How can I prevent C0593 from happening again?
Regular maintenance checks on your braking system, including inspections of wiring and connections, can help prevent issues leading to the C0593 code.
What is C0593?
DTC C0593 is a diagnostic trouble code that indicates a fault in the electronic brake control module (EBCM) communication within your vehicle's braking system. This code is particularly prevalent in 2015-2019 Chevrolet and GMC models, which rely heavily on electronic systems for safety and performance. When this code is triggered, it means that the EBCM is unable to communicate effectively with other modules, which can lead to issues in the vehicle's anti-lock braking system (ABS) and traction control features. Drivers may experience symptoms such as the ABS warning light illuminating on the dashboard, reduced braking performance, or even unexpected activation of the ABS during normal braking. If left unaddressed, a malfunctioning EBCM can compromise vehicle safety. Therefore, understanding and resolving the underlying issues related to DTC C0593 is crucial for maintaining optimal braking performance and overall vehicle safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0593 is present:
- The ABS warning light remains illuminated on the dashboard, indicating a potential braking system issue.
- Drivers may notice the brake pedal feels spongy or unresponsive, which can affect stopping distances.
- Unexpected activation of the ABS during normal braking, causing the brakes to pulse intermittently.
- Reduced traction control effectiveness, particularly during slippery conditions, leading to increased chances of skidding.
- In some instances, there may be diagnostic trouble codes related to other brake system components stored in the vehicle's memory.
Possible Causes
Most common causes of C0593 (ordered by frequency):
- The most common cause is a faulty electronic brake control module, which has a 60% likelihood of being the issue. This can occur due to electrical faults or damage to the module.
- Wiring issues such as frayed or corroded connections between the EBCM and other modules can also trigger this code, contributing to about 25% of cases.
- Secondarily, a malfunctioning wheel speed sensor can lead to communication failure, with a 10% likelihood. Regular maintenance and inspections can help prevent sensor issues.
- Less common but serious causes include software corruption in the EBCM, which may require a software update or reprogramming.
- In rare instances, external factors like water intrusion can damage the EBCM or its connectors, leading to communication failures.

Diagnostic Steps
Professional C0593 Diagnosis Process
Follow these systematic steps to accurately diagnose C0593. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Conduct an initial visual inspection
Step 1: Conduct an initial visual inspection. Check for damaged wiring, loose connections, or signs of corrosion on the EBCM and related harnesses (5-10 minutes).
Step 2: Step 2: Use an OBD2 scan tool, like the GeekOBD APP, to retrieve all diagnostic trouble codes and freeze frame data
Step 2: Use an OBD2 scan tool, like the GeekOBD APP, to retrieve all diagnostic trouble codes and freeze frame data. This helps understand the context of the fault (10-15 minutes).
Step 3: Step 3: Test the suspected components using a multimeter to check for proper voltage and ground signals
Step 3: Test the suspected components using a multimeter to check for proper voltage and ground signals. This should include the EBCM and wheel speed sensors (20-30 minutes).
Step 4: Step 4: Perform a system function test to verify that the EBCM operates correctly after repairs
Step 4: Perform a system function test to verify that the EBCM operates correctly after repairs. Clear any existing codes and monitor for reoccurrence (10-15 minutes).
Step 5: Step 5: Conduct a road test under various conditions to confirm the repair and ensure that all braking functions operate properly (15-20 minutes)
Step 5: Conduct a road test under various conditions to confirm the repair and ensure that all braking functions operate properly (15-20 minutes).
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
