Understanding the Service Electronic Braking System Message

If you encounter an intermittent “service electronic braking system” message on your 2018 Ram 2500, accompanied by a chime and occasional illumination of the ABS light, it’s essential to understand the potential causes and troubleshooting steps.

Possible Causes

• Malfunctioning speed sensors: Speed sensors monitor wheel speed and provide vital information to the electronic braking system. A faulty sensor can disrupt the system’s operation, triggering the warning message.
• Loose or damaged wiring connections: Loose or damaged wiring connections can interfere with the communication between the various components of the electronic braking system, resulting in the error message.

Troubleshooting the Issue

To troubleshoot the issue, follow these steps:

1. Inspect Speed Sensors and Wiring Connections

• Inspect the speed sensors located on each wheel hub for any signs of damage or wear.
• Check the wiring connections to the speed sensors to ensure they are secure and free from damage.
• Use a wiring diagram to locate and inspect all relevant wiring connections between the speed sensors and the electronic braking system module.

2. Scan for Diagnostic Trouble Codes (DTCs)

• Using an OBD-II scanner, scan your vehicle for DTCs. These codes can provide valuable insights into specific issues or malfunctions within the electronic braking system.
• If any DTCs are detected, research their meaning and potential causes to guide further troubleshooting.

Additional Considerations

• The intermittent nature of the message suggests a loose connection or sensor malfunction that may not always trigger a DTC.
• If the ABS light remains illuminated or you experience any changes in braking performance, seek immediate attention from a qualified mechanic or dealership.
• A thorough inspection by a professional will help pinpoint the root cause of the issue and ensure a safe and reliable braking system.
