If your Range Rover displays “stability control not available,” it may be due to issues with the ABS system, steering angle sensor, or wheel speed sensors. These components play key roles in maintaining stability control. A professional diagnosis is recommended.
Great. Just what we needed. Time to grab our toolboxes and get to fixing this thing!
Let’s start with some basic signs and symptoms that you may encounter if your Range Rover is having stability control issues.
What models are affected?
- Land Rover Defender
- Range Rover Discovery
- Range Rover Evoque
- Range Rover Sport
- Range Rover Velar
- Range Rover Vogue
Signs and symptoms
The most obvious sign of a stability control system failure is the “Stability Control Not Available” message that pops up on your dashboard when you start your vehicle.
However, there are other symptoms that could indicate an issue with the system. For example, you may experience a noticeable decrease in acceleration and handling ability, especially when driving on rough terrain or in adverse weather conditions.
In some cases, you may also notice that your steering feels loose or unresponsive, and you may hear strange noises when turning or braking.
List of possible OBD codes
If you suspect that your Range Rover’s stability control system is failing, you can use an OBD (On-Board Diagnostics) scanner to check for any relevant codes.
Here are some of the most common codes that could indicate a problem with the stability control system:
- C1A28-Steering Torque Sensor Plausibility Failure
- U0401-Invalid Data Received from ECM/PCM A
- U0100- Lost Communication with ECM/PCM A
- U0127- Lost Communication with Ride Level Control Module
Several factors could contribute to a stability control failure in your Range Rover.
Here are some of the most common causes:
- Faulty Wheel Speed Sensors: These sensors are responsible for measuring the speed of each wheel and providing data to the stability control system. If one or more of them fail, the system may not function properly.
- Malfunctioning Steering Angle Sensor: This sensor measures the angle of the steering wheel and provides data to the stability control system. If it malfunctions, the system may not know how to properly adjust the car’s movements.
- Damaged Wiring: Problems with the electrical wiring that connects the various parts of the stability control system can cause issues. Sometimes, the wires get corroded or damaged, and this can cause the system to fail.
- Low Battery Voltage: If the battery is low, the stability control system may not have enough power to function properly. This is especially true during startup when the power requirements are higher than normal.
Can it be fixed without a mechanic?
The answer to this question is maybe. Although many issues with the stability control system will require a mechanic’s attention, there are a few things you can check and fix yourself.
It’s important to note, however, that if you’re not comfortable working on your car, it’s always best to take it to a professional.
Parts you’ll need to fix it
If you need to replace any parts to fix your Range Rover’s stability control system, here’s what you’ll need:
- Wheel Speed Sensor
- Steering Angle Sensor
- Wiring Harness
Tools you’ll need to fix it
Here are the tools you’ll need to fix your Range Rover’s stability control system:
- OBD Scanner
- Socket Wrench
- Wire Stripper
- Wire Connectors
- Electrical Tape
How to fix it
Let’s get started on fixing that stability control issue! Here are the steps you should follow:
- Use an OBD Scanner to diagnose the exact cause of the stability control problem.
- Check all the electrical connections to make sure that they are secure and free of corrosion.
- Inspect the wheel speed sensors and steering angle sensors for any damage or signs of wear. If any are found, replace them.
- Check the battery to ensure that it is fully charged and functioning correctly.
- If necessary, replace any damaged wiring harnesses.
- Once all repairs are made, use the OBD scanner once more to clear any diagnostic trouble codes.
Potential alternative causes
While the aforementioned issues are the most common causes of stability control failure, there are a few other possibilities.
Some Range Rovers are known to have issues with their ABS system. This system works in conjunction with the stability control system to optimize vehicle operation according to road conditions directly related to the brake system.
If you begin experiencing trouble steering your vehicle, especially heavily, the problem may not be with the stability control system itself, but with the brake system, tandem works. In this scenario, I recommend taking your vehicle to a professional for further diagnosis.
What does it mean when the Range Rover displays the message “Stability Control Not Available” ?
This message typically indicates a fault or malfunction in the stability control system of the vehicle.
Why would the stability control system not be available in a Range Rover?
There can be various reasons for this, including sensor failures, electrical issues, software glitches, or other components related to the stability control system.
Is it safe to drive the vehicle when the stability control is not available?
It is generally recommended to exercise caution when driving without stability control, as this feature helps enhance vehicle stability and control. It’s best to have the issue diagnosed and repaired as soon as possible.
How important is the stability control system in my Range Rover?
The stability control system is a crucial aspect of the driving systems in your car. It helps prevent skidding and helps maintain the car’s steering when driving in slippery conditions or when taking hard corners. Failure to address stability control problems could lead to significant vehicle damage and safety issues.
In conclusion, if you’re encountering the “Stability Control Not Available” message on your Range Rover, you’ll want to diagnose and fix the issue as soon as possible. While some issues may require professional attention, there are steps you can take to fix the problem yourself.
Remember, safety is always the top priority. If you’re unsure or uncomfortable working on your vehicle, take it to a professional for repairs.
