C1506 — Dynamic Stability Control Right Rear Valve Malfunction

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Generic

About C1506

C1506 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1506 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Dynamic Stability Control (DSC) system uses a hydraulic control unit containing electrically operated solenoid valves to modulate brake pressure at each wheel during ABS, traction control, and stability interventions. Code C1506 is set when the ABS/DSC control module detects an electrical fault in the right rear valve circuit, such as an open circuit, a short to earth or voltage, or a coil resistance reading outside the expected range during the module's continuous self monitoring. Because the valves are housed inside the hydraulic unit and driven directly by the module, this code most oft...
