11. Real-World Example: Diagnosing a Faulty EPB

Can you provide a real-world example of diagnosing a faulty Electronic Parking Brake? Here’s a real-world example of diagnosing a faulty Electronic Parking Brake (EPB).

The Situation

A 2017 Ford Fusion arrived at the shop with an illuminated EPB warning indicator. The diagnostic scan revealed DTC C2005:74 stored in the ABS module, indicating that the clamp request from the ABS module was taking longer than 8 seconds to perform. This DTC applied specifically to the right rear actuator motor.

Initial Assessment

Symptoms: EPB warning light, DTC C2005:74.
Vehicle: 2017 Ford Fusion.
Initial Thought: Because there were no circuit DTCs, and the actuator motor was eventually applying, it was assumed that the wiring between the ABS module and the actuator motor was intact, with no shorts to ground, voltage, or each other. This DTC was performance-related, suggesting the ABS module was not satisfied with the EPB activation.

Diagnostic Steps

Visual Inspection:
- The rear brake pads were checked and found to be about 7mm thick, ruling out extremely worn brake pads as the cause.
Component Comparison:
- The actuator motors were removed from both rear calipers to compare the effort required to apply them.
- Turning the ball screw on both calipers revealed that significantly more torque was needed to extend the right-side caliper piston compared to the left-side.
Conclusion:
- The actuator motor was functioning, but the extra time needed to reach the end of its travel was causing the ABS module to register the performance DTC.

Solution

The right-side caliper was replaced due to its sluggish piston movement.
The DTC was cleared, and the EPB system was tested to ensure proper functionality.

Outcome

The EPB warning light was extinguished, and the system operated correctly after the caliper replacement.

Key Takeaways

Systematic Approach: A systematic approach involving visual inspection, component comparison, and diagnostic scan tool analysis was crucial in identifying the root cause.
Performance DTCs: Performance DTCs can indicate mechanical issues within the system, such as a sticking caliper.
Component Comparison: Comparing components can help identify subtle differences that may not be apparent through other diagnostic methods.
