C1431 — Damper LR Circuit Short To Battery

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

About C1431

C1431 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.

When C1431 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

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.

C1431 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 C1431 fault code indicates the suspension control module has detected a short to battery voltage on the left rear (LR) electronic damper control circuit. Electronically controlled dampers use solenoid valves to vary internal fluid restriction in real time, adjusting ride compliance based on inputs from suspension position sensors, accelerometers, and the stability control system. This code is specifically set when the module detects battery voltage on the damper control circuit when it should be off, indicating the control wire is shorted directly to a battery feed. When this code is activ...
