About C1926

C1926 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 C1926 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.

C1926 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 uses a solenoid actuator, controlled by the power steering control module, to vary steering assist with vehicle speed. The return circuit provides the ground return path that completes the solenoid current loop. DTC C1926 is set when the control module detects an open circuit in the VAPS solenoid actuator return circuit, meaning current cannot flow through the solenoid because the return path is broken or has excessively high resistance. The solenoid regulates hydraulic pressure to the steering gear, providing more assist at low speed for parkin...
