Decoding the C1288 Ford Error
A diagnostic check for a Ford Focus or C-Max exhibiting this issue often points to a faulty “Brake Pressure sensor” or specifically reveals the C1288 error code. While mechanics frequently recommend replacing the entire ABS Pump Module, this can be an expensive solution. Rebuilding the ABS pump module offers a cost-effective alternative that addresses the root cause and reinforces the module to prevent future occurrences of the C1288 fault.
Recognizing the Symptoms
The C1288 Ford fault code is commonly accompanied by:
- Illuminated ESP/Traction Control Warning Light: A persistent warning light signals a potential issue with the Electronic Stability Program.
- Illuminated ABS Warning Light: Indicates a problem with the Anti-lock Braking System.

- Ford Focus (Mk II): Production years 2004-2011
- Ford C-Max (Mk I & Facelift): Production years 2005-2010
Part Numbers Associated with C1288 Ford Issues
Several part numbers are associated with the ABS modules in these Ford models. While a comprehensive list is extensive, some common ones include 6M5Y-2C405-AC, 6M5Y-2C405-AD, 8M51-2C405-CA, 8M51-2C405-AA, 8M51-2C405-EA, 6M5Y-2C405-AA, 3M51-2C405-HC, 8M51-2B373-AA, and 3M51-2C405-HA. These cover a range of ATE MK60 ABS ASC Pump modules.
Testing and Rebuilding the ABS Module
Reputable repair shops employ specialized Hardware-In-the-Loop testing rigs to diagnose ABS module issues under simulated real-world driving conditions. This comprehensive testing pinpoints the fault, enabling technicians to rebuild the unit with superior components compared to the original equipment manufacturer (OEM) parts.
Post-Rebuild Procedures
After a professional rebuild, the ABS module typically doesn’t require programming. Simply reinstall the module, bleed the brakes according to the manufacturer’s instructions, and the vehicle should be operational.
Bleeding the brakes is a crucial step after reinstalling a rebuilt ABS module.
Quality and Warranty
Reputable rebuilders often provide a lifetime warranty on their work, reflecting confidence in their repair process and the quality of the rebuilt components.
Conclusion: Addressing the C1288 Ford Issue
The C1288 Ford fault code can be effectively resolved by rebuilding the ABS module. This solution provides a cost-effective and reliable alternative to replacing the entire unit, ensuring long-term functionality and preventing recurring issues. By understanding the symptoms, affected vehicles, and repair options, Ford owners can confidently address this common problem.
