ged600 Posted June 26, 2022 Share Posted June 26, 2022 2013 Mondeo 2.0 diesel. Come to the car this morning engine malfunction on dashboard ignition on but won’t let it turn over. Fine last time I used it midweek! Im a member of recovery so they’ve been out their diagnosis is? They plugged into diagnostics and the machine won’t communicate with ECU Anyone else had this problem and what was the outcome please.

unofix Posted June 26, 2022 Share Posted June 26, 2022 First disconnect negative lead from battery and leave it off for ten minutes. Reconnect battery and measure voltage with a multimeter. Is it more than 12.6V ? Use FORScan software to read DTC codes, not a generic multi-purpose code reader. 1 Quote Link to comment Share on other sites More sharing options...

Thanks, the recovery guy disconnected the positive lead left for 5 minutes reconnected 12.2 on voltmeter. He said that’s fine? He tried two different code readers, neither connected to ecu? What’s forscan software? Quote Link to comment Share on other sites More sharing options...
unofix Posted June 26, 2022 Share Posted June 26, 2022 12.2 Volt is NOT fine !! The State Of Charge is extremely low, virtually at critical level. Charge the battery for at least 12 hours or longer if possible. You need a standing voltage of ideally 12.65V or more. Make sure to connect the battery charger with the positive lead directly to the battery terminal and the negative lead to the main chassis earth point NOT the battery negative. FORScan software will read Ford specific DTC's it is very close to the same software as used by the local Ford dealers.

I once used to naively assume that a 12 volt charge on a 12 volt battery was fine - this chart may be helpful: 2 2 Quote Link to comment Share on other sites More sharing options...

Well well the mechanic went to the car today after 3 days in the waiting area. The engine malfunction light gone car started first time. He disconnected battery, checked the ecu no fault codes? He states this has happened before with fords over his years as a mechanic. I’ll drive it as normal for now but may get rid if it starts with more faults or the same one!

Jimpster Posted June 30, 2022 Share Posted June 30, 2022 I note your location,where abouts in Lancashire i'm Blackburn and have Forscan and the leads, if you need. Its of the age to be solder or cluster issue can throw up a multitude of faults then disapear. Quote Link to comment Share on other sites More sharing options...
