Volvo Fault Codes List: Identify And Fix The Issues Easily

Volvo uses unique alphanumerical codes to detect problems related to the engine, ABS, transmission, and many more. These codes can easily be detected by using the latest diagnostic scanners. So, what are the Volvo fault codes and how can you easily identify and fix the problems?

Volvo fault codes list includes unique individual codes to detect problems ranging from engine to transmission to control module. These codes are presented by the malfunctioning unit and a specialized scanner makes this code understandable to the user or mechanic. Each code needs a different solution.

Let’s dig deeper into the most common codes and their interpretation.

Volvo Fault Codes: List Of Common Fault Codes In New Generation Volvo

Volvo Diagnostic trouble codes (DTC) are easily understandable if you know the interpretation of each DTC. Most of the DTCs require a scanner that detects the origin of the fault and the type of fault.

Below are some common Volvo fault codes for the newer generation, including the XC70, XC90, S70, C70, and others with their interpretation and type:

What Does The Volvo Fault Codes Mean?

Volvo fault codes mean some combination of numbers that provide information about any defect or problem with your car, truck, or Volvo engine.

Whenever there is an internal or sensory issue with the engine, transmission, ABS, or braking the car stores the information, processes it, and expresses it as DTC.

These codes were first implanted in the engine to easily diagnose the origin of a problem. But later on, the large number of diagnostic codes became almost impossible to interpret.

What Is DTC & OBD?

DTC or Diagnostic trouble codes are the unique codes that your engine shows when there is an issue with the engine, transmission, ABS, or internal communication or control module.

DTCs were too complicated for people to understand without proper guidelines. That’s why international law made it compulsory for manufacturers to provide a code that will be understandable to users. This is where Onboard diagnostics or OBD was introduced.

OBD-ll system is currently available in the Volvo engines.

What Are The Types Of Volvo Error Codes

Volvo error codes are divided into four categories:

• B-codes: These codes are related to the body of the car. They include the seats, airbags, and seatbelts. 
• C-codes: These codes are related to the chassis. They include braking, suspension, and other part of the chassis.
• P-codes: These codes are related to the Powertrain and are most commonly found. They include the codes due to any defect in the engine and transmission.
• U-codes: U-codes are related to the integration of circuits and coordination between units. 

Why Do The Fault Codes Appear?

Volvo fault codes appear when the sensors detect any defect or fault in the functions of the components. If your Volvo loader, truck, or car faces any internal issue, the system recognizes the problem and sends a code to the OBD or scanner.

The problems can be due to any physical damage, wear, and tear, or due to regular usage.

How Can You Diagnose A Volvo Fault Code?

Diagnosing a Volvo error code requires a proper understanding of the system. Since the DTC codes are not readily understandable, you must equip your Volvo with a scanner or OBD.

Here’s how you can easily diagnose a Volvo fault code:

• First, you’ll have to look for a connector for the scanner. It’s mostly placed under the footwell.
• Put the car in accessory mode and connect the scanner.
• Put the scanner in ‘Read-only’ mode.
• Retrieve the code and follow the instructions.

Fault Codes Related To Engine

The fault codes will appear when there is any detection of a misfire, increased internal temperature, low engine coolant or fuel pressure, or defect in the regulation of exhaust gas.

Fault Codes Related To Transmission

The fault codes related to the transmission include altered gear ratio, slipping, and increased temperature of the transmission.

Fault Codes Related To Braking System

The fault codes related to the braking system include any malfunction of the braking fluid, braking pad, handbrake malfunction, brake booster, and others.

Fault Codes Related To ABS

When the ABS valve, control unit, or modulator starts malfunctioning, or the sensor for the wheel speed shows a defect, fault codes will appear on the display of OBD.

How Can You Resolve A Fault Code

Resolving a Volvo fault code requires proper diagnosis and interpretation of the code. Follow these steps to resolve a fault code:

• Once you’re done checking the fault code, research about it and find out the interpretation.
• Repair the affected part or get help from a professional.
• Clear the fault code.

How To Reset A Volvo Fault Code

You can easily reset a Volvo fault code if it keeps appearing after solving the issue. Here’s how:

• After putting the key in the ignition, press and hold the button for the odometer reset.
• While pressing the odometer, take the ignition to the next position.
• If the reset becomes successful, the service light will flash green.

Do These To Prevent Volvo Error Codes

It’s not possible to keep your car or truck away from any defect. But, you can be careful to minimize the damage and decrease the frequency of error codes.

• Keep yourself updated with the manual and the latest updates from Volvo.
• Don’t forget your routine checkup.
• Replace the damaged components regularly.
• Always check the coolant, brake oil, and radiator fluid level.
• Keep the wiring harness and connectors clean.

How To Read Volvo Fault Codes Without A Reader?

While the numerical DTCs require OBD for interpretation, you can read some fault codes without any OBD scanner.

In this case, you’ll have to look for the codes in the driver’s information center. Make sure to enable the power protection mode.

If you can diagnose the code from the information center, look for a possible solution in the user’s manual.

How Much Does It Cost To Fix A Fault Code?

The cost to fix a fault code can range from zero pennies to a hundred dollars. If the problem requires some communication defects, decreased fluid level, or other small fixes, it might not cost you any money.

In some cases, the engine’s DTCs require a professional fix. It can be somewhere between $20-$2000.

Do You Need To Worry About All Fault Codes?

No. Not all fault codes imply serious damage. Some are just precautionary and can be erased manually. They won’t cause any damage to the engine or other vital components.

Conclusion

Volvo fault codes list is essential to understand and fix common engine issues in Volvo trucks, cars, loaders, and engines. Newer OBDs can easily detect the DTCs and help you recognize the problem and take the necessary steps.

Volvo fault codes should never be ignored as some problems can have deteriorating sequels.
