The B1447 code is an error code frequently encountered by automotive technicians. It indicates a circuit open problem in the Wiper Park Sense, as detected by the Body Control Module (BCM).
Symptoms of this issue may include non-functional windshield wipers or wipers that do not park correctly.
The causes of the B1447 code can vary, but common culprits include damaged wiring, a faulty BCM, or a malfunctioning wiper motor.
To fix this issue, technicians should start by inspecting the wiring for any visible damage or loose connections. They may need to repair or replace damaged wiring.
If the wiring is in good condition, the next step is to test the BCM and wiper motor to determine if they are functioning properly. If either component is found to be faulty, it should be replaced.
Once the necessary repairs or replacements have been made, the code can be cleared and the system should be retested to ensure the issue has been resolved.
What does it mean
The B1447 code indicates a circuit open issue in the Wiper Park Sense of the Body Control Module (BCM). Ignoring this code can lead to malfunctioning wipers and compromised visibility in bad weather.
It can also affect other systems that rely on wiper position information. Promptly addressing the B1447 code is essential for vehicle performance and safety.
what are the symptoms
The B1447 code is associated with symptoms such as the Engine Light or Service Engine Soon Warning Light turning on, along with potential vehicle-specific issues. It is important to address this code promptly to avoid further problems and potential safety risks. Ignoring the code could lead to more severe issues, so it is recommended to seek professional help to diagnose and fix the problem.
Common signs of a faulty Wiper Park Sense, which may be the cause of the code, include wipers behaving erratically, not parking properly, or not functioning at all.
Resetting the B1447 code requires identifying and fixing the underlying issue. This may involve checking the Wiper Park Sense circuit for electrical connection issues, inspecting the wiring harness and connectors for damage, and making necessary repairs or replacements.
What are the causes
The B1447 code can be caused by several factors, such as a faulty Wiper Park Sense, an issue with the Wiper Park Sense harness, a poor electrical connection in the Wiper Park Sense circuit, a faulty Body Control Module (BCM), or other potential causes. It is important to address the B1447 code promptly to prevent further problems.
Here are some important points to consider:
- To prevent the B1447 code, regularly inspect and maintain the wiper system, making sure that all components are in good working condition. This includes checking for any signs of damage or wear on the Wiper Park Sense and its harness.
- Some people may mistakenly believe that the B1447 code only indicates a problem with the wiper motor itself. However, it can also be caused by issues with the Wiper Park Sense and its associated components. Therefore, a thorough diagnosis is necessary to accurately identify the main cause of the code.
What Tools are Needed to diagnose
To diagnose the B1447 code effectively, professional technicians need specific tools. Here are the tools commonly used for diagnosing the B1447 code:
- OBD-II scanner: This tool is necessary for reading and retrieving the B1447 code from the vehicle's onboard computer system.
- Multimeter: A multimeter is used to measure voltage, resistance, and continuity in the Wiper Park Sense circuit. It helps identify any electrical issues or malfunctions.
- Wiring diagram: Technicians rely on a wiring diagram to trace the circuit and locate any potential wiring faults or shorts.
To diagnose the B1447 code effectively, follow these steps:
- Connect the OBD-II scanner and retrieve the B1447 code.
- Inspect the Wiper Park Sense harness and connectors for any visible damage or corrosion.
- Use a multimeter to test the circuit for continuity and measure the voltage at various points.
How to fix Step by Step
Step 1: Start by checking the possible causes listed, such as a faulty Wiper Park Sense or a poor electrical connection in the Wiper Park Sense circuit.
Step 2: Visually inspect the related wiring harness and connectors, looking for any damaged components or broken, bent, pushed out, or corroded connector pins.
Step 3: If any issues are identified during the inspection, perform necessary repairs or replacements.
Step 4: Thoroughly inspect the wiring and connectors to ensure proper electrical connections.
Step 5: Avoid common repair mistakes such as overlooking damaged components or not addressing poor electrical connections.
