What are the symptoms
The common symptoms of the B1220 code are an illuminated engine light and potential performance issues in the vehicle. Ignoring this code can have three possible effects:
- Reduced Performance: Ignoring the B1220 code can compromise the performance of your vehicle. The Recirculation Control Motor, which is monitored by the Climate Control Unit, plays a crucial role in maintaining optimal climate control functionality. Ignoring the code could result in reduced airflow and inefficient temperature regulation, affecting your overall comfort while driving.
- Damaged Climate Control Functionality: The B1220 code indicates that the Recirculation Control Motor does not meet factory specifications. Ignoring the code may lead to further damage to the climate control system, potentially resulting in a complete failure of the system. This could make it difficult to regulate the temperature inside the vehicle, especially during extreme weather conditions.
- Costly Repairs: Ignoring the B1220 code can have financial implications. If the issue is not addressed promptly, it could lead to more extensive damage to the climate control system, requiring costly repairs or even a full system replacement. It is recommended to seek professional assistance for accurate diagnosis and repair to prevent further damage and expenses.
What are the causes
Possible causes of the B1220 code include:
- A faulty Recirculation Control Motor
- A problem with the wiring
- A loose connection in the Recirculation Control Motor circuit
- A faulty Climate Control Unit
It’s important to note that there may be other potential causes as well.
To diagnose the B1220 code, diagnostic tools like a scan tool and a multimeter can be used.
Some people mistakenly believe that the Climate Control Unit is always to blame or that the issue is solely with the Recirculation Control Motor. However, a thorough diagnosis is needed to identify the exact problem.
It’s recommended to seek professional help for accurate diagnosis and repair to avoid affecting climate control functionality.
What Tools are Needed to diagnose
To diagnose the B1220 code, technicians need specific tools like a scan tool and a multimeter. These tools are necessary to identify the source of the problem and determine the appropriate action.
Here are the common tools used for diagnosing DTC B1220:
- Multimeter: This tool helps measure electrical values like voltage, resistance, and continuity. Technicians use it to check if the circuit is intact and find any damaged or shorted wires.
- OBD II scanner: This scanner retrieves and interprets diagnostic trouble codes from the vehicle’s computer system. It provides valuable information about the specific issue causing the B1220 code.
- Wiring diagram reference: Technicians use this reference to understand the electrical connections and components involved in the recirculation control motor circuit. It helps them trace the wiring and identify potential faults.
- Circuit tester: A circuit tester verifies the presence of voltage and tests the functionality of electrical components. It ensures that power is reaching the recirculation control motor and helps pinpoint any electrical issues.
How to fix Step by Step
Step 1: Start by visually inspecting the wiring harness and connectors related to the B1220 code for any damage. Look for broken, bent, pushed out, or corroded connector pins.
Step 2: If any components are found to be damaged, they should be replaced. Seek professional assistance if necessary for an accurate diagnosis and repair.
Step 3: Troubleshoot the Recirculation Control Motor by checking if it is faulty. This can be done using appropriate diagnostic tools and techniques.
Step 4: Check for an open or shorted Recirculation Control Motor harness. Inspect the wiring for any signs of damage or malfunction.
Step 5: Ensure there is a good electrical connection in the Recirculation Control Motor circuit. Check for loose or disconnected wires and reattach them if necessary.
Step 6: Perform regular maintenance and inspections of the climate control system to prevent the B1220 code from recurring in the future. This includes checking for any signs of wear or damage and addressing them promptly.
Step 7: Address any related codes or warning lights promptly to prevent further damage and ensure proper functionality of the climate control system.
Note: It is recommended to consult a professional for an accurate diagnosis and repair of the B1220 code.
What are the Common Diagnosis Mistakes
Common Diagnostic Mistakes in relation to the B1220 code can lead to incorrect assessments of the underlying issue and potential misdiagnosis of the Recirculation Control Motor malfunction. To avoid these errors, it is important to remember the following troubleshooting tips:
- Make sure to thoroughly inspect the wiring harness and connectors visually. This will help you identify any problems such as open circuits or poor electrical connections that may have been missed.
- Always check for damaged components, such as a faulty Climate Control Unit. Neglecting this step can lead to incorrectly attributing the problem to the Recirculation Control Motor.
- Don’t overlook broken, bent, pushed out, or corroded connector pins. These issues can cause intermittent electrical connections and contribute to the B1220 code.
What is the Repair Cost
The repair cost for resolving the B1220 code can vary depending on factors such as labor rates, location, and the vehicle’s make, model, and engine type. On average, labor rates range from $75 to $150 per hour. Additional repairs or parts replacement can increase the total cost.
It is recommended to compare quotes from local repair shops to find affordable options. Independent mechanics or smaller shops may offer more competitive prices.
Ensure the chosen repair option provides quality service and expertise in fixing the B1220 code.
