The B1217 code refers to a problem with the Rear Parking Assistant System (RPAS) in vehicles. Specifically, it indicates an issue with the Rear Right Sensor, which is responsible for detecting obstacles and calculating distances.
Some common causes of the code include a dirty or faulty sensor, an open or shorted sensor harness, or a poor electrical connection.
Symptoms of the B1217 code may include a malfunctioning parking assist system, an illuminated warning light on the dashboard, or the system not providing accurate distance calculations or obstacle detection.
To fix, the first step is to diagnose the issue by using a diagnostic scanner to retrieve the trouble codes and inspect the sensor, harness, and electrical connections. The sensor can be cleaned or replaced if necessary, and any faults in the harness or electrical connections should be repaired. Once the repairs are made, the code can be cleared from the system using the diagnostic scanner.
B1217 Rear Parking Assistant System (RPAS)
What does it mean
The B1217 code indicates a problem with the Rear Parking Assistant System (RPAS) and specifically the rear right sensor.
To diagnose the issue, visually inspect the wiring harness and connectors for damage, check for faulty sensors, and ensure there are no open or shorted circuits.
Seek professional help for accurate diagnosis and repair.
What are the symptoms
The B1217 code may cause the Engine Light or Service Engine Soon Warning Light to turn on. This warning light indicates a problem with the Rear Parking Assistant System (RPAS). There may be other symptoms associated with this code that are not mentioned here.
Here are three important points to know:
- The B1217 is related to the RPAS, which uses supersonic sensors to detect obstacles and calculate distances.
- The BCM receives signals from the sensors and alerts the driver through a buzzer or display. The warning levels are divided into three steps based on the distance from the obstacle.
- It is recommended to seek professional help to diagnose and fix. This requires a thorough inspection of the wiring harness, connectors, and components related to the RPAS system.
To prevent the code from appearing, regular maintenance and inspection of the RPAS system are crucial. Addressing any issues promptly and following recommended maintenance schedules can help prevent the code from coming back.
What are the causes
Possible causes:
- The Rear Right Sensor may be dirty.
- The Rear Right Sensor may be faulty.
- The Rear Right Sensor harness may be open or shorted.
- There may be a poor electrical connection in the Rear Right Sensor circuit.
- There could be other potential causes not listed.
Possible solutions to prevent the DTC B1217 code from happening again:
- Regularly clean the Rear Right Sensor to keep it free from dirt and debris.
- Check the Rear Right Sensor for any signs of damage or malfunction and replace it if necessary.
- Inspect the wiring harness and connectors for any signs of damage or poor connection. Repair or replace them as needed.
Common misconceptions about the DTC B1217 code and its implications:
- Some people may mistakenly think that the code only affects the Rear Right Sensor. However, it can also be caused by issues with the wiring or electrical connections.
- Some may think that the code is not a serious problem. However, it is important to address it because it can affect the functionality of the Rear Parking Assistant System and compromise safety.
What Tools are Needed to diagnose
To diagnose, professional technicians need specific diagnostic tools and equipment. These tools are necessary to accurately identify the cause of the code and make the required repairs.
Here are the tools that technicians may need:
- OBD-II scanner: This tool retrieves the code from the vehicle’s onboard computer system. It allows technicians to access diagnostic trouble codes, freeze frame data, and live sensor data.
- Multimeter: A multimeter is used to test the electrical circuits and components associated with the Rear Parking Assistant System (RPAS). It helps technicians identify any open circuits, shorts, or other electrical issues.
- Supersonic sensor tester: This specialized tool performs a sensor test for the code. It helps technicians determine the functionality of the Rear Right Sensor and verify if it is dirty, faulty, or experiencing poor electrical connections.
How to fix Step by Step
Step 1: Begin by troubleshooting the potential causes of the B1217 code.
Step 2: Conduct a thorough inspection of the vehicle’s wiring harness, connectors, and components.
Step 3: Visually inspect the wiring harness and connectors for any damage, such as broken or corroded pins.
Step 4: Check for any damaged components that may be causing the issue.
Step 5: Look for any signs of a poor electrical connection in the Rear Right Sensor circuit.
Step 6: Seek professional assistance if necessary to accurately diagnose and fix the issue.
Step 7: To prevent future occurrences of the code, conduct regular maintenance and inspections of the vehicle’s RPAS system.
Step 8: This will help ensure that any potential issues are detected and addressed promptly.
What are the Common Diagnosis Mistakes
One common mistake when diagnosing the code is not paying attention to potential issues with the wiring harness and connectors. This can result in incorrect diagnosis and unnecessary repairs.
To avoid common diagnostic errors and misunderstandings about the B1217, it is important to consider the following:
- Failure to visually inspect the related wiring harness and connectors: thoroughly examining them can help identify loose connections, damaged wires, or corrosion that may be causing the code.
- Neglecting to check for damaged components: faulty sensors or other parts can also trigger the B1217 code, so it is crucial to inspect them for any signs of damage or malfunction.
- Ignoring the possibility of poor electrical connections: inadequate electrical connections can disrupt communication between the sensors and the BCM, resulting in the code. It is important to check for loose or corroded connector pins.
What is the Repair Cost
The cost of repairing the B1217 code varies based on location, vehicle make and model, and engine type. Labor rates range from $75 to $150 per hour. Additional costs may apply for specific repairs and part replacements.
Regularly maintaining the rear parking assistant system can help prevent the code and reduce repair costs. Avoiding aftermarket modifications is also important.
Can I drive safely with this code?
Driving safely with the B1217 code is not recommended. This code indicates a fault in the Rear Parking Assistant System (RPAS), specifically the rear right sensor.
Ignoring the code can lead to reduced safety while parking or maneuvering the vehicle. Seek professional assistance to diagnose and repair the issue promptly.
Wrapping Up
The B1217 code is related to the Rear Parking Assistant System (RPAS) and indicates an issue with the Rear Right Sensor. This code can be triggered by various causes, including sensor malfunctions, wiring issues, or poor electrical connections.
It is important to address this code promptly to ensure the proper functioning of the RPAS and to avoid potential accidents or damage. Diagnosing and fixing the DTC B1217 may require specific tools and should be done following the appropriate step-by-step process.
