INC Meaning OBD2: Understanding Diagnostic Trouble Codes

INC in OBD2 doesn’t actually stand for anything. It’s often confused with other abbreviations, leading to a lot of head-scratching. When you see “INC” related to your OBD2 scanner, it usually signifies an INComplete diagnostic test. This means the specific diagnostic monitor hasn’t run yet or hasn’t gathered enough data to complete its evaluation. Understanding what INC means in the context of OBD2 is crucial for effectively diagnosing and resolving vehicle issues.

A common misconception is that INC stands for “Increment,” “Indicator,” or even “Incident.” However, these are incorrect. INC simply indicates an incomplete monitor status within your OBD2 system. This is a normal part of the diagnostic process and doesn’t necessarily indicate a problem with your vehicle. Let’s dive deeper into the world of OBD2 and the meaning of INC.

After a few trips with varying driving conditions, most of these INCs should switch to “OK” or trigger a specific diagnostic trouble code (DTC) if a problem is detected. Remember, “INC” is simply a status indicator, not a trouble code itself.

What are OBD2 Monitors and How Do They Work?

OBD2 monitors are self-diagnostic tests that continuously run in the background of your vehicle’s computer system. They monitor various systems, including emissions, fuel system, and transmission, to ensure everything is functioning correctly. Each monitor has specific criteria that need to be met before it can complete its evaluation. This might involve driving at certain speeds, maintaining specific engine temperatures, or completing a certain number of drive cycles.

Why is My OBD2 Scanner Showing INC?

Several factors can cause an INC status on your OBD2 scanner. The most common reason is that the specific monitor hasn’t had the opportunity to complete its diagnostic test yet. This is especially common after recently clearing codes or disconnecting the battery. It’s important to allow your vehicle to go through several drive cycles under various conditions to allow the monitors to run their tests.

Other potential causes of an INC status can include:

• Recent repairs: If a component has been replaced, the corresponding monitor might show INC until it completes its evaluation.
• Driving habits: Consistent short trips might not allow sufficient time for certain monitors to complete their tests.
• Faulty sensors: A malfunctioning sensor can prevent a monitor from completing its cycle, although this will often trigger a DTC as well.
• obd2 errpt: While less common, certain errors within the OBD2 system itself can also cause an INC status.

How to Clear INC Status on OBD2

The most effective way to clear an INC status is to simply drive your vehicle. Make sure to vary your driving conditions, including highway driving, city driving, and idling, to allow the monitors to complete their tests. This typically requires several complete drive cycles.

“A complete drive cycle requires meeting specific criteria like reaching operating temperature, a certain amount of idle time, and variations in speed and load,” says automotive diagnostics expert, John Miller, ASE Certified Master Technician.

What if INC Persists?

If the INC status persists after several drive cycles, it’s essential to investigate further. It might indicate an underlying issue with your vehicle.

• Use an advanced OBD2 scanner: A more advanced scanner can provide more detailed information about the monitor status and any pending codes.
• Consult a professional mechanic: A qualified mechanic can use professional diagnostic tools to pinpoint the problem.
