C1281 — Lateral Accelerometer circuit Failure

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

About C1281

C1281 is a manufacturer-specific chassis diagnostic trouble code recorded for Ford vehicles. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1281 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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.

C1281 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 lateral accelerometer reports the sideways acceleration of the vehicle to the ABS or chassis control module as one of the primary inputs to the stability control system. It is a MEMS based sensor typically packaged with the yaw rate sensor in a combined sensor cluster mounted on the floor near the centre of gravity. DTC C1281 sets when the controlling module detects a complete loss of the lateral acceleration signal, an out of range value, or no communication from the sensor on its dedicated bus or analogue input. When this code is active, stability control, traction control, and roll miti...
