ismailmiller 1st Gear June 13, 2019 Share June 13, 2019 (edited) Hi guys,My car had this error while driving on MCE on tuesday, I stopped my car at the side of the exp to restart the car but still the same. I decided to continue the journey as it did not affect my car driving. Finally reached my destination and open up the hood. Found one of the battery wire connector slightly loosen and tightened the screw. Tried to restart the car and problem went away but came back after a minute later. I decided to ignore it.It hasnt come back since and I drove the car the past two days without this error. Any thoughts what could cause this?

Watwheels Supersonic June 14, 2019 Share June 14, 2019 The error code will still be stored in the ecu even though the warning light is off now. Only with an obd diagnostic tool you will be able to retrieve the error code to decipher what triggered the code. FYI nowadays all car computers work this way. It's only when the issue isnt resolved then the warning light keeps coming back. A diagnostic test from any workshop will cost you...I dunno how much since I dunno what car you are driving. Investing some money on an obd diagnostic tool you will still need some mechanic experience to decipher the code. Sometimes the error code is not that straight forward. It could be other parts that trigger the code. LoL... If I'm not wrong the code should be telling you some connection error. 1 Link to post Share on other sites More sharing options...
