Well, one of those days...and the story goes like this:

1. Did change the air filter to do my 6k mils service and removed the battery to easily access the air filter box.
2. After finishing the air filter change, I reconnected the dam battery wrong, flipped the poles. It sparked around the relay/ cables area (right side by the right side panel). Also activation noise came from the ABS unit. I let the ABS idle for a while (while still not being aware that the battery was connected wrong.
3. Finally I recognized my mistake, disconnected the battery immediately, ABS noise was going away.
4. Turning the battery around reconnecting the battery correctly.
5 Checking the ignition and function by turning the key, System tries to boot up (Dial lights, fuel pump initiation, then all goes black again. Start won't work.
6. The Anti-theft system is also not giving the peeps, so it looks the intended initiation, system check can't finish.

Haven't checked the fuses in detail but it doesn't look that any of the wire insulation left any burn marks, etc...

Suggestions? Possible culprit, similar case of stupidity.

Thanks in advance
 
Hate to say it but the reverse polarity may have fried your ECU and dash. Also voltage regulator and anything else sensitive to polarity change.
 
Man, that sucks. Sorry for your luck, but please continue to update us on your progress. Contrary to what some say it can happen so easy it would be good for the next guy to know what to do. And again, sorry that your are the guinea pig.

I hope the fuses would have prevented that, I will check that today....fingers crossed.

Yes, I will post an update when I checked the fuses and cables. On the first look, there was no obvious damage or electric smells....but something is up.

Update: Yahhhhhhooooooo, I just blew a 40 and 7.5 fuse. Connected battery, enter service code 34534, and then 'Fire in the hole'. All good, got a free pass on this one.

EXCELLENT! Glad to see that the fuses worked like they are intended and that you don't seem to have caused any other harm.

It is good to be lucky. Fuses don't protect polarity shifts, only excess current, so it is a good thing they blew. You need diodes to protect polarity shifts which I don't see in the schematics.
