U11C2 OBD2 Code: Lost Communication with Steering Angle Sensor (Jeep Patriot 2016)

The dreaded U11c2 Obd2 Code For A Jeep Patriot 2016 often signals a problem with the steering angle sensor (SAS). This sensor plays a vital role in your vehicle’s stability control systems, so understanding this code and its implications is crucial. This article will delve into the u11c2 code, its common causes, diagnostic procedures, and potential solutions, empowering you to address this issue effectively.

Understanding the U11C2 OBD2 Code

The u11c2 obd2 code specifically indicates “Lost Communication with Steering Angle Sensor.” This means the vehicle’s electronic control unit (ECU) is not receiving the necessary data from the SAS. For a 2016 Jeep Patriot, this can affect various systems, including Electronic Stability Control (ESC), Anti-lock Braking System (ABS), and even the power steering. Ignoring this code can lead to compromised vehicle handling and safety.

Common Causes of the U11C2 Code in a 2016 Jeep Patriot

Several factors can contribute to a u11c2 code in your Jeep Patriot. These range from simple wiring issues to more complex sensor malfunctions.

Wiring Problems: Damaged, corroded, or loose wiring connections between the SAS and the ECU are a frequent culprit. Rodents chewing on wires are also a surprisingly common issue.
Faulty Steering Angle Sensor: The sensor itself can fail due to internal damage, wear and tear, or exposure to the elements.
Clock Spring Issues: The clock spring, located within the steering wheel assembly, allows the electrical connections to rotate with the steering wheel. A damaged clock spring can interrupt communication.
Steering Column Control Module (SCCM) Problems: In some cases, a malfunctioning SCCM can contribute to communication loss with the SAS.
Low Battery Voltage: A weak battery can sometimes disrupt communication between modules, including the SAS and the ECU.

Diagnosing the U11C2 Code

Proper diagnosis is crucial to pinpoint the root cause of the u11c2 code. Here’s a step-by-step approach:

Retrieve the Code: Use an OBD2 scanner to confirm the u11c2 code and check for any other related codes.
Inspect Wiring: Visually examine the wiring harness connected to the SAS for any signs of damage, corrosion, or loose connections.
Check Battery Voltage: Ensure the battery is fully charged and maintains a stable voltage.
Test the Steering Angle Sensor: Use a multimeter or specialized diagnostic tools to test the sensor’s resistance and output signal.
Inspect the Clock Spring: Check the clock spring for any signs of damage or binding.
Diagnose the SCCM: If the previous steps haven’t revealed the problem, a more advanced diagnostic scan might be necessary to check the SCCM.

Solutions for the U11C2 Code

Once the cause is identified, the appropriate solution can be implemented.

Repair or Replace Wiring: Repair or replace any damaged or corroded wiring. Secure loose connections.
Replace the Steering Angle Sensor: If the sensor is faulty, replacement is usually the most effective solution.
Replace the Clock Spring: A damaged clock spring will need to be replaced.
Address SCCM Issues: Depending on the specific problem, the SCCM might require repair or replacement.
Charge or Replace the Battery: A weak or failing battery should be charged or replaced as needed.
