The check engine light is on, the immobilizer light is flashing, there is no communication with the scan tool. The temperature gauge is inoperative. The car runs sluggishly, no acceleration. I am stuck with this problem because I change the ECM and the mechanic reprogrammed the module; everything was perfect in this moment, but when I turn the ignition off and I tried to turn it on again, the same problem occurred. I do not know what is wrong with my car. I know that it has to be an electrical problem, but I do not know where can I find it. I have read some comments posted in this forum and I found somebody with the same problem six years ago and the expert suggested check the cluster. I think that it is only the part under dashboard that I did not replace because I replaced the ECM and Multiplex. Please I need your help in this case
Note: I have already check the power in the plugs' cluster and it is okay. Also, I checked all fuses and relays and everything looks okay.
have the same problem?
