Check

8

Using a diode test lamp, check the electrical system for voltage between the positive line of the on-board electrical system battery (G1) and the disconnected ground line (6)

Model 207
with code B03 (ECO start/stop function)
Model 212
with code B03 (ECO start/stop function)
Model 212
with code ME04 (Mild hybrid drive)
Model 218
with code B03 (ECO start/stop function)
except code 4U7 (Start/stop voltage dip protector)

If the diode test lamp lights up, the on-board electrical system is still active because of a defect in the electrical system. In this case:



Disconnect ground line from additional battery for ECO start/stop function.
