Modern vehicles rely heavily on electronic control units (ECUs) to manage critical systems, with faults often presenting as warning lights, poor drivability, or system malfunctions. At Harmac Automotive, we carry out precise diagnostics to accurately identify ECU and module-related issues, ensuring faults are properly repaired rather than simply cleared.
We provide the latest comprehensive in-house module and software programming, offering a cost-effective alternative to main dealer programming across a wide range of makes and models. Our services include ECU, TCM, BCM, and ABS programming, key coding, immobiliser coding and removal, replacement key programming, and stolen key deactivation. We also carry out software modifications, DTC removals, module repairs, and where possible module replacements and cloning. Our capabilities extend to repairing corrupted or “bricked” modules, including common faults. All work is performed using advanced, constantly updated equipment to ensure accuracy and reliability.
In many cases, programming can be completed with modules supplied to us, allowing for fast turnaround times without the need for the vehicle on-site. We also offer ECU remapping both on and off the vehicle, including returning vehicles to standard software to assist in fault finding, as well as Stage 1 remaps where required. By completing all programming, repairs, and module services in-house, we deliver efficient, dependable solutions while helping reduce the cost of unnecessary replacements. Trade enquiries are welcome.
