B2335 DTC Code: A Comprehensive Guide


In the world of automotive diagnostics, trouble codes play a crucial role in identifying and resolving issues in vehicles. One such code is the B2335 DTC code. In this article, we will delve into the details of this code, its possible causes, and the steps to diagnose and fix the problem. So buckle up and get ready for an in-depth examination of the B2335 DTC code.

Understanding DTC Codes

DTC codes, short for Diagnostic Trouble Codes, are alphanumeric codes that are generated by a vehicle’s onboard diagnostics system (OBD) when it detects a fault or malfunction. These codes provide valuable insight into the specific problem area, making it easier for mechanics and technicians to pinpoint and rectify issues efficiently.

The B2335 DTC Code Explained

The B2335 DTC code specifically relates to a fault detected in the vehicle’s body control module (BCM). The body control module is responsible for managing various electrical systems, such as power windows, locks, and lighting. When the BCM detects an issue within its circuitry or component, it triggers the B2335 code.

Common Causes of the B2335 DTC Code

  1. Faulty Body Control Module: One of the primary causes of the B2335 code is a malfunctioning body control module. Age, wear and tear, or electrical issues can contribute to the failure of this component, leading to the generation of the error code.

  2. Wiring or Connection Problems: Damaged or loose wiring and connections can disrupt the communication between the body control module and other vehicle systems. This can trigger the B2335 DTC code as well.

  3. Other Electrical System Issues: Sometimes, problems with other electrical systems, such as the power window or lighting circuits, can indirectly affect the body control module’s functioning. These issues can result in the B2335 code being recorded.

Diagnosing the B2335 DTC Code

When faced with the B2335 DTC code, it is crucial to follow a systematic diagnostic approach to identify the underlying cause accurately. Here are the steps you can take to diagnose the problem:

Step 1: Scan the Vehicle for Trouble Codes

Use an OBD-II scanner to retrieve the B2335 code and any additional codes that may have been recorded. This step provides valuable information about the specific area of concern and assists in the overall diagnosis process.

Step 2: Inspect the Body Control Module

Visually inspect the body control module for any obvious signs of damage or loose connections. Check for loose wiring or exposed wires that may indicate a wiring issue.

Step 3: Perform Component Testing

To verify if the body control module is indeed faulty, perform component testing using a digital multimeter. Follow the manufacturer’s guidelines to accurately measure voltage, resistance, and continuity across different BCM pins.

Step 4: Check Other Electrical Systems

Inspect other electrical systems, such as power windows, locks, and lighting, for any malfunctions. Repairing concurrent issues might resolve the B2335 DTC code as well.

Step 5: Clear and Reset the Code

Once any detected issues have been addressed, use the OBD-II scanner to clear the B2335 code from the vehicle’s memory. This step allows you to verify if the repairs were successful and if the code returns.

Resolving the B2335 DTC Code

Based on the diagnostic results, you can take appropriate actions to fix the problem causing the B2335 DTC code. The most common solutions include:

  • Replacing the Body Control Module: If the body control module is found to be faulty during the diagnostic tests, replacing it with a new or refurbished unit is often the most effective solution.

  • Repairing Wiring or Connections: If wiring or connection issues are identified, repairing or replacing the affected components can rectify the problem and clear the B2335 code.

  • Addressing Concurrent Issues: By resolving any other electrical system malfunctions detected during diagnosis, you may eliminate the underlying cause that triggered the B2335 code.

Remember, if you are not confident in performing these repairs yourself, it is recommended to seek assistance from a qualified automotive technician or mechanic.

Frequently Asked Questions

Q1: Can the B2335 code cause any other issues in my vehicle?

A1: In most cases, the B2335 code itself does not cause any noticeable drivability issues. However, if the fault within the body control module remains unresolved, it may affect the functionality of various electrical systems, leading to inconvenience or potential safety concerns.

Q2: Can I drive my vehicle with the B2335 code?

A2: It is generally safe to drive your vehicle with the B2335 code. However, if you experience any significant issues with electrical systems, such as power windows or locks failing to operate properly, it is advisable to address the problem promptly to avoid a potential breakdown or inconvenience.

Q3: Can a B2335 code be intermittent?

A3: Yes, the B2335 code can sometimes be intermittent, meaning it may not be present all the time. This can make diagnosis and repairs more challenging. If you experience intermittent issues related to electrical systems, closely monitor their behavior and seek professional help to identify the underlying cause accurately.


The B2335 DTC code indicates a fault within the body control module of a vehicle. By understanding the possible causes of this code and following a systematic diagnostic process, you can effectively diagnose and resolve the issue. Remember to rely on the expertise of qualified professionals if you are unsure about performing any repairs yourself. Taking prompt action to rectify the problem will ensure optimal performance and safety of your vehicle’s electrical systems.
