C1288 — Pressure Transducer Main / Primary Input Circuit Failure

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

About C1288

C1288 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 C1288 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.

C1288 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 C1288 fault code indicates that the ABS or stability control module has detected a fault on the main or primary brake pressure transducer input circuit. The pressure transducer is typically mounted on the master cylinder or hydraulic control unit and converts hydraulic brake pressure into a 0V to 5V analog signal that the ABS module uses for stability control, electronic brake force distribution, hill hold, and panic brake assist. This code is set when the signal is out of expected range, missing, or fails a rationality check against pedal effort and brake light switch input. When this cod...
