2022-2024 Honda Civic EPS Sticking and Slipping TSB

Owners of 2022-2024 Honda Civic vehicles may notice that their steering wheel does not automatically return to center, particularly when driving at highway speeds. This condition, described as Honda Civic EPS sticking and slipping, is addressed by Honda Service Bulletin 24-095, which supersedes the previous bulletin 24-095 dated July 25, 2024, and is now in Version 2. This bulletin provides technicians with a corrective action to resolve the issue.

Symptoms

The primary symptom reported by customers is that the "steering wheel does not automatically return to center" while driving, especially at highway speeds. This indicates a problem with the Electric Power Steering (EPS) system, specifically related to the Honda Civic EPS sticking or slipping.

What's the Problem?

The root cause of the Honda Civic EPS sticking and slipping issue lies within the EPS gearbox assembly. The corrective action involves redistributing grease to the worm gear and replacing the end cap, spring, and spring seat within this assembly. This procedure aims to restore the steering wheel's proper return-to-center function.

Important Warnings for Technicians and Owners

Honda has outlined several critical warnings within Service Bulletin 24-095 to ensure proper repair and prevent further damage:

• Do not use a screwdriver or metal tool to pry the EPS motor cover, as this can cause damage. A plastic trim tool should be used instead.
• Do not add any additional grease beyond what is specified during the repair process.
• Do not use brake cleaner to clean the EPS motor cover.
• Do not remove the steering gearbox from the subframe during the initial disassembly steps; only remove the steering gearbox/subframe assembly as a unit.
• Take appropriate steps to ensure no debris enters the EPS gearbox during the repair.

Repair Procedure Summary

The repair outlined in Honda Service Bulletin 24-095 involves a detailed process to address the Honda Civic EPS sticking issue. Here's a summary of the steps a Honda technician will follow:

1. The steering gearbox/subframe assembly is removed from the vehicle. Specific instructions are provided for both standard Civic models and Type R variants for this removal.
2. The heat shield is removed to access the EPS gearbox.
3. The area around the black cover on the EPS gearbox is thoroughly cleaned to prevent contamination.
4. The steering motor black cover is carefully removed using a plastic trim tool, ensuring no damage to the O-ring or housing.
5. The original O-ring is removed and discarded, and the cover is cleaned of any grease or contamination.
6. Grease within the worm gear area is carefully packed and redistributed to ensure proper lubrication, with a small amount saved for later steps.
7. A new end cap, spring, and spring seat are assembled with the saved grease.
8. The exposed sealant around the EPS gearbox end cap is cleaned, and the end cap is removed using a 10 mm hex socket bit.
9. The old spring and spring seat are removed from the EPS gearbox using a magnet tool and immediately discarded.
10. The new spring seat, spring, and end cap assembly are installed into the EPS gearbox. Hondabond sealant is applied to the exposed threads of the end cap.
11. The end cap is torqued to 12 N·m (9 lb-ft), and any excess sealant is wiped away.
12. All parts are reinstalled in reverse order of removal, including the steering motor black cover, which is torqued to 8 N·m (6 lb-ft).
13. The steering wheel is turned full left and full right to ensure smooth operation.
