1180 318 168 0 Battery voltage: the voltage measured by
ECU is out of the target range Battery voltage over limit Check alternator, regulator of alternator and if
necessary replace it, check wiring and
voltage of alternator
1181 318 168 1 Battery voltage: the voltage measured by
ECU is out of the target range Battery voltage below limit Check alternator, cabling, contact resistance,
safety fuses, too high load in energy
system, check battery and if necessary replace it
