rameshbabu.n 6 Report post Posted December 9, 2012 (edited) I need some information on this specific technical issue. Seek your help and comments. Does the DDIS (Digital Drive Information System) / DDAS (Digital Drive Assist System) has it's own in-built, rechargeable, button battery/batteries ? This data is needed by me as my Xylo E8's DDAS is behaving funny now, for the last one week or so. The car's batter is perfect. No issues with that. No starting trouble and no other electrical issues. The Date/Time on the DDAS is getting reset whenever the engine is switched off. It is asking me to key in the date/time every time I start the engine. All the other parameters are OK. The fuel indicator, the mileage-to-empty, gear indicator, inside and outside temperature etc., are shown perfectly. Becuase these parameters are calculated on-the-fly whereas the date/time are `carried over' from the memory. So, I feel that this DDAS must have a rechargeable, button type of battery (one or more) built-in. What's your say on this ? Has any ACI'an faced similar problem/glitch ? And, how it was resolved ? I did not talk to any M&M Dealer or Service Personnel, so far. Anyway, I have to take my Xylo for it's annual servicing this month-end (max by mid-Jan'13). By then, I should have sufficient info/data on this. (oops ! there's a typo error in the title. Please read " it'w " as " it's ". Sorry for that) Edited December 9, 2012 by rameshbabu.n Quote Share this post Link to post Share on other sites
BHP-junkie 2 Report post Posted December 10, 2012 Hello rameshbabu.n, you can call the M&M service guys and visit them before your year end service. I am sure they will help you out in some way. Don't go for any part change or spare part without discussing it with M&M guys... Quote Share this post Link to post Share on other sites
CarCrazyASTL 16 Report post Posted December 10, 2012 By observing this, there must be small batteries! (like one in wrist watches & calculators) but only M&M service guys can tell you, how approch them! so it's better to call them & verify! Quote Share this post Link to post Share on other sites
librankur 39 Report post Posted December 11, 2012 Dear Rameshbabu From the way you put it ,it surely looks like an issue with the internal clock cell or some snap that does not let it charge .Never experienced such a thing before so canno pin point the trouble Was remembering you the other day when i was writing about the TPMS that been troubling me (what would you have said about these hyped features in cars that after a while become an eyesore) on another thread about car features and here you come up with a similar feature riddled / riden trouble.
