The turn signals are an important safety feature that alerts other drivers of the rider’s intention to turn or change lanes. If the turn signals are not working, it can increase the risk of an accident.

To diagnose and repair the B1122 Harley code, it is recommended to take the motorcycle to a qualified technician. They can use diagnostic tools to identify the exact cause of the problem and take appropriate actions to fix it. Some common causes of this code include a faulty turn signal module, a broken wire in the turn signal circuit, or a malfunctioning turn signal switch.

Causes and Symptoms of B1122 Harley Code

Common Causes

When a Harley-Davidson motorcycle displays a B1122 code, it usually means there is a problem with the turn signal circuit. The most common causes of this code are a short to ground, output open, or output fault in the left or right turn signal. Other possible causes include a faulty turn signal module (TSM), turn signal security module (TSSM), or ignition switch. In some cases, the problem may be related to a wiring issue, such as a damaged or corroded connector or a broken wire.

Identifying Symptoms

When a B1122 code is present, the most obvious symptom is that the turn signals will not function properly. In some cases, the turn signals may not work at all, while in others, only one side may be affected. Another common symptom is that the key light may come on, indicating that there is an issue with the security system. Additionally, the rear signal lights may not work, while the front signal lights may still function.

To identify the specific symptoms of a B1122 code, it is important to perform a diagnostic trouble code (DTC) scan. This will allow you to read the code and determine what is causing the problem. You may also need to check the voltage of the battery and fuel pump to ensure that they are functioning properly.

If you are experiencing issues with your Harley-Davidson motorcycle, such as a B1122 code, it is important to address the problem as soon as possible. Failure to do so could result in further damage to your bike or even a potential safety hazard.

Troubleshooting and Fixing B1122 Harley Code

If you’re experiencing an issue with your Harley Davidson motorcycle where the right turn signal is not working, and you’ve pulled the codes to find that it’s a B1122, then you’re in the right place. In this section, we will go over some troubleshooting steps and fixing methods to help you resolve this issue.

Troubleshooting Steps

The first step in troubleshooting the B1122 code is to check the bulbs. If the bulbs are fine, then you should check the wiring harness. Look for any loose couplings, pinched wires, or rubbed insulation that may cause a short. If you’ve recently changed something on the bike, such as the bars, seat, or grips, then this may have caused the issue. Any time you move the wiring around, you can end up pinching something.

Another step in troubleshooting is to check the turn signal module (TSM) or turn signal security module (TSSM). These modules can sense a bad circuit on one of the turn signal circuits, which can cause the B1122 code to appear. If you suspect that the TSM or TSSM is the issue, then you should take your motorcycle to a Harley Davidson dealership for further diagnosis.

Fixing Methods

If you’ve determined that the issue is with the wiring harness, then you should trace the harness and repair any damaged wires. If you’re not comfortable doing this yourself, then you should take your motorcycle to a Harley Davidson dealership for repair.

If the issue is with the TSM or TSSM, then you may need to replace the module. Again, if you’re not comfortable doing this yourself, then you should take your motorcycle to a Harley Davidson dealership for repair.

In some cases, the issue may be with the turn signal switch or the turn signal relay. If this is the case, then you should replace the faulty component.

In conclusion, troubleshooting and fixing the B1122 code may require some time and effort, but it is very important to ensure that your motorcycle is operating safely and correctly. If you’re not comfortable doing the repairs yourself, then you should take your motorcycle to a Harley Davidson dealership for repair.
