uvidim no necham sa prekvapit ci to po vymene CAS bude opravene 😀
ved to, ze "na nejakej"... s tym CAS budes musiet ist tak ci tak na bmw diag, aj ked to posielaju uz prisposobene na danne vozidlo, ale nejaka inicializacia/programovanie tam bude nutne.... ono cely ten energy/power management v bmw je dost komplexna a zlozita zalezitost a vyzaduje to prave taku diagnostiku (a aj cloveka k nej), co tomu rozumie... preto je idealne ist za niekym, co ma s tymyto autami skusenosti a aj prislusnu diag....navyse u e90 je aj viac variacii a odlisnosti podla vybavy a datumu vyroby vozidla..... Je k tomu v technnickych priruckach dost vela popisane, ale aj ked to clovek precita niekolkokrat dookola, stale tomu nemusi stopercentne rozumiet..... Zaujimave je ze dochadza k resetovaniu budikov.... tie by mali byt napajane z terminal 30, co je stale napatie z baterie.... avsak u niektorych modelov (od 09/2007 do 09/2009) je to inac, ten terminal 30 pre budiky je riadeny jednotkou JBE a dokonca je monitorovany ak je tam nejaky parazitny odber, takze v JBE by sa mali ulozit chyby, tak isto aj v budikoch.... a na zaklade toho sa daju spustit prislusne testovacie procedury (energy diagnosis).....
A tak isto mozno mas v aute IBS, co je dalsia podstatna vec a dalsie rozdiely.... ten moze tiez parazitovat a robit problemy s elektrikou celkovo.... a CAS moze byt ok, ale je tam odber, pretoze auto sa nevie uspat....
Zelam aby sa to vyriesilo vymenou cas, ved daj vediet ako to dopadlo, aj ked mne sa zda, ze to tym nemusi byt........
nieco z technickeho okienka:
Instrument cluster: power supply switched offSymptoms:- The time and date in the instrument cluster and in the Central Information Display are lost.
- The fault code memory entry ”instrument cluster: power supply switched off” is stored in the instrument cluster.
Cause:The fault code 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 KGM: reset or cut off terminal 30g‐f.Reset or cutoff of terminal 30g‐f 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.Procedure:If there is an impairment (e.g. time was lost; see above symptoms), the test module 'Energy diagnosis' helps in finding the cause of the problem in the vehicle energy system: run the test module.If the vehicle had a breakdown due to a flat battery despite the reset or cutoff of terminal 30g‐f, it is usually the case that the control units supplied via this terminal are not the likely cause.
