2022-2024 Honda Civic EPS Light On U3000-49 TSB 24-006

Symptoms

Owners of 2022-2024 Honda Civic models may notice the "Electric Power Steering (EPS) System Indicator" illuminated on their instrument panel. This warning indicates a potential issue with the vehicle's power steering system.

Fault Codes / DTCs

When the Electric Power Steering (EPS) System Indicator light appears, technicians may find the following diagnostic trouble code (DTC):

• U3000-49: This code specifically points to a low battery voltage condition affecting the EPS system.

Diagnosis / Trigger Conditions

The root cause of the Honda Civic EPS light U3000-49 is often a degraded 12-volt battery. If the battery voltage drops too low during an ignition cycle, the EPS system can detect this low voltage condition. This interruption can cause the steering angle calculation to stop, triggering the DTC U3000-49 and illuminating the EPS warning light.

Important Warnings for Owners

• Software Updates: Unnecessary or incorrect repairs resulting from a failure to update the diagnostic and reprogramming software are not covered under warranty. Ensure your dealer confirms all software is up to date before any repairs.
• Battery Voltage During Service: If your vehicle's 12-volt battery drops below 10 volts during a software update, the programming status bar may not display correctly, or the Honda ECU Reprogramming application might show an error message. This highlights the importance of maintaining proper battery voltage during service.
• VCI Device: Honda explicitly states, "Do not use the MongoosePRO VCI for this service bulletin as it is not an American Honda approved device." This is a critical instruction for technicians to ensure proper repair.

Repair Procedure Summary

To address the Honda Civic EPS light U3000-49, Honda Service Bulletin 24-006 outlines a specific repair process. The primary step involves updating the EPS Unit software to the latest version. This update must be performed using the Honda ECU Reprogramming application.

After the software update, technicians must perform two calibration procedures. First, the VSA Sensor Neutral Position Memorization procedure is completed, ensuring the steering wheel is straight and the vehicle is on a flat, level surface. This involves using the i-HDS diagnostic tool to select "ADJUSTMENT" from the ABS/TCS/VSA menu and then "ALL SENSOR." Second, an All Sensor Learn procedure is performed through the i-HDS, navigating to the SYSTEM SELECTION MENU, then ABS/VSA, ADJUSTMENT, and finally selecting "ALL SENSOR" and confirming with "YES."

Required Tools or Parts

Technicians will need specific software and equipment to perform this service:

• Diagnostic Software:
  • i-HDS Software Version 1.008.033 or later
  • HDS Software Version 3.105.028 or later
  • Honda ECU Reprograming 3.6.0.0
• Battery Support: A fully charged jumper battery pack or a Midtronics GR8-110P AST in Power Supply Mode, or a Midtronics DCA-8000 Dynamic Diagnostic Charging System in Reflash Mode, must be connected to the vehicle's 12-volt battery throughout the procedure to maintain stable voltage.
• Program IDs (or later):
  • EX, EX-L, LX, Sport, Touring: 39990-T39-A140
  • EX, EX-L, LX, Sport, Sport Touring: 39990-T43-J030
  • SI: 39990-T38-A050
  • Type R: 39990-T60-J040
