If the fault code is not current, it may be deleted. In this case, the battery voltage was too low over an extended period.Charge the battery, if
necessary.Note:This fault could result in consequential faults. You should therefore process this fault first and then erase the fault
memory.Question:Is the fault current in several control modules?
YES
Possible cause and remedy
- Battery voltage too low.Test battery.Charge battery, replace if necessary.
- If fault occurs again:Check alternator.Communication with ECU required
- The quiescent current is too high.Test quiescent current.
NO
Test prerequisite
- Fuse o.k.
- Fuse o.k.
Test sequence
- Ignition: OFF
- Measurement at component
- Measure direct voltage with multimeter between ground socket and socket
Specified value
- Voltage[11.0...14.5] V
Question
- Is the measurement value OK?
