ES300-LOWK Posted September 11, 2007 Share Posted September 11, 2007 Hello everyone. I'm new to this club and forum and this is my first post. I own a 1998 ES300 (since new) with currently just over 30K. Obviously, I don't drive it much and it stays in the garage most of the time. I run it regularly to get things to flow and the battery to charge. However, after a long 2+ month vacation over the summer, the battery died completely. I managed to have it recharged (trickle charge) at the local auto parts store, where it checked out OK, with good voltage and no dead cells. Unfortunately, during the removal and replacement process, the alarm went off a few times. Now, the car starts OK and the battery seems to have plenty of power but: [*]None of the dash, radio, auto A/C, etc. equipment and respective digital displays/gauges and lights work. [*]Power windows and locks do not work. [*]Remote lock/unlock/alarm does not work. [*]Shifter will not disengage from Park unless I override it mechanically with the console mounted button. [*]Who knows what else doesn't work ... I've read on the Internet that this may be due to the triggering of the alarm and the computer going into "theft mode" or maybe because of the computer losing power for too long and needing to be reset. Does anyone have any idea what may have happened and how to address this problem? Is this something I could do on my own somehow, or I'm I stuck with a trip to the dealer or, worse yet, to my "friendly" local (rip-off) Japanese auto care "expert"? Any information will help. Thank you. Quote Link to comment Share on other sites More sharing options...
Pete Zaria Posted September 11, 2007 Share Posted September 11, 2007 Before going much farther I'd try just leaving the battery unplugged overnight and trying again. This has solved several computer-related problems for me in the past. Other than that, for an issue like this I think you'll probably need to consult an expert. Peace, Pete Zaria.

TinyHero1971 Posted September 11, 2007 Share Posted September 11, 2007 It does sound like unplugging the neg. battery cable and leaving overnight may be a good starting point as it will reset your ECU and hopefully clear the error code... Checked all related fuses? Quote Link to comment Share on other sites More sharing options...

Ive checked all related fuses and replaced a couple that were bad; but that didn't solve the problem. Unplugging the battery sounds like a good idea. I'll try that tonight and post the (hopefully successful) results. Thank you all so much for the replies and suggestions. Quote Link to comment Share on other sites More sharing options...
