If you like doing things yourself, then you might want to consider using one of the Autel Automotive Diagnostic Scanners to diagnose any potential problems your vehicle may be experiencing. By doing this yourself, you can save lots of money knowing what type of repair that is needed on your vehicle. It’s important to know what is wrong with your car and this diagnostic testing tool will provide you with all the OBD2 type code information for a specific problem.
On-board diagnostics (OBD) is a system that relies on sensors and computers in your car to display vital information about how your car is operating. In its earliest days, OBD took the form of cooling system gauges, tachometers, oil pressure gauges, and fuel level indicators to give us basic information about a car’s condition. Nowadays, OBD systems can tell you about everything from crankshaft and camshaft position to manifold pressure to ignition misfires.
What is a Diagnostic Trouble Code (DTC)?
Diagnostic trouble codes (or fault codes) are codes that are stored by the on-board computer diagnostic system. These are stored in response to a problem found in the car by the system. These codes are stored when a sensor in the car reports a reading that is outside the normal/accepted range. The codes identify a particular problem area and are intended to provide you or the technician a guide of where the fault might be within the vehicle.
You should always check your service manual to discover which systems, circuits or components should be tested based on the code being returned.
Caution when Relying Only on Diagnostic Trouble Codes…
Parts or components should not be replaced with reference to only a DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. For example, if a DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself. DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
So to avoid unpredictable hazards when fixing a vehicle based on it’s DTC codes — make sure you get a reliable OBD2 reader that’ll thoroughly scan the vehicle for faults beyond traditional DTC codes.
Understanding OBD2 Codes
Using the OBD2 scanner is just the first step. You will need to learn how to read the code the tool has presented. You will be shown either an active code or a pending code. An active code alerts you to a malfunction that is keeping your check engine light illuminated. A pending code means that the OBD2 scan has failed an emission control system operation once, and if it fails again, your check engine light will be illuminated. At this point the malfunction will become an active code.
All the trouble codes displayed will start with one of four letters. “P” is for power train codes and covers the emissions’ system, ignition system, fuel system, transmission, and engine. “B” is for body and covers power seating, seat belts, airbags, and more. “C” is chassis related and will cover your axles, brakes, wheel pressure, suspension, etc. “U” is for network and other communication related issues.
The second digit lets you know if it is a OBD2 standardized generic code or if it is manufacturer specific. 0 means it is generic, and 1 means it is manufacturer specific. The rest of the digits will identify the exact problem you car is experiencing. Since there are literally thousands of fault codes, nobody will have them all memorized and your next step will be to consult a List of OBD2 Codes to find out what is wrong with your car.
