Possible Causes of C1137 Code in Nissan
The C1137 code in Nissan indicates a problem with the RAS (Rear Active Steer) control unit circuit. This system is responsible for adjusting the rear wheels’ angle to improve handling and stability during cornering and high-speed driving. When the control unit circuit detects an issue, it triggers the C1137 code and illuminates the check engine light. Here are some possible causes of this code:
- Faulty RAS control unit: The most common cause of the C1137 code is a malfunctioning RAS control unit. This component may fail due to internal damage, corrosion, or electrical issues. A faulty control unit cannot communicate with other systems, leading to incorrect wheel angle adjustments.
- Wiring problems: The RAS control unit circuit relies on several wires and connectors to transmit signals and power. If any of these components are damaged, loose, or corroded, the circuit may fail, triggering the C1137 code. Wiring problems can occur due to exposure to moisture, heat, or physical damage.
- Failed rear steering angle sensor: The RAS control unit uses data from the rear steering angle sensor to determine the correct wheel angle adjustments. If this sensor fails or sends incorrect signals, the control unit may not function correctly, leading to the C1137 code.
- Defective rear steering actuator: The rear steering actuator is responsible for adjusting the rear wheels’ angle based on the control unit’s commands. If this component fails or malfunctions, the control unit may not be able to adjust the wheels correctly, leading to the C1137 code.
- Low battery voltage: The RAS control unit circuit requires a stable and sufficient power supply to function correctly. If the battery voltage is low or fluctuating, the control unit may not receive enough power to operate, leading to the C1137 code.
If you experience the C1137 code in your Nissan, it is essential to diagnose the problem correctly to avoid replacing unnecessary components. A qualified mechanic can use specialized tools and procedures to identify the root cause of the code and recommend the appropriate repairs.
