The C1130 code indicates a problem with the right rear height sensor circuit in certain Nissan vehicles. This code typically arises when the ABS (Anti-lock Braking System) module detects that the height sensor is providing readings outside of the expected range. Understanding this issue is crucial for vehicle owners and technicians to ensure proper functionality of the vehicle's suspension and braking systems.

What Causes the C1130 Code?

The C1130 code can stem from various issues, including:

  • Faulty Right Rear Height Sensor: The sensor itself may be malfunctioning, leading to incorrect readings.

  • Wiring Issues: Damaged or corroded wiring between the height sensor and the ABS module can cause communication failures.

  • Control Module Faults: Problems with the ABS control module may prevent it from processing signals accurately.

  • Calibration Issues: If the height sensor is not properly calibrated after repairs or replacements, it may report out-of-range values.

Symptoms of C1130 Code

When a vehicle registers a C1130 code, several symptoms may manifest:

  • ABS Warning Light: The ABS light may illuminate on the dashboard, indicating a fault in the braking system.

  • Suspension Issues: Drivers might experience abnormal ride height or handling characteristics due to incorrect suspension adjustments.

  • Traction Control Malfunctions: The vehicle's traction control system may become less effective or non-functional.

Troubleshooting Steps

To address the C1130 code effectively, follow these troubleshooting steps:

1. Scan for Additional Codes: Use an OBD-II scanner to check for other codes that may provide insight into related issues.

2. Inspect Wiring and Connectors: Examine the wiring harness and connectors associated with the right rear height sensor for signs of damage or corrosion.

3. Test the Height Sensor: Measure the output voltage from the height sensor while adjusting the suspension to ensure it operates within specified parameters.

4. Check Control Module Functionality: Ensure that the ABS control module is functioning correctly and can communicate with other modules in the vehicle.

5. Calibration: If any components have been replaced, ensure that they are calibrated according to manufacturer specifications.

Common Fixes for C1130 Code

Addressing a C1130 code often involves several corrective actions:

  • Replace Faulty Sensor: If testing reveals that the height sensor is defective, replace it with a new one.

  • Repair Wiring Issues: Fix any damaged wiring or connectors to restore proper communication between components.

  • Recalibrate System: After replacing sensors or making significant repairs, recalibrate the system as necessary to ensure accurate readings.
