Code C1459 Description
The diagnostic trouble code C1459 refers to an Adaptive Mode Switch Circuit Failure. This code typically indicates a problem within the adaptive mode switch circuit, which is a component of the vehicle's transmission system. The adaptive mode switch is responsible for adjusting the transmission shift points based on driving conditions and driver input. When this circuit fails, it can lead to issues with the transmission's performance, potentially causing erratic shifting, poor acceleration, and overall drivability problems.
Common Causes of C1459
- Faulty adaptive mode switch
- Wiring or connector issues in the circuit
- ECM malfunction
- Transmission control module (TCM) failure
- Electrical problems such as short circuits or corrosion
Symptoms of C1459
- Erratic shifting behavior
- Delayed or harsh shifting
- Poor acceleration
- Reduced fuel efficiency
- Illumination of the Check Engine Light
How to Fix C1459
- Diagnose the issue by using a scan tool to retrieve the trouble codes and perform a thorough inspection of the adaptive mode switch circuit.
- Check the wiring and connectors for any damage or corrosion, repairing or replacing as necessary.
- Test the adaptive mode switch for proper operation and replace if faulty.
- Clear the trouble codes and reset the ECM to relearn the transmission adaptation.
- Test drive the vehicle to ensure the issue is resolved and the transmission operates correctly.
Cost to Fix C1459
The typical repair costs for a C1459 code can vary depending on the specific cause of the issue and the labor rates at the repair shop. On average, the cost of parts for this repair can range from $100 to $300, while labor costs can range from $100 to $200. Overall, the total repair cost for addressing an adaptive mode switch circuit failure is typically between $200 and $500. However, it's important to note that these estimates are approximate, and actual costs may vary based on various factors.
