So it has been a while since I was last on the board. Family, work, and winter have prioritized time and my '06 has been sitting since October. I last fired it up about a month ago. I tried to do this again today, but the battery was dead.
I pulled the terminals, set the battery on the charger, got everything up to spec and the moment I reconnected the terminals, the horn starts honking. Ok, this must be the immobilizer. I pulled the 25amp EFI fuse and replaced it with a new one. Same issue. I pulled the horn fuse to get a moment to analyze, now the secondary buzzer is raising the alarm.
I'm running out of daylight and it's getting cold again. Should I cobble together an immobilizer bypass circuit, or am I looking at the wrong issue? I was under the impression that the known immobilizer fault would not honk the horn. The experience of anyone who has gone through a similar situation would be appreciated.
Clearly there is a short or fault somewhere because the battery was drained to 7 volts and it was new in the late summer. I will chase that down once the horn problem is solved.
