C1924 — VAPS Solenoid Actuator Output Circuit Short To Ground

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

About C1924

C1924 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 C1924 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.

C1924 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 Variable Assist Power Steering (VAPS) system varies steering effort with vehicle speed by controlling hydraulic assist through an electrically operated solenoid actuator. The control module drives current through the VAPS solenoid, giving more assist at low speed and less at higher speed. DTC C1924 is set when the module detects the VAPS solenoid actuator output circuit shorted to ground, meaning the output wire is grounded when it should not be. This is commonly caused by chafed insulation contacting the chassis, a corroded connector, or an internal short to ground within the solenoid. Wh...
