ECU wakeup for OBD scanner
« on: January 22, 2019, 10:49:37 am »
My Mazda 6 2010 is totally locked down. Press the clutch i get red key and red start button. This happened before and a guy came out with a code reader and cleared the error codes and the car operated as normal. I have a code reader but i am not able to turn on the ignition as nothing happens. The guy i used before is on holiday and i need my car. I have tried a different mechanic but his Scanner only connects when the ignition is on the same as mine.
If i can wake the ECU up it will talk to the scanner etc. anybody any idea how to do this.

Pic and vid attached to show the issue.

Alternatively does anyone know of a OBD scanner that could wake the car up.

Most of the people fixed that by cleaning an earth connection or changing the key module. It was not something that went away with a restart. Maybe the "reset" has to do with replacing a low key battery.

Thanks for the info.
I have read a lot of posts regarding the corroded earth. I have checked the ones i can see. Does anyone know where the one under the wing is or should be. ie which side etc.
