The B1436 code indicates a problem with the Wiper Hi/Low Speed Relay Coil, as detected by the Body Control Module (BCM).
Symptoms may include the illumination of the Engine Light or Service Engine Soon Warning Light.
The code can be caused by a faulty relay coil, wiring issues, or a malfunctioning BCM.
To fix the issue, it is recommended to thoroughly inspect the relay coil, wiring harness, and connectors.
The diagnostic and repair costs may vary depending on the vehicle's make, model, and engine type.
What does it mean
The B1436 code indicates a malfunctioning Wiper Hi/Low Speed Relay Coil. Symptoms may include the engine light being ON or the Service Engine Soon Warning Light illuminating.
To address this issue, check the wiring harness and connectors for damage or poor connections. Promptly addressing the issue is important to prevent further damage or malfunction.
what are the symptoms
The symptoms of the B1436 code may include the engine light or the Service Engine Soon Warning Light turning on. However, these symptoms don't directly indicate how the code affects the wiper functionality. To understand this, we need to analyze the root cause of the code.
The code is usually triggered when the Wiper Hi/Low Speed Relay Coil doesn't meet the factory specifications. If not fixed, the B1436 code can have long-term effects like the wipers not working properly or working intermittently. This can be risky as it reduces visibility during bad weather conditions, endangering the driver and passengers.
Therefore, it's important to promptly address the B1436 code to ensure the wiper system functions efficiently.
What are the causes
One possible cause of the B1436 code is a faulty relay coil for the wiper's high and low speeds.
Other potential causes may include a problem with the wiring or a faulty body control module (BCM).
It is important to note that there may be other causes as well.
When diagnosing the B1436 code, it is crucial to avoid common mistakes such as not checking the wiring and connectors visually, not looking for damaged components, and not inspecting the connector pins for any issues.
What Tools are Needed to diagnose
To diagnose the B1436 code, technicians need specific tools. These tools are important for accurately identifying and fixing the underlying issue. Here are three common diagnostic tools that technicians may use:
- OBD-II Scanner: This tool connects to the car's onboard computer system and retrieves diagnostic trouble codes (DTCs). It provides valuable information about the specific problem causing the B1436 code.
- Multimeter: A multimeter is used to measure electrical voltage, current, and resistance. Technicians can use it to check the electrical connections of the wiper hi/low speed relay coil circuit and find any open or shorted circuits.
- Body Control Module (BCM) Programming Tool: In some cases, a BCM reset may be necessary to fix the B1436 code. A BCM programming tool allows technicians to reset the module and clear any stored codes.
How to fix Step by Step
Step 1: Carefully inspect the related wiring harness and connectors for any signs of damage or issues.
Step 2: Visually inspect the components and check for broken or corroded connector pins.
Step 3: Look for any damaged wiring in the wiper hi/low speed relay coil circuit.
Step 4: Conduct regular maintenance to prevent DTC B1436 and allow for early detection and resolution of any potential issues with the wiper system.
Step 5: Address any problems promptly to ensure the proper functioning of the wiper hi/low speed relay coil and prevent the occurrence of the B1436 code.
What are the Common Diagnosis Mistakes
Common diagnosis mistakes can occur when dealing with the B1436 code. One of the common mistakes is not thoroughly inspecting the wiring harness and connectors for any signs of damage or issues. This oversight can lead to missing the actual cause of the code, resulting in wasted time and unnecessary repairs.
To avoid this mistake, follow these troubleshooting steps for DTC B1436:
- Conduct a visual inspection of the wiring harness and connectors. Look for any signs of damage such as frayed wires, loose connections, or corrosion.
- Use a multimeter to check for continuity and proper voltage in the wiper hi/low speed relay coil circuit. This will help identify if there is an open or shorted circuit.
- Verify that the wiper hi/low speed relay coil is functioning correctly. Test its resistance and compare it to the factory specifications. A faulty relay coil can trigger the B1436 code.
What is the Repair Cost
The repair cost for a B1436 code varies depending on factors such as location, make, model, and engine type. Most auto repair shops charge between $75 and $150 per hour for labor. However, this cost does not include parts or materials.
It's important to obtain a detailed quote from a trusted repair shop before proceeding.
Can I drive safely with this code?
No, it is not safe to drive with the B1436 code. Ignoring this code can lead to safety hazards and further vehicle damage.
The B1436 code indicates an issue with the Wiper Hi/Low Speed Relay Coil, affecting wiper system operation and visibility. It may also indicate a problem with the Body Control Module.
Prompt repairs are crucial for safe driving.
Conclusion
In conclusion, the B1436 code indicates a deviation in the Wiper Hi/Low Speed Relay Coil detected by the Body Control Module. This can lead to the illumination of the Engine Light or Service Engine Soon Warning Light.
The code may be caused by a faulty relay coil, a wiring harness issue, or a poor electrical connection. It is important to diagnose and fix the issue to ensure proper functioning of the wiper system.
