The fault code 6144 in the AL (Active Steering) module refers to monitoring and self-locking issues within the system. Here’s some information about this fault:

Definition/Description: The fault code indicates that there are monitoring or self-locking problems detected in the active steering system. This means that the control module is unable to properly monitor or engage the self-locking feature, which is essential for the correct operation of the system.

Meaning: The active steering system is designed to provide variable steering assistance based on various driving conditions. It relies on continuous monitoring of steering inputs and wheel speed to adjust the steering effort accordingly. Additionally, the self-locking feature helps maintain stability and control during specific driving situations.

When fault code 6144 is present, it means that the control module has detected issues related to monitoring or self-locking, suggesting that the system may not be functioning as intended.

Causes: Several factors can contribute to this fault code, including:

1. Sensor malfunction: Faulty sensors responsible for monitoring steering inputs and wheel speed can disrupt the system’s monitoring and self-locking capabilities.
2. Wiring or connector issues: Damaged or loose wiring connections, as well as faulty connectors, can result in intermittent or inaccurate data transmission between the sensors and the control module.
3. Mechanical problems: Issues with the mechanical components of the active steering system, such as the motor or gear mechanism, can hinder proper monitoring and self-locking functionality.
4. Software or programming errors: An outdated or corrupted software program or incorrect programming can lead to monitoring and self-locking issues.

Symptoms: Symptoms associated with this fault code may include:

1. Malfunction indicator lamp (MIL) or check engine light illuminated on the instrument cluster.
2. Inconsistent or unpredictable steering assistance, where the level of assistance may vary unexpectedly.
3. Loss of the self-locking feature, potentially affecting stability during certain driving maneuvers.
4. Abnormal steering feel, such as increased effort or reduced responsiveness.

Diagnosis: To diagnose the exact cause of fault code 6144, the following steps may be taken:

1. Using a diagnostic scanner or software specific to the vehicle’s make and model to retrieve and interpret the fault code.
2. Conducting a visual inspection of the active steering system components, including wiring, connectors, and sensors, for any visible damage or loose connections.
3. Performing system tests and sensor readings using diagnostic equipment to identify any abnormalities or inconsistencies in data transmission.
4. Updating or reprogramming the control module software if necessary to ensure proper functionality.

Common Mistakes: Common mistakes when dealing with this fault code include:

1. Focusing solely on the control module without inspecting the sensors, wiring, and connectors for potential issues.
2. Neglecting to perform system tests and sensor readings to validate the accuracy and consistency of data transmission.

How serious is this? The severity of this fault code depends on the specific symptoms and the impact on the active steering system. Monitoring and self-locking problems can affect the stability and control of the vehicle during steering maneuvers. It is important to address this issue promptly to ensure safe and reliable operation of the steering system.

What repairs can fix the code? Possible repairs for this fault code may include:

1. Inspecting and repairing or replacing faulty sensors responsible for monitoring steering inputs and wheel speed.
2. Checking and repairing damaged or loose wiring connections, as well as replacing faulty connectors.
3. Repairing or replacing mechanical components of the active steering system, such as the motor or gear mechanism, if they are found to be defective.
4. Updating or reprogramming the control module software to the latest version or correcting any programming errors.

It’s important to note that these are general guidelines, and the exact diagnostic and repair steps may vary depending on the vehicle’s make, model, and year. It’s recommended to consult the vehicle’s service manual or seek assistance from a qualified technician for an accurate diagnosis and appropriate repairs.
