Code U11CD Dodge Description
The U11CD diagnostic trouble code (DTC) for Dodge vehicles indicates that the vehicle's onboard computer has lost communication with both rear wheel speed sensors. Wheel speed sensors are crucial components of the vehicle's anti-lock braking system (ABS) and traction control system. These sensors provide real-time data on the speed of each wheel to the ABS module, allowing it to adjust braking pressure and prevent wheel lock-up during hard braking or slippery road conditions. When the computer loses communication with both rear wheel speed sensors, it can lead to a loss of ABS and traction control functionality, compromising the vehicle's safety and handling.
Common Causes of U11CD Dodge
- Damaged or corroded wiring connections to the rear wheel speed sensors
- Failed rear wheel speed sensors
- Malfunctioning ABS module
- Issues with the CAN communication network
- Water or debris intrusion into the wheel speed sensor connectors
Symptoms of U11CD Dodge
- Illumination of the ABS warning light on the dashboard
- Traction control system warning light may also illuminate
- Increased stopping distances during braking
- Tires may skid or lock up more easily on slippery surfaces
- Unusual noises coming from the ABS module or wheel areas
How to Fix U11CD Dodge
- Begin by visually inspecting the wiring harness and connectors for any signs of damage or corrosion. Repair or replace any damaged wiring as needed.
- Test the rear wheel speed sensors using a multimeter to check for proper resistance values. Replace any faulty sensors.
- Check the ABS module for proper operation and communication. If necessary, reprogram or replace the ABS module.
- Inspect the CAN communication network for any faults or disruptions. Repair any issues found.
- Clear the DTC from the vehicle's computer using a diagnostic scan tool and perform a test drive to ensure that the ABS and traction control systems are functioning correctly.
