B1260 – OBD-II DTC

OBD-II DTC B1260 – Solar Radiation Sensor Circuit Short To Battery

DTC B1260 meaning

DTC B1260 refers to a diagnostic trouble code indicating a short circuit in the solar radiation sensor circuit, which is typically related to the vehicle’s climate control system. The solar radiation sensor measures the intensity of sunlight and helps the vehicle’s climate control system adjust the temperature and airflow accordingly. A short to battery condition suggests that there is an unintended connection between the sensor circuit and the battery voltage, leading to incorrect readings or system malfunctions.

DTC B1260 symptoms

Common symptoms associated with DTC B1260 may include:

• Inconsistent or incorrect climate control operation
• Malfunctioning automatic temperature control
• Warning lights illuminated on the dashboard
• Increased cabin temperature or discomfort

DTC B1260 causes

The causes of DTC B1260 can vary, but typical reasons include:

• Faulty solar radiation sensor
• Wiring issues, such as frayed or damaged wires
• Corrosion or poor connections in the sensor circuit
• Short circuit due to moisture intrusion or physical damage
• Faulty climate control module

DTC B1260 seriousness

DTC B1260 is considered a moderate issue. While it may not prevent the vehicle from operating, it can lead to discomfort due to improper climate control. Additionally, if left unaddressed, it may cause further damage to the climate control system or related components.

How to diagnose DTC B1260

To diagnose DTC B1260, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the DTC.
2. Inspect the solar radiation sensor and its wiring for visible damage or corrosion.
3. Check the sensor’s voltage and ground connections using a multimeter.
4. Test the solar radiation sensor for proper operation according to manufacturer specifications.
5. Examine the climate control module for any related fault codes or issues.

How to fix DTC B1260 step-by-step instructions

To fix DTC B1260, 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 solar radiation sensor circuit.
3. If the solar radiation sensor is faulty, replace it with a new one.
4. Reconnect the battery and clear the DTC using an OBD-II scanner.
5. Test drive the vehicle to ensure the issue is resolved and the DTC does not reappear.

How to erase DTC B1260

To erase DTC B1260, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
