Hi All I have a scenic that had 'injection fault' on dashboard and non start/no crank.
Scan showed d113 minimum voltage reached. Found battery virtually flat. Charged it and the tested it(bat121)50% start capacity. So replaced it cleared errors and started ok. Checked for current drain 0.07amps. Checked charging Bat121......ok and loaded ok.
2 days later car back the same....thoughts are alternator smart charge fault possibly.(no drain). So testing this systems can some one confirm if this is correct. Scope on wire of 2 pin plug at alternator PWM in relation to electrical load will show ecu control. Wire to battery from 2 pin plug is just voltage sensing? Amps clamp on main alt cable for output.
Is that it for testing?? Anyone seen this before with Renault?
