The B1350 code indicates a problem with the Heated Backlite Relay in the Body Control Module (BCM). This can cause the heated backlite to not function properly. Symptoms may include the backlite not heating up or not turning on at all.
The code can be triggered by issues such as a faulty relay, wiring problems, or a malfunctioning BCM. To fix the problem, you will need to diagnose the specific cause using diagnostic tools. Once the cause is identified, you can replace the faulty relay, repair any damaged wiring, or replace the BCM if necessary.
It is important to address this issue as driving with a malfunctioning heated backlite can affect visibility and safety.
What does it mean
The B1350 code indicates a problem with the Heated Backlite Relay, as monitored by the Body Control Module (BCM).
This code specifically refers to issues with the relay that controls the rear windshield's heating function.
It is important to avoid common diagnostic mistakes when addressing this code, such as inspecting the wiring harness, connectors, and related components for damage or corrosion.
what are the symptoms
The B1350 code may cause the Engine Light or Service Engine Soon Warning Light to turn on. This code indicates a problem with the Heated Backlite Relay, as detected by the Body Control Module (BCM).
It's important to address this issue promptly to avoid any negative impact on the vehicle's performance.
Here are four ways in which the B1350 code can affect the vehicle:
- Reduced visibility: If the Heated Backlite Relay is not working properly, it can lead to poor visibility through the rear windshield, especially in cold or wet conditions.
- Electrical problems: The B1350 code can cause other electrical issues in the vehicle, such as malfunctions in the rear defogger or related systems.
- Inability to defog or defrost: A faulty Heated Backlite Relay may prevent the rear windshield from defogging or defrosting, which can be a safety concern.
- Increased accident risk: Reduced visibility and the inability to properly defog or defrost the rear windshield can increase the risk of accidents, especially in bad weather conditions.
It is recommended to have the vehicle diagnosed and repaired as soon as possible to ensure safe and efficient operation.
What are the causes
The B1350 code can be caused by a few different things. These include a faulty Heated Backlite Relay, problems with the wiring harness or connectors, poor electrical connections, a malfunctioning Body Control Module (BCM), or other factors that could be involved.
It's important to avoid common mistakes when diagnosing the B1350 code. Some of these mistakes include not considering the Heated Backlite Relay as a possible cause, failing to thoroughly inspect the wiring harness and connectors for damage or corrosion, neglecting to check for broken or corroded connector pins, and overlooking the possibility of a malfunctioning Body Control Module (BCM) as the root cause.
To effectively diagnose and fix the B1350 code, technicians should follow these steps. First, they should check the possible causes mentioned earlier, with a particular focus on the Heated Backlite Relay. Next, they should visually inspect the wiring harness and connectors for any signs of damage. They should also check for any damaged components and look for broken, bent, pushed out, or corroded connector pins. If necessary, they can test the Body Control Module (BCM) for any malfunctions.
What Tools are Needed to diagnose
In order to diagnose the B1350 code accurately, you will need specific tools. These tools are important for identifying the source of the problem and ensuring a proper repair. Here are four commonly used tools for diagnosing the B1350 code:
- Scan Tool: A scan tool is necessary to retrieve the diagnostic trouble code (DTC) stored in the vehicle's onboard computer system. This code provides valuable information about the specific issue affecting the Heated Backlite Relay.
- Multimeter: A multimeter is used to measure voltage, resistance, and continuity in the circuit. It helps technicians identify any electrical faults or open/short circuits that may be causing the B1350 code.
- Wiring Diagram: A wiring diagram is a visual representation of the electrical connections in the vehicle. It is used to trace the circuit and locate any potential wiring issues that may be affecting the Heated Backlite Relay.
- Circuit Tester: A circuit tester is used to check if the Heated Backlite Relay is receiving power and ground signals. It helps determine if the relay itself is faulty or if there is an issue with the power supply or ground connection.
Proper diagnosis is crucial for an accurate repair. Some challenges that may arise include intermittent issues or hidden wiring problems. By using the correct tools and following a systematic diagnostic process, you can ensure an effective and lasting solution to the B1350 code.
How to fix Step by Step
Step 1: Continuing from the previous subtopic, follow a systematic diagnostic process utilizing the necessary tools to effectively address and resolve the B1350 code.
Step 2: Start by visually inspecting the wiring harness and connectors related to the Heated Backlite Relay for any signs of damage. Look for broken, bent, pushed out, or corroded connector pins.
Step 3: Check for any loose or poor electrical connections in the Heated Backlite Relay circuit.
Step 4: If no visible issues are found, use a digital multimeter to test the relay for proper operation. Ensure that the relay is receiving power and that it is switching on and off as expected.
Step 5: By following these steps, you can effectively diagnose and fix the B1350 code.
What are the Common Diagnosis Mistakes
Common diagnosis mistakes can occur when dealing with the B1350 code if potential issues with the wiring harness and connectors are overlooked. These components are vital for the proper functioning of the Heated Backlite Relay circuit.
To avoid diagnostic errors and ensure an accurate diagnosis, consider these troubleshooting tips:
- Thoroughly inspect the wiring harness and connectors for any damage, such as fraying, corrosion, or loose connections. These problems can disrupt the electrical flow and lead to the B1350 code.
- Check for broken, bent, pushed out, or corroded connector pins. These issues can cause intermittent or poor connections, resulting in the malfunction of the Heated Backlite Relay circuit.
- Use a multimeter to test the continuity and resistance of the wiring harness. This will help identify any open or shorted circuits that may contribute to the B1350 code.
- Ensure that all components related to the Heated Backlite Relay circuit are properly connected and functioning correctly. Faulty components, like the Heated Backlite Relay or the Body Control Module (BCM), can trigger the B1350 code.
What is the Repair Cost
The repair cost for the B1350 code varies based on factors like labor rates and diagnosis. Diagnostic tools are needed to identify the issue accurately. On average, diagnosis takes 1 hour, and labor rates range from $75 to $150 per hour.
It's important to choose a reputable repair facility for a fair price and skilled technicians.
Can I drive safely with this code?
Driving safely with the B1350 code is not recommended. The code indicates a malfunction in the Heated Backlite Relay, which controls the back window defrosting. This can lead to visibility issues, especially in adverse weather.
It is crucial to address and repair the code promptly for the safety of the driver and other road users.
Conclusion
In conclusion, the B1350 code indicates a deviation from factory specifications in the Heated Backlite Relay. This deviation could potentially be caused by a faulty relay, open or shorted harness, or poor electrical connection.
To diagnose and repair this code, it is important to visually inspect the wiring harness and connectors for any damage. Additionally, checking the condition of components and connector pins for any issues is crucial.
The process of diagnosing and repairing this code may require approximately 1.0 hour of labor. However, the actual repair costs may vary depending on the specific issue and required parts.
In terms of safety, it is not recommended to continue driving with this code as it can affect the functionality of the Heated Backlite system.
