1、Application: CAS test platform is compatible with multiple system modules, including CAS1, CAS2, CAS3, CAS3+, CAS3++, replacement for E chassis all models. 2、Function: CAS programmer test platform can quickly check if the CAS module and key are working, no need to connect the car, easy to use. 3、LED 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. 4、LED 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. 5、Durable Material: Auto key programmer platform is made of premium ABS material, high temperature resistant, sturdy and durable, long service life. Item Type: CAS Test Platform Material: ABS Function: Quickly check if CAS and keys are working, no need to connect the car The CAS test platform helps you find out where the fault lies: Connect the CAS 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 another model 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 the CAS 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 models Matching System Modules: CAS1, CAS2, CAS3, CAS3+, CAS3++ 1 x CAS Test Platform 1 x Chip 1 x Line
