The C101C Dodge Code is an indication of a Right Front Wheel Speed Sensor Signal Erratic Performance.
This code is set when the Anti-Lock Brake System (ABS) Module detects an intermittently missing signal, an erratic wheel speed signal during acceleration, or a wheel speed signal that is different from other wheels.
This article will explore the causes, symptoms, and costs associated with this code, as well as provide diagnostic and repair tips.
Key Takeaways
- The C101C Dodge Code indicates erratic performance of the Right Front Wheel Speed Sensor.
- Possible causes of this code include mismatched tire air pressure, faulty wheel speed sensor, open or shorted sensor harness, poor electrical connection, or faulty ABS module.
- Diagnostic steps involve visual inspection of wiring harness and connectors, checking for damaged components and corroded connection pins.
- Regular maintenance is essential for keeping a vehicle in good condition and avoiding costly repairs or breakdowns.
Understanding the C101C Dodge Code
The C101C Dodge Code is an indication of the Right Front Wheel Speed Sensor signal exhibiting erratic performance. It is triggered when the ABS module senses a missing or erratic wheel speed signal while the vehicle is moving at a speed of over 25 mph.
This could be caused by mismatched tire air pressure, a faulty wheel speed sensor, an open or shorted wheel speed sensor harness, a poor electrical connection, or a faulty ABS module. To diagnose the code, a visual inspection of the related wiring harness and connectors should be done, as well as checking for damaged components and corroded connection pins.
Additionally, it is recommended to consult Dodge’s Factory Service Bulletin for this code. The cost of diagnosis and labor can vary depending on the make and model of the vehicle. Symptoms of this code include the ABS warning light being on, and the engine light being on.
Diagnosing the Right Front Wheel Speed Sensor
Diagnosis of the Right Front Wheel Speed Sensor is necessary when it exhibits an erratic performance. The ABS Module monitors the Right Front Wheel Speed Sensor and sets the OBDII code when the signal is intermittently missing or is different from other wheels while the vehicle speed is above 25 mph (40 km/h).
A visual inspection of the related wiring harness and connectors is the first step in diagnosing the issue. Also, check for damaged components, broken, bent, pushed out, or corroded connector pins. If Dodge has issued a Factory Service Bulletin for the C101C code, it should be consulted.
Lastly, it is important to note that the diagnosis time and labor rates can vary depending on the make and model of the vehicle.
Resolving the Erratic Performance
Resolving the erratic performance of the Anti-Lock Brake System (ABS) Module requires careful diagnosis of the related wiring harness and connectors.
Visually inspect the wiring and check for damaged components, such as broken, bent, pushed out or corroded connector pins.
It is important to check whether the tire air pressure is mismatched or the Right Front Wheel Speed Sensor is faulty.
If the issue is not resolved with the above steps, consult the Dodge service bulletin for the C101C code. This will provide more detailed instructions on how to resolve the issue.
Moreover, it is important to remember that diagnosis time and labor rates may vary depending on the make and model of the vehicle, and engine type.
