COMBI Instrument cluster power supply: Cause
The fault memory entry does not indicate a defect in the instrument cluster or in the power supply of the instrument cluster, rather only disconnection of the power supply of the instrument cluster by the JBE: Reset or shutdown of terminal 30F. Reset or cutoff of terminal 30F is due to a fault in the vehicle: too many wakings with terminal R Off, closed-circuit current fault, sleeping inhibited, reaching the starting capability limit.
