C1443 — Steering Phase A Circuit Short To Ground

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

About C1443

C1443 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 C1443 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.

C1443 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 C1443 fault code indicates the ABS or stability control module has detected a short to ground on the Phase A channel of the steering angle sensor circuit. The Phase A signal is one of two quadrature outputs that the steering angle sensor uses to report direction and rate of steering input to the stability control system. This code is specifically set when the module detects the Phase A signal pulled to or near chassis ground continuously rather than producing the expected square wave. When this code is active, stability control is typically disabled, the warning lamps illuminate, and elect...
