About C1922

C1922 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 C1922 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.

C1922 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 C1922 is set when the module detects an open circuit in the VAPS solenoid actuator output, meaning current is not flowing through the solenoid at all. This is typically caused by a broken wire, a disconnected or corroded connector, or an internally open solenoid winding. When the code is set variable ...
