ECU & Control Units

Electronic Control Units (ECUs) are the computing brains that manage vehicle subsystems — from battery management and motor control to body electronics, ADAS, and smart entry. This category covers SRS electronic control units, tire pressure monitoring modules, dashcam and panoramic imaging modules, thermal management integrated modules, body controllers (left, right, rear), multi-functional video controllers, DMS image modules, general controllers, MIC modules, smart entry controllers, suspension electronic control units, and cover actuators for BYD Atto 3, Dolphin, Sealion 7, and Denza D9. Replacement ECUs often require VIN coding or module pairing to enable full functionality — always source from suppliers that provide firmware compatibility documentation.
