Code U0126 RAM Description
The U0126 diagnostic trouble code indicates that the vehicle's onboard computer system has lost communication with the Steering Angle Sensor Module. The Steering Angle Sensor (SAS) is a critical component that measures the steering wheel position and rate of turn. This information is used by various safety systems, such as stability control and traction control, to ensure the vehicle maintains proper handling and stability. When communication with the SAS module is lost, it can lead to a loss of crucial data that affects the performance of these safety systems.
Common Causes of U0126 RAM
- Faulty wiring or connectors leading to poor connections
- Malfunctioning SAS module or sensor
- Electrical interference from other components or systems
- Software issues or communication errors within the vehicle's network
- Physical damage to the SAS module or sensor from external factors
Symptoms of U0126 RAM
- Malfunction indicator light (MIL) or check engine light illuminated on the dashboard
- Loss of stability control and traction control functionality
- Erratic steering behavior or lack of responsiveness
- Possible ABS system failure or irregular braking performance
- Reduced fuel efficiency due to compromised system operation
How to Fix U0126 RAM
- Begin by diagnosing the specific cause of the communication failure using a diagnostic scanner to retrieve trouble codes and data.
- Inspect the wiring and connectors for any signs of damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the SAS module and sensor for proper functionality. Replace if found to be faulty.
- Clear the trouble codes and perform a system reset to ensure proper communication is restored.
- Conduct a road test to verify that the symptoms have been resolved and the systems are operating correctly.
Cost to Fix U0126 RAM

Frequently Asked Questions about U0126 RAM Code
1. What does the OBDII code U0126 mean for a RAM vehicle?
The U0126 code means the vehicle has lost communication with the Steering Angle Sensor (SAS) module, which is crucial for various safety and stability systems.
2. What are the common symptoms of the U0126 code in a RAM?
Symptoms may include the ABS or traction control light turning on, loss of stability control functionality, or erratic steering behavior.
3. What causes the U0126 code to appear in a RAM?
Common causes include a faulty Steering Angle Sensor module, damaged wiring or connectors, issues with the CAN bus network, or a failing power supply to the module.
4. Can I drive my RAM with the U0126 code active?
While the vehicle may still be drivable, it’s unsafe to do so as stability and traction control systems may not function properly.
5. How do I diagnose the U0126 code in a RAM?
Start by inspecting the wiring and connectors for damage or corrosion, then check the power supply and communication lines to the SAS module using a multimeter or scan tool.
6. How do I fix the U0126 code on my RAM?
Repairs may involve replacing the Steering Angle Sensor module, repairing damaged wiring, or addressing CAN bus communication issues.
7. Can a low battery cause the U0126 code in a RAM?
Yes, a low or failing battery can disrupt communication between modules and trigger the U0126 code.
8. Is the U0126 code related to other systems in my RAM vehicle?
Yes, the SAS module is integral to systems like ABS, traction control, and stability control, so these systems may also be affected.
9. How much does it cost to fix the U0126 code on a RAM?
Repair costs vary depending on the issue, but replacing the Steering Angle Sensor module typically ranges from $200 to $600, including parts and labor.
10. Can I reset the U0126 code without fixing the problem?
You can clear the code with a scan tool, but it will likely return if the root cause isn’t addressed.
