C1A67 (96-28) — Forward Looking Sensor Performance / Communication Fault

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

About C1A67

C1A67 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 C1A67 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour; and a sensor-related fault — the reported value from the named sensor is out of spec.

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.

C1A67 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 Forward Looking Sensor module, commonly the radar sensor used for adaptive cruise control and collision mitigation systems, continuously performs internal diagnostics and exchanges data with other control modules over the CAN network. DTC C1A67 is set when the module detects a performance or communication related fault, such as invalid or implausible sensor data, internal processing errors, or abnormal message timing or content on the network. This condition indicates the forward looking sensor cannot reliably determine object detection or distance, resulting in suspension of related drive...
