2022-2023 Honda Civic EPB Harness DTCs C1110-13 C1100-94

American Honda Motor Co., Inc. (AHM) has issued a communication indicating an active investigation into certain 2022-2023 Honda Civic models. The focus is on vehicles equipped with an automatic transmission that are experiencing specific Electronic Parking Brake (EPB) harness DTCs.

This initiative, titled "Request for Parts: 2022-2023 Civic EPB Harness DTCS (ACTION REQUIRED)", aims to gather more information and physical components from affected vehicles to better understand the root cause of the condition. Honda is explicitly requesting that dealers do not attempt repairs on these vehicles before contacting their Technical Information & Support (TIS) team.

Symptoms

Owners of affected 2022-2023 Honda Civic vehicles may experience a range of symptoms related to the Electronic Parking Brake (EPB) system. These often include the storage of specific diagnostic trouble codes (DTCs) within the vehicle's computer system.

In addition to stored fault codes, drivers might observe intermittent or persistent "warning lights on the MID" (Multi-Information Display). These warnings could be related to "brake system problems," "LKAS lights" (Lane Keeping Assist System), or "ACC lights" (Adaptive Cruise Control). If your Honda Civic EPB harness DTCs are present, these visual indicators will likely accompany them.

Fault Codes / DTCs

Honda's investigation is specifically targeting vehicles that have stored the following diagnostic trouble codes:

Code	Description
C1110-13	Left-Rear Electric Parking Brake Actuator Circuit Open
C1100-94	Electric Parking Brake Actuator Malfunction

These codes indicate issues with the left-rear electric parking brake actuator and its associated circuit, suggesting a potential problem with the EPB harness.

Important Warnings for Owners

It is crucial for owners to understand that Honda is currently in a data and parts collection phase for this issue. The manufacturer has provided explicit instructions to dealerships:

• Do not attempt any repairs or disassemble the harness and motor for this issue during the current visit.
• Previous replacements of the left rear brake assembly, left motor, and knuckle assembly are NOT accepted as qualifiers for this program.
• Vehicles that have been involved in a collision are also excluded from this specific information-gathering effort.

This means that if your 2022-2023 Honda Civic is exhibiting these symptoms and DTCs, your dealership is instructed to contact Honda's Technical Information & Support (TIS) before proceeding with any repair work. The goal is to collect parts from your vehicle to aid in understanding the underlying cause of the Honda Civic EPB harness DTCs.

Next Steps for Owners

If your 2022-2023 Honda Civic, equipped with an automatic transmission (excluding FHEV, Si, and Type R trims), is displaying the described symptoms or has the C1110-13 or C1100-94 DTCs, you should contact your authorized Honda dealership. Inform them about the specific warning lights and fault codes you've observed.

Your dealership will need to verify if your vehicle meets all the qualifiers for Honda's parts collection program. If it does, they will contact Honda Technical Information & Support (TIS) via email or phone to provide vehicle information and receive further instructions. Honda is offering a VISA gift card to technicians who successfully identify and report a qualifying vehicle that is accepted into the program, highlighting the importance of this data collection.
