The 991 brought a fully revised chassis to the 911 lineage and embedded PASM more deeply into the car's electronic architecture than any generation before it. When you go to aftermarket coilovers on the 991, the PASM module expects a data stream it will no longer receive. The dash lights, the potential PSM interference, the persistent fault codes, they're all part of the same problem and they all go away with this kit.
This is a 991-specific solution from KW, designed to communicate with the PASM module through the correct signal protocol for this generation. It plugs into the factory harness without modification, keeps the module satisfied, and leaves your other electronics fully operational. The 991 drives the way you want it to without electronics getting in the way.
