OBD-II DTC C1506 – Dynamic Stability Control Right Rear Valve Malfunction

DTC C1506 meaning

DTC C1506 refers to a malfunction in the Dynamic Stability Control (DSC) system, specifically indicating an issue with the right rear valve. The DSC system is designed to enhance vehicle stability by controlling wheel slip during acceleration and cornering. When the right rear valve fails to operate correctly, it can lead to compromised vehicle handling and safety.

DTC C1506 symptoms

Common symptoms associated with DTC C1506 may include:

• Illumination of the DSC warning light on the dashboard
• Reduced stability control functionality
• Increased wheel slip during acceleration
• Unusual handling characteristics, especially in slippery conditions
• Potential activation of the anti-lock braking system (ABS) warning light

DTC C1506 causes

Several factors can contribute to the occurrence of DTC C1506, including:

• Faulty right rear valve or actuator
