A ECM is not reset by removing the battery terminal
That causes more problems in the CPU program and also looses any radio codes
ECM units are reset by the use of a scan tool
Take it to an accredited service shop , have the fault codes read to see exactly is causing the problem , then have the ECM reset using the scan tool
