What are the causes
Possible causes of the B1446 code include:
- A faulty wiper park sense
- A problem with the wiper park sense harness
- A poor electrical connection in the wiper park sense circuit
- A faulty Body Control Module (BCM)
To diagnose a faulty wiper park sense, you can follow these steps:
- Visually inspect the wiring harness and connectors for any damage.
- Check for any broken, bent, pushed out, or corroded connector pins.
- If needed, seek professional assistance for further diagnosis and testing.
Ignoring the B1446 code can lead to potential consequences such as the engine light staying on or other vehicle symptoms. It is important to address the underlying issue causing the code to prevent further damage or malfunctions. It is recommended to seek professional diagnosis and repair to resolve the symptoms and ensure proper functioning of the wiper park sense.
What Tools are Needed to diagnose
To diagnose the B1446 code, a professional technician will need specific diagnostic tools. These tools include a scan tool and a multimeter. These tools are crucial for identifying the problem causing the code and determining the necessary repairs.
Here's a breakdown of the tools needed:
- Scan tool: This tool is used to retrieve the diagnostic trouble codes (DTCs) stored in the vehicle's onboard computer system. It provides important information about the Wiper Park Sense circuit and helps pinpoint the exact cause of the code.
- Multimeter: A multimeter is used to measure electrical values like voltage, resistance, and continuity. It is used to test the Wiper Park Sense circuit for any open or short circuits, ensuring that the electrical connections are correct.
Depending on the specific vehicle and the technician's troubleshooting process, other specialized tools may also be required.
How to fix Step by Step
Step 1: Continuing the diagnostic process from the previous subtopic, the next step to address the B1446 code is to systematically troubleshoot and resolve the underlying issue.
Step 2: To diagnose the Wiper Park Sense circuit, start by visually inspecting the related wiring harness and connectors for any signs of damage. Look for broken, bent, pushed out, or corroded connector pins. Ensure that there is a secure electrical connection.
Step 3: If necessary, use a multimeter to test the continuity and resistance of the Wiper Park Sense circuit. This will help determine if there are any issues with the circuit.
Step 4: Additionally, it may be necessary to test the Body Control Module (BCM) for functionality. The BCM controls various electrical functions in the vehicle, including the wiper park sense circuit. Testing the BCM will help identify if it is the source of the problem.
Step 5: Seek professional assistance if needed to accurately diagnose and resolve the issue. If you are unsure about any of the troubleshooting steps or do not have the necessary tools, it is best to consult a professional who can provide expert guidance.
Step 6: Properly addressing the B1446 code will prevent further damage or malfunctions. By following the troubleshooting steps and resolving the underlying issue, you can ensure that the wiper park sense circuit functions correctly and avoid any potential problems in the future.
What are the Common Diagnosis Mistakes
Common diagnosis mistakes can occur when troubleshooting the B1446 code, which can lead to delays in resolving the underlying issue. To avoid these mistakes and ensure an efficient diagnosis process, it is important to consider the following tips:
- Check the wiring harness and connectors: Make sure to visually inspect the related wiring harness and connectors for any signs of damage, such as fraying or corrosion.
- Perform thorough testing: It is not enough to simply replace components. Conduct proper diagnostic tests to avoid misdiagnosis and save time.
- Consider other potential causes: While the listed possible causes are a good starting point, it is essential to also consider other factors that may contribute to the B1446 code.
What is the Repair Cost
The repair cost for a B1446 code varies based on factors like location, vehicle make and model, and needed repairs. Labor costs typically range from $75 to $150 per hour with an average diagnosis time of 1.0 hour. Additional costs may apply for parts and repairs.
Seeking professional assistance for accurate diagnosis and timely repair is recommended to prevent further damage or malfunctions.
Can I drive safely with this code?
