The present invention provides a method for controlling an ink cartridge chip, the ink cartridge chip and an ink cartridge. The ink cartridge chip comprises an interface unit and a control unit, wherein the interface unit is connected to an image forming apparatus and used for receiving a light control instruction sent by the image forming apparatus; the light control instruction includes a light-on instruction used for indicating the illumination of a light-emitting unit on the ink cartridge chip; and the control unit is used for controlling whether to execute the light control instruction according to the state of the ink cartridge chip when the interface unit receives the light control instruction, and updating the state of the ink cartridge chip according to the light control instruction. The present invention also provides a corresponding control method and an ink cartridge. Therefore, the rate of false alarm of the image forming apparatus during the position detection of ink cartridges can be reduced.
