CEM- Central Electronic Module (Master ECU)
CEM-1F00 ECM software. Faulty signal​
ECM- Engine Control Module Petrol
ECM-223B Rear heated oxygen sensor (H02s) bank 1 signal
ECM-5110 Malfunction indicator lamp (MIL) CEM. Faulty Signal​

Any ideas? I know the cause of the ECM-223B because I have a cutout, what about the rest?
