What is C00E5?

The DTC C00E5 is a diagnostic trouble code indicating a problem within the vehicle’s powertrain control module (PCM) related to the electric parking brake system. This code typically signals that the system is unable to properly engage or disengage the parking brake, which can lead to safety concerns when parking or driving. In practical terms, this means that the parking brake may not hold the vehicle in place when engaged, increasing the risk of rolling. Additionally, if the electric parking brake system fails, it may not allow the vehicle to start or could lead to other malfunctions. Affected vehicles include the 2015-2018 Honda Civic and similar models from other manufacturers that utilize electric parking brakes. Drivers may notice that the parking brake warning light remains illuminated on the dashboard, and the system may make unusual noises when engaged. If left unresolved, this issue can lead to more extensive repairs and increased costs over time, as the underlying electrical or mechanical issues worsen. It is essential to address this code promptly to ensure safe vehicle operation and prevent further damage.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C00E5 is present:

  • The parking brake warning light stays illuminated, indicating a fault in the system.
  • The electric parking brake does not engage or disengage properly, which can lead to safety risks.
  • Unusual noises are heard from the parking brake actuator during operation, suggesting a mechanical issue.
  • The vehicle may not start due to the parking brake system malfunctioning, impacting overall drivability.
  • Drivers may experience a decrease in vehicle stability when parked, as the parking brake fails to hold.

Possible Causes

Most common causes of C00E5 (ordered by frequency):

  1. The most common cause of the C00E5 code is a faulty electric parking brake actuator, with a likelihood of about 40%. This component is crucial for the system's operation and can fail due to wear and tear.
  2. A malfunctioning PCM is the second most common cause, affecting approximately 30% of cases. This can happen if the module itself has internal errors or if it has failed due to electrical surges or software issues.
  3. Wiring issues such as corroded connectors or damaged wiring harnesses account for about 20% of C00E5 occurrences. Regular visual inspections can help prevent this by identifying potential problems before they escalate.
  4. Less common, but serious causes include a stuck parking brake mechanism, which can lead to a complete inability to engage or disengage, affecting driving safety.
  5. In rare cases, a software glitch in the vehicle’s onboard computer can trigger this code, requiring a software update or reprogramming for resolution.
