Feature 1Application: CAS test platform is compatible with multiple system modules, including CAS1, CAS2, CAS3, CAS3+, CAS3++, replacement for E chassis all models. 2Function: CAS programmer test platform can quickly check if the CAS module and key are working, no need to connect the car, easy to use. 3LED Light On: After the power is turned on, the LED light of the CAS test platform is always on, indicating that the CPU FLASH data is lost. It is recommended that you write the FLASH data of the models in the same year. 4LED Light Off: After the power is turned on, the LED light of the CAS test platform is off, indicating that the CPU FLASH data is locked caused by the unstable programmer when writing data, the EEPROM data needs to be edited. 5Durable Material: Auto key programmer platform is made of premium ABS material, high temperature resistant, sturdy and durable, long service life.Item Type:CAS Test PlatformMaterial: ABSFunction: Quickly check if CAS and keys are working, no need to connect the carTheCAS test platform helps you find out where the fault lies:Connect theCAS test platform to the CAS, and after the power is turned on, whether the LED lights are on or not helps to determine where the fault is.1. After the power is turned on, the LED light of the CAS test platform is always on, indicating that the CPU FLASH data is lost. It is recommended that you write the FLASH data of anothermodel in the same year.2. After the power is turned on, the LED light of the CAS test platform does not light up, indicating that the programmer is unstable when writing data, and the CPU FLASH data is locked, and the EEPROM data needs to be edited.3. When the CAS3 is broken during programming, the car cannot be started. Use theCAS test platform to connect the CAS. After the power is turned on, the LED lights up to indicate that the FLASH data is lost, and the EEPROM data is lost and locked.Applicable Models: Replacement for E chassis all modelsMatching System Modules: CAS1, CAS2, CAS3, CAS3+, CAS3++ .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x CAS Test Platform1 x Chip1 x Line
