Code C103D Chrysler Description
The C103D Chrysler code indicates that there is erratic performance in the rear wheel speed sensor signal. The wheel speed sensor is responsible for sending data to the vehicle's ABS (anti-lock braking system) and traction control system. When the sensor detects that a wheel is rotating at a different speed than the others, it sends a signal to the ABS module to adjust braking pressure accordingly, preventing wheel lock-up and loss of traction.
Common Causes of C103D Chrysler
- Damaged or corroded wiring leading to the rear wheel speed sensor
- Faulty rear wheel speed sensor
- Loose or corroded connectors at the sensor
- Issues with the ABS module receiving and interpreting sensor data correctly
Symptoms of C103D Chrysler
- ABS warning light illuminated on the dashboard
- Traction control light engaging unexpectedly
- Pulsating brake pedal during normal driving
- Increased stopping distance when braking
How to Fix C103D Chrysler
- Begin by diagnosing the specific cause of the erratic rear wheel speed sensor signal using a diagnostic scan tool.
- Inspect the wiring and connectors leading to the rear wheel speed sensor for any damage or corrosion. Repair or replace as necessary.
- Test the rear wheel speed sensor for proper operation and replace if faulty.
- Clear the diagnostic trouble codes from the vehicle's system and test drive to ensure the issue has been resolved.
- If the problem persists, further diagnosis of the ABS module may be required.
Cost to Fix C103D Chrysler
The typical repair costs for this issue can vary, but you can expect to pay between $150 and $300 for parts and labor. This estimate includes the cost of a new rear wheel speed sensor, any necessary wiring or connectors, and the labor involved in diagnosing and repairing the issue. Keep in mind that specific diagnosis time and labor rates at auto repair shops can vary, so it's best to contact local shops for a more accurate estimate.
