About C1424

C1424 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 C1424 is stored, the module has detected an open (broken or disconnected) electrical path 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.

C1424 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 C1424 fault code indicates the suspension control module has detected an open circuit on the left front (LF) electronic damper control circuit. Electronically controlled dampers use solenoid valves to vary internal fluid restriction in real time. The module energises the damper coil to command the damping characteristic, then monitors current flow as feedback. This code is specifically set when the damper coil fails to conduct current when commanded, indicating either an open winding inside the damper solenoid or an open in the wiring between the module and the damper. When this code is ac...
