The diagnostic trouble code E58507 indicates an issue with the ICM (Integrated Chassis Management) module’s interface related to the vehicle speed signal. The code specifically indicates that the signal received by the ICM from the vehicle speed sensor is considered invalid. Here’s more information about this code:

Definition/Description: E58507 is a fault code that is triggered when the ICM module receives an invalid or abnormal signal from the vehicle speed sensor. The ICM module is responsible for managing various chassis control systems, including traction control, stability control, and suspension control.

Meaning: The code suggests a problem with the communication between the ICM module and the vehicle speed sensor. The invalid signal received by the ICM module may indicate an issue with the sensor itself, a problem with the wiring or connectors between the sensor and the ICM module, or a fault within the ICM module.

Causes: Possible causes for this code may include:

1. Faulty vehicle speed sensor: The sensor that measures the vehicle speed may be malfunctioning or sending incorrect signals to the ICM module.
2. Wiring or connector issues: There may be damaged or loose wiring connections, or corroded connectors, between the vehicle speed sensor and the ICM module.
3. Faulty ICM module: The ICM module itself may have a fault that prevents it from interpreting the vehicle speed signal correctly.

Symptoms: Symptoms associated with this code may include:

1. Illumination of warning lights on the instrument cluster, such as the ABS (Anti-lock Braking System) or stability control warning light.
2. Malfunction or incorrect operation of chassis control systems, such as traction control or stability control.
3. Erratic or inaccurate speedometer readings.
4. Loss of cruise control functionality.

Diagnosis: To diagnose the exact cause of the invalid vehicle speed signal, a series of tests and inspections should be performed, including:

1. Using a diagnostic scanner to retrieve and interpret the E58507 code.
2. Checking for any additional related codes or warnings in other control modules.
3. Inspecting the wiring and connectors between the vehicle speed sensor and the ICM module for damage, loose connections, or corrosion.
4. Testing the vehicle speed sensor for proper operation using appropriate diagnostic tools.
5. Verifying the functionality of the ICM module and its ability to receive and interpret the vehicle speed signal.

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

1. Neglecting to check the wiring and connectors for faults before replacing the vehicle speed sensor or the ICM module.
2. Assuming the problem is solely related to one component without considering the entire system and its communication link.
3. Not performing a comprehensive inspection of all relevant components, including the vehicle speed sensor, wiring, connectors, and the ICM module.

How serious is this? The severity of this code depends on the specific vehicle and the systems affected by the invalid vehicle speed signal. It may lead to impaired operation of chassis control systems, such as traction control or stability control, and can affect the accuracy of speed-related functions.

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

1. Repairing or replacing damaged wiring or connectors between the vehicle speed sensor and the ICM module.
2. Replacing a faulty vehicle speed sensor if diagnosed as the cause of the invalid signal.
3. Replacing a faulty ICM module if diagnosed as the cause of the communication issue.

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.
