Quick answer

For Hyundai vehicles covered by the cited MDPS service information, C2412 is identified as “Motor voltage supply error.” The verified procedure directs a technician to erase the DTC, inspect wiring and connectors between the MDPS ECU and motor, replace the MDPS ECU if the code returns, and replace the MDPS motor if the code returns again where applicable.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does C2412 mean?

For Hyundai vehicles covered by the cited MDPS service information, C2412 is identified as “Motor voltage supply error.” The verified procedure directs a technician to erase the DTC, inspect wiring and connectors between the MDPS ECU and motor, replace the MDPS ECU if the code returns, and replace the MDPS motor if the code returns again where applicable.

2. Technical explanation

The supplied official Hyundai service-bulletin evidence identifies C2412 as an MDPS/C-MDPS motor voltage-supply error. MDPS refers to the motor-driven power steering system. The evidence does not establish a vehicle-specific root cause from the code alone; diagnosis follows the bulletin flowchart and requires confirmation of whether the DTC returns after the specified checks and repair steps.

3. What system is affected?

Motor-Driven Power Steering (MDPS), including the MDPS ECU/power-pack assembly, steering motor, and wiring/connectors between the ECU and motor.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • A warning lamp illuminated with DTC(s) present is referenced by the Hyundai MDPS repair flowchart.
  • Other symptoms for C2412 are not yet established by verified evidence.

6. Possible causes

  • Motor voltage supply error in the MDPS system.
  • Wiring or connector condition between the MDPS ECU and motor.
  • MDPS ECU or power-pack assembly fault if the DTC returns after the specified initial checks.
  • MDPS motor fault if the DTC returns after ECU/power-pack replacement, where applicable.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis by a qualified Hyundai service facility or technician familiar with the MDPS system.
  • Provide the stored code and any warning-lamp information to the service facility.
  • Do not attempt electrical component replacement based on the code alone.

10. Step-by-step troubleshooting

  1. Using the specified Hyundai diagnostic process, erase the DTC first.
  2. Check wiring and connectors between the MDPS ECU and motor.
  3. If C2412 returns, the cited bulletins direct replacement of the MDPS ECU or power-pack assembly.
  4. If the DTC returns after that repair, replace the MDPS motor where applicable.

11. When to contact service

Service is appropriate because the verified Hyundai procedure calls for diagnostic checks and potentially replacement of MDPS electronic and motor components.

12. What the service center may check

  • Confirm C2412 using Hyundai-compatible diagnostic equipment.
  • Erase the DTC and determine whether it returns.
  • Inspect wiring and connectors between the MDPS ECU and motor.
  • Follow the applicable Hyundai MDPS repair flowchart for the vehicle configuration.

13. Possible repair or resolution

  • Replace the MDPS ECU or power-pack assembly if C2412 returns after the initial erase and wiring/connector check.
  • Replace the MDPS motor if the code returns after ECU/power-pack replacement, if applicable.
  • For the 2015–2017 Sonata R-MDPS flowchart cited in TSB 22-ST-001H, C2412 is grouped with power-pack-related codes and directs replacement of the power-pack assembly.
