They are new version updated,the CPU 1L85D and 3L40K can work steadily.But I found a trouble,the EIS,ECU and ESL will renew passwork normally when you starting car,but the EIS equipped with 1L85D and 3L40K will never change the code.All S-series,E-series,C-series equipped with 9S12 have this problem. They are firsr gen EIS of W220,equipped with two Motorola chip:1D69J and 0D69J.As the use of CPU long aging,it will result in gateway running all the time can not fall asleep and data lost.If 1D69J and 0D69J are damaged,it hardly to find replacement,but to replace whole EIS by 2155450608 or 2155450808 Insert the key into EIS,turn the ignition normally,but can not start the car and remote malfunction.This situation most likely that the CPU 1J35D or 4J74Y data damaged.And this problem can be solved by modifying chip data or replacing the CPU.
Model 2155450408 EIS common fault and solution: The EIS models are frequently on again off again,include 2155450208,2155450408,2155450608.īased on past repair experience,it most likely caused by CPU instability.And this EIS trouble can be solved by replacing 1J35D and 4J74Y chip.
