What does engine code C121C mean?

The engine code C121C signifies a problem related to the ABS Pump Motor. This code usually indicates that there is a malfunction in the pump motor circuit, which could be caused by electrical issues or a faulty motor. To fix this issue, follow these steps:

1. Check for loose or corroded connections: Inspect the wiring harness and connectors associated with the ABS pump motor. Ensure that all connections are secure and free from corrosion. If any issues are found, repair or replace the affected components.

2. Test the ABS pump motor: Using a multimeter, measure the resistance of the pump motor. If it does not fall within the specified range, the motor may be faulty and needs to be replaced.

3. Inspect the ABS control module: The ABS control module could be causing the trouble code. Check for any visible signs of damage or corrosion on the module. If necessary, replace the control module.

4. Clear the trouble code: Once you have addressed the underlying issue, use an OBD-II scanner to clear the C121C trouble code from the engine control unit (ECU). This will reset the ABS system and allow for any further diagnostic procedures, if needed.

5. Test drive the vehicle: Take the vehicle for a test drive to verify if the issue has been resolved. If the ABS light and the trouble code do not reappear, then the problem has been successfully fixed.

Remember, if you are not confident in performing these tasks yourself, it is always advisable to seek assistance from a qualified mechanic.

What does the code C121C mean on a Dodge Magnum?

The code C121C on a Dodge Magnum indicates a problem with the steering angle sensor. This sensor is responsible for providing data on the position and movement of the steering wheel. Here’s how you can fix this issue:

Then, turn the ignition switch to the «ON» position without starting the engine. Slowly turn the steering wheel all the way to the left and then all the way to the right. Finally, center the steering wheel and turn off the ignition.
