If you own a Harley Davidson motorcycle, you might have come across the error code B1306. This code indicates a short in the rear hand controls, specifically the switch for the volume up button. The BCM (Body Control Module) of your motorcycle has detected an issue with the electrical circuit of the switch, which can cause problems with the audio system of your bike.
When you encounter the B1306 code, it is important to address the issue as soon as possible. If left unchecked, the short can cause further damage to your motorcycle’s electrical system and even lead to a complete failure of the audio system. The good news is that this error code is relatively easy to troubleshoot and fix with the right tools and knowledge. In this article, we will provide you with the information you need to diagnose and repair the B1306 code on your Harley Davidson motorcycle.
Understanding Harley Codes
If you own a Harley-Davidson motorcycle, it’s important to understand the diagnostic trouble codes (DTCs) that your bike may display. These codes can help you identify any issues with your bike’s systems and components, including the Body Control Module (BCM).
DTC and BCM Basics
DTCs are alphanumeric codes that are used to identify specific issues with your bike’s systems and components. Each code consists of a letter and a series of numbers that indicate the specific problem. The BCM is the module responsible for controlling the electrical systems in your Harley, including the radio, instruments, and more.
When your bike’s onboard diagnostic system detects a problem with a system or component, it will generate a DTC and display it on your bike’s odometer. You can access these codes by pressing and releasing the trip odometer trigger switch.
Common Harley DTCs
One common DTC that you may encounter is B1306. This code indicates a problem with the radio speaker output circuit. This issue can cause the radio to stop working or produce distorted sound. To fix this issue, you may need to replace the radio or speaker.
Other common DTCs that you may encounter include:
- P Codes: These codes indicate a problem with the Engine Control Module (ECM).
- C Codes: These codes indicate a problem with the Anti-Lock Braking System (ABS).
- U Codes: These codes indicate a problem with module communication.
If you encounter a DTC on your Harley, it’s important to consult your owner’s manual or a qualified mechanic to determine the cause of the problem and the best course of action to fix it.
In conclusion, understanding Harley codes is an important part of maintaining and troubleshooting your Harley-Davidson motorcycle. By familiarizing yourself with these codes and the BCM, you can identify and address any issues with your bike’s systems and components quickly and effectively.
Diagnosing B1306 Code
If you are experiencing issues with your Harley Davidson, and the B1306 code appears on the diagnostic system, it means there is a problem with the power door memory output circuit. The B1306 code is commonly associated with power door locks, and it indicates a malfunction in the memory output function. To diagnose and troubleshoot the B1306 code, you need to understand the symptoms and possible causes.
Symptoms of B1306
The most common symptom of the B1306 code is the failure of the power door locks. If you are unable to lock or unlock your Harley Davidson’s doors using the remote control, it may be due to the B1306 code. Additionally, you may also notice that the power door locks are not working as they should, or they may be operating erratically.
Troubleshooting B1306
To troubleshoot the B1306 code, you need to start by checking the rear hand controls. The B1306 code is usually caused by a short circuit in the rear hand controls. Check the wiring and connections in the rear hand controls and ensure that they are not damaged or corroded. If you find any issues, repair or replace the damaged components.
If the rear hand controls are not the issue, you can move on to check the power door lock actuators. Check the wiring and connections to the actuators and ensure that they are not damaged or corroded. If you find any issues, repair or replace the damaged components.
Another possible cause of the B1306 code is a faulty BCM (Body Control Module). If you have checked the rear hand controls and power door lock actuators and found no issues, it is recommended to take your Harley Davidson to a professional mechanic to check the BCM.
In conclusion, the B1306 code is a common issue with Harley Davidson’s power door locks. If you are experiencing issues with your power door locks, and the B1306 code appears on the diagnostic system, you need to diagnose and troubleshoot the issue as soon as possible. Check the rear hand controls and power door lock actuators for any damage or corrosion, and if you find any issues, repair or replace the damaged components.
