What is C04E5?
Diagnostic Trouble Code (DTC) C04E5 relates to the anti-lock braking system (ABS) and indicates a communication issue between the ABS module and the vehicle's control modules. When this code appears, it typically means the ABS system is not functioning correctly, which can lead to reduced braking performance and a potential safety hazard. The error can stem from a variety of issues including wiring faults, faulty wheel speed sensors, or a malfunctioning ABS control module. In simpler terms, if your vehicle detects this code, it is suggesting that the ABS system may not engage when needed, especially during hard braking or slippery conditions. It's crucial to address this issue promptly to maintain safe driving conditions. Vehicles commonly affected by this code include the 2015-2019 Ford Edge and similar models within the Ford lineup. Ignoring this code can lead to severe consequences, including increased stopping distances and compromised vehicle stability. Therefore, if you see code C04E5, it’s a good idea to have your vehicle inspected by a professional technician who can diagnose the issue accurately and perform the necessary repairs.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C04E5 is present:
- The ABS warning light illuminates on the dashboard, indicating that the anti-lock braking system may not be functioning properly.
- Drivers may experience longer stopping distances during emergency braking situations due to the compromised ABS.
- An unusual pulsating sensation in the brake pedal can occur when applying brakes, suggesting the ABS is trying to engage without proper communication.
- The brake system may feel less responsive, leading to concerns about overall vehicle safety and control.
- In some cases, the vehicle may enter a limp mode, limiting acceleration and performance until the issue is resolved.
Possible Causes
Most common causes of C04E5 (ordered by frequency):
- A wiring fault between the ABS module and other control units is the most common cause, with a likelihood of about 60%. Damaged or corroded wires can interrupt communication.
- Faulty wheel speed sensors can lead to incorrect readings, making the ABS system unable to function properly. This issue has a 25% likelihood.
- A malfunctioning ABS control module, while less common, can also cause C04E5 to trigger. Regular inspections can help prevent module failure.
- A less common but serious issue could involve a software glitch in the ABS module, requiring a software update from the manufacturer.
- In rare instances, physical damage to the ABS unit itself can cause communication failures, necessitating replacement.

Diagnostic Steps
Professional C04E5 Diagnosis Process
Follow these systematic steps to accurately diagnose C04E5. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Perform an initial visual inspection
Step 1: Perform an initial visual inspection. Look for damaged wiring, loose connections, or corrosion around the ABS unit and wheel speed sensors (5-10 minutes).
Step 2: Step 2: Use an OBD2 scanner, like the GeekOBD APP, to retrieve the C04E5 code along with any other related codes and freeze frame data (10-15 minutes)
Step 2: Use an OBD2 scanner, like the GeekOBD APP, to retrieve the C04E5 code along with any other related codes and freeze frame data (10-15 minutes). This data will help understand the context of the fault.
Step 3: Step 3: Conduct component testing using a multimeter to check voltage and resistance at the ABS module and wheel speed sensors (20-30 minutes)
Step 3: Conduct component testing using a multimeter to check voltage and resistance at the ABS module and wheel speed sensors (20-30 minutes).
Step 4: Step 4: After repairs, perform a system function test to verify proper operation of the ABS system and clear any codes (10-15 minutes)
Step 4: After repairs, perform a system function test to verify proper operation of the ABS system and clear any codes (10-15 minutes).
