HC368 Pro Car OBD2 Scanner Code Reader Car Voltage Test Engine Fault Scan Tool

Finding a check engine light on the dashboard can be frustrating, especially when you have no idea what caused it. Instead of immediately taking the vehicle to a repair shop, an OBD2 scanner can help you understand what is happening inside the vehicle.

The HC368 Pro OBD2 Scanner is designed as a multifunctional automotive diagnostic tool for users who need more than basic fault-code reading. It combines OBDII/EOBD engine diagnostics, real-time data monitoring, battery testing, carbon deposit detection, fuel detection and maintenance assistance in one device.

The scanner supports 12V OBDII vehicles and offers support for 13 languages, making it suitable for both professional technicians and everyday vehicle owners.

OBDII/EOBD Engine Diagnostic Functions

One of the main purposes of the HC368 Pro is to provide comprehensive OBD2 engine diagnostics.

Read and Clear Engine Fault Codes

When the check engine light comes on, the first step is usually finding out which diagnostic trouble code has been stored.

The HC368 Pro can read engine fault codes through the vehicle's OBDII system and provide diagnostic information for further troubleshooting.

After the problem has been repaired, the scanner can also be used to clear applicable engine fault codes.

Why Is Fault Code Reading Useful?

A fault code does not always tell you exactly which component needs to be replaced. However, it provides an important starting point for diagnosis.

By checking the code together with live data and other test information, technicians can narrow down the possible cause of a vehicle problem.

Freeze Frame Data

The HC368 Pro supports freeze-frame data, allowing users to view vehicle operating conditions recorded when a fault occurred.

This can be useful for identifying problems that may not be present all the time.

I/M Readiness Check

The scanner can check the vehicle's I/M readiness status.

This is particularly useful when preparing a vehicle for an emissions inspection because it can show whether the required emissions-related monitors have completed their drive cycles.

Real-Time Data Monitoring and Graphing

Live data is another important feature of the HC368 Pro.

The scanner can display up to 120 pieces of real-time vehicle data, allowing users to monitor operating parameters while the engine is running.

109 Real-Time Data Stream Graphs

In addition to numerical data, the HC368 Pro supports up to 109 real-time data stream curve graphs.

Graphical data can make changes in engine parameters easier to understand compared with looking at numbers alone.

For example, technicians can observe parameter changes while the engine is idling, accelerating or operating under different conditions.

Historical Data Replay

The HC368 Pro also provides several history replay functions:

Fault Code History Replay

Previously recorded fault-code information can be reviewed for easier troubleshooting.

Data Stream History Replay

Historical live-data information can be reviewed to help analyze vehicle behavior.

Freeze Frame History Replay

Previously captured freeze-frame information can also be accessed for diagnostic reference.

These functions can be especially useful when a fault is intermittent and does not occur continuously.

Battery Testing Functions

The HC368 Pro is not limited to engine diagnostics. It also works as a 12V automotive battery tester.

Battery problems can cause starting difficulties, warning lights and unusual electrical behavior, so checking battery condition can be an important part of vehicle troubleshooting.

Battery Health Testing

The scanner can provide information including:

• SOC — State of Charge
• SOH — State of Health
• Internal resistance
• Current CCA

These parameters can help users understand the overall condition of the vehicle battery.

Battery Voltage Monitoring

The HC368 Pro can read vehicle battery voltage and monitor voltage changes.

This makes it possible to observe battery voltage during different operating conditions.

Battery Starting and Charging Tests

The scanner also supports:

• Battery starting test
• Battery charging test
• Vehicle battery performance testing

These functions can help determine whether a starting or charging problem may be related to the battery or the vehicle's charging system.

Supported 12V Battery Types

The battery tester supports several common battery technologies:

• Standard batteries
• AGM flat batteries
• AGM spiral/wound batteries
• GEL batteries
• EFB batteries

This makes the HC368 Pro suitable for testing a variety of modern automotive 12V battery systems.

Engine Carbon Deposit Detection

Carbon buildup is a common concern as vehicles accumulate mileage.

Carbon deposits can potentially affect engine performance and may be associated with symptoms such as difficult cold starts, unstable idling, abnormal acceleration behavior and increased fuel consumption.

The HC368 Pro adds an engine carbon deposit detection function designed to help users evaluate carbon-related engine conditions.

Why Detect Engine Carbon Deposits?

Excessive carbon deposits may affect engine operation and combustion efficiency.

Traditional diagnosis may involve observing symptoms such as:

• Difficult cold starting
• Unstable idle
• Engine knocking
• Abnormal acceleration noise
• Poor acceleration
• Changes in fuel consumption

The carbon deposit detection function provides an additional diagnostic reference, helping users better understand the engine's condition before performance problems become more serious.

An Additional Diagnostic Reference

Carbon deposit detection should be considered together with other diagnostic information rather than being used as the sole basis for replacing engine components.

Combining the results with fault codes, live data and physical inspection can provide a more complete picture of engine condition.

New Fuel Detection Function

Another useful addition to the HC368 Pro is its fuel detection function.

Fuel detection involves analyzing and evaluating fuel quality and composition to help identify potential fuel-related problems.

Why Is Fuel Quality Important?

Fuel quality can influence:

• Engine performance
• Combustion efficiency
• Fuel economy
• Emissions
• Engine operating stability

Poor-quality or contaminated fuel may contribute to abnormal engine operation.

The fuel detection function gives users another tool for checking potential fuel-related issues and maintaining vehicle performance.

Maintenance Assistance for Easier Troubleshooting

For users who are not professional mechanics, understanding diagnostic codes can sometimes be difficult.

The HC368 Pro addresses this with an added maintenance assistance function.

Professional Maintenance Guidance

When the vehicle has a problem or malfunction, the maintenance assistance feature can provide relevant maintenance guidance and suggestions.

This can help users better understand possible troubleshooting directions instead of simply seeing an unfamiliar diagnostic code.

For professional technicians, it can serve as an additional reference during the diagnostic process. For vehicle owners, it can make basic vehicle troubleshooting easier to understand.

Wide Vehicle Compatibility

The HC368 Pro is designed for 12V OBDII vehicles and supports a wide range of vehicles.

It generally supports:

• Most European vehicles from 2003 onward
• Most U.S. vehicles from 1996 onward
• Other vehicles equipped with compatible OBDII systems

However, actual compatibility can vary depending on the vehicle's model year, engine, market version and diagnostic system.

Before purchasing, it is recommended to confirm that the specific vehicle is compatible with the scanner.

13 Languages Supported

The HC368 Pro supports 13 languages, making the device easier to use for customers in different regions.

Multilingual support is particularly useful for workshops and technicians who work with vehicles and customers from different countries.
