C1711 – OBD-II DTC

OBD-II DTC C1711 – Left Front Sensor Circuit Short to Vbat

DTC C1711 meaning

DTC C1711 refers to a diagnostic trouble code indicating a short circuit in the left front sensor circuit, specifically a short to battery voltage (Vbat). This code is typically associated with the vehicle’s anti-lock braking system (ABS) or traction control system, which relies on various sensors to monitor wheel speed and other parameters. A short to Vbat suggests that the circuit is receiving an unintended voltage, which can lead to incorrect readings and potential system malfunctions.

DTC C1711 symptoms

Common symptoms associated with DTC C1711 may include:

• Illumination of the ABS warning light on the dashboard
• Loss of ABS functionality
• Increased stopping distances during braking
• Unusual behavior of the traction control system
• Potential activation of other warning lights related to braking or stability control

DTC C1711 causes

Several factors can lead to the occurrence of DTC C1711, including:

• Damaged or frayed wiring in the left front sensor circuit
• Corroded or loose electrical connectors
• Faulty left front wheel speed sensor
• Short circuit due to moisture intrusion or physical damage
• Issues with the ABS control module

DTC C1711 seriousness

The seriousness of DTC C1711 can vary, but it is generally considered a moderate to high priority issue. The malfunction of the ABS or traction control system can compromise vehicle safety, especially in slippery conditions. It is advisable to address this code promptly to ensure optimal braking performance and vehicle stability.

How to diagnose DTC C1711

To diagnose DTC C1711, follow these steps:

1. Use an OBD-II scanner to confirm the presence of DTC C1711.
2. Inspect the left front sensor wiring and connectors for any visible damage or corrosion.
3. Check the resistance of the left front wheel speed sensor to ensure it is within manufacturer specifications.
4. Test the voltage at the sensor connector to determine if there is a short to Vbat.
5. Examine the ABS control module for any faults or issues.

How to fix DTC C1711 step-by-step instructions

To fix DTC C1711, follow these steps:

1. Disconnect the vehicle’s battery to ensure safety while working on the electrical system.
2. Inspect and repair any damaged wiring or connectors in the left front sensor circuit.
3. If the left front wheel speed sensor is faulty, replace it with a new one.
4. Reconnect all connectors and ensure they are secure and free of corrosion.
5. Reconnect the battery and clear the DTC using an OBD-II scanner.
6. Test drive the vehicle to ensure the ABS and traction control systems are functioning correctly.

How to erase DTC C1711

To erase DTC C1711, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the 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.
5. Disconnect the scanner and turn off the ignition.
6. Start the vehicle and monitor for any reoccurrence of the DTC.
