C1497 – OBD-II DTC

OBD-II DTC C1497 – Traction Control Motor Potentiometer Circuit Short to Battery

DTC C1497 meaning

DTC C1497 refers to a diagnostic trouble code indicating a short circuit in the traction control motor potentiometer circuit to the battery. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various vehicle systems for faults. The traction control system relies on the potentiometer to provide feedback on the position of the throttle or brake, and a short to battery suggests an electrical fault that could affect the system’s performance.

DTC C1497 symptoms

Common symptoms associated with DTC C1497 may include:

• Illumination of the traction control warning light on the dashboard
• Reduced traction control functionality
• Increased wheel spin during acceleration
• Potential activation of the anti-lock braking system (ABS) warning light
• Erratic behavior of the traction control system

DTC C1497 causes

Several factors can lead to the triggering of DTC C1497, including:

• A short circuit in the wiring of the traction control motor potentiometer
• Faulty potentiometer itself
• Corroded or damaged connectors in the circuit
• Issues with the traction control module
• Electrical interference from other components

DTC C1497 seriousness

DTC C1497 is considered a moderate to serious issue. While the vehicle may still be operable, the traction control system’s reduced functionality can lead to decreased vehicle stability, especially in slippery conditions. It is advisable to address this code promptly to ensure safe driving conditions and to prevent further damage to the vehicle’s electrical system.

How to diagnose DTC C1497

To diagnose DTC C1497, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the C1497 code.
2. Inspect the wiring and connectors associated with the traction control motor potentiometer for any visible damage or corrosion.
3. Check the potentiometer’s resistance using a multimeter to ensure it operates within the manufacturer’s specifications.
4. Test the traction control module for proper function and communication with other vehicle systems.
5. Clear the code and perform a road test to see if the code reappears.

How to fix DTC C1497 step-by-step instructions

To fix DTC C1497, follow these step-by-step instructions:

1. Disconnect the vehicle’s battery to ensure safety while working on the electrical system.
2. Inspect and repair any damaged wiring or connectors related to the traction control motor potentiometer.
3. If the potentiometer is faulty, replace it with a new one that meets OEM specifications.
4. Reconnect all connectors and ensure they are secure and free of corrosion.
5. Reconnect the battery and use an OBD-II scanner to clear the DTC.
6. Perform a road test to verify that the traction control system is functioning correctly and that the code does not return.

How to erase DTC C1497

To erase DTC C1497, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the vehicle’s ignition without starting the engine.
3. Navigate to the “Erase Codes” or “Clear DTCs” option on the scanner.
4. Confirm the action to clear the trouble codes from the vehicle’s computer.
5. Disconnect the scanner and start the vehicle to ensure the code does not reappear.
