ECM Clearing Codes WITHOUT scan tool even being hooked up.
I have a 2013 Cadillac ATS 2.0 Turbo AWD that is setting code P06DE, however that is not what I'm trying to address for now. My problem is the ECM is randomly clearing the code , freeze frame and monitors without being commanded. This is a new ECM and it was doing that same thing with the old one. I want to address this problem before I tackle the oil issue. I cannot find any info anywhere about this issue. Thanks
Each system requires at least one, and sometimes several, diagnostic tests. The results of these tests are reported by a diagnostic trouble code (DTC). A system monitor is complete when either all of the DTCs comprising the monitor have Run and Passed, or any one of the DTCs comprising the monitor have illuminated the malfunction indicator lamp (MIL) . Once all of the tests are completed, the I/M System Status display will indicate YES in the Completed column.For example, when the HO2S Heater Monitor indicates YES, either all of the oxygen sensor heater tests have passed or one of the tests has illuminated the MIL. If the vehicle has four heated oxygen sensors, either all four heater circuit tests have passed or one of the heater circuit tests has illuminated the MIL. The I/M System Status will indicate NO under the Completed column when any of the required tests for that system have not run. The following is a list of conditions that would set the I/M System Status indicator to NO:
The vehicle is new from the factory and has not yet been driven through the necessary drive conditions to complete the tests.
The battery has been disconnected or discharged below operating voltage.
The control module power or ground has been interrupted.
The control module has been reprogrammed.
The control module DTCs have been cleared as part of a service procedure.
