash adjustment
  • Defective fuel injection nozzles or unit pump

Using a diesel diagnostic scanner can help you identify the exact cause of the misfiring issue. You can learn about Google Review Riteway Auto Patchogue to make the final decision.

6. Anti-lock Braking System ASB Faults

When the ABS indicator light glows, there could be issues with your vehicle’s ABS. The dashboard ABS light should turn on for a few seconds after starting your truck. If it doesn’t turn off, there might be a short-term problem.

If the ABS light suddenly starts to illuminate when driving, it may be a sign that one of the ABS’s parts has failed. When you use a diagnostic scanner, you can identify specific ABS faults. The ABS light sets off a code that identifies the particular ABS part that is malfunctioning.

Which Diesel Diagnostic Tool to Use

There are different scanners available for use by truck drivers and mechanics. Drivers can work with basic diagnostic tools, while mechanics require advanced options. Find a diesel diagnostic tool with all the features that cater to your needs.
