2003 360 F1 Spider. Just changed out the right side fuel pump...no problems... took 45 mins. Everything works fine... Immobilized light is blinking... press the fob and it goes off. Car starts Perfectly, but the immobilized red light comes ack on... not blinking... a solid red. Am I having a senior moment and it was like this all the time... solid red when driving...just thought it was always off. No CEL's no nothing. Cut the power for 30 mins...same story. Appreciate input.
From what i have seen and read on the forum it means your siren battery is dead. Can you set the siren off? Sent from my SM-N910G using Tapatalk
Agreed it sounds like a siren battery, but it's such a coincidence... no red light before fuel pump change...red light after! Anyone else want to offer opinions?
Plug and play as long as you completely cut the power off, disconnect the old siren, replace with new siren and then connect the battery. Sent from my SM-N920V using Tapatalk
Please take note that you may experience issues if you cross reference to the Corvette part. There are several threads reporting that the cross referenced part though it beeps when arming an disarming, it doesn't "cry for help" when the alarm is triggered. I have one and it has this issue. The blinkers blink so you know the alarm system is tripped but no sound whatsoever. Consider yourself warned on this cross referenced part.
Just as others have stated, siren battery. When I first got my 360, the red light was on steady when the engine was running/driving. There also was no chirp when turning off the disabler. I had the car in the shop to get work done, and I asked them to check the siren and replace whatever is wrong with it. It was a dead battery, it was replaced, now the car chirps when turning the disabler off, and there is no red light at all when the car is running/driving.
There was a good thread a while back about wiring in a remote battery to the original alarm/siren box that was located near the brake master cylinder making it easy to get to and change. Way cheaper, and better, than replacing the expensive oem part.
That's a great solution but many times it's not possible because the failed battery leaks and destroys the circuit board with acid. If you are inclined to do this, best do it before it fails. But most of us don't do that because we don't want to fix what's not broken.
Got an OEM siren from Ricambi and installed. All is as it should be..chirps, lights and siren noise. I contemplated using the GM fix mentioned by a few folk, but I personally believe things should work as they were intended. Apparently the GM product flashed the lights, chriped the chirps but gave no siren noise. Just thought about someone tampering with the car if you're not in visual contact with it. Not much good if you can't hear it shouting for help. If the GM bit worked identically I'd have used it. The date stamp on the old unit (made in Australia) was 2003, so it lasted 13-14 years..not bad. New one (made in Hungary) is stamped 2016 so I should be good for a while. I know some of you folk like playing with these things, so if anyone wants my old unit...free to good home...just drop me a pm. Again, thanks for the input that directed me to the siren.
I opened the old unit up . Board is perfect. 1 battery gave the required voltage...other was dead. If nobody wants this old unit to play with it's going to trash. If you want it...pm me.
so, I’ve got a 2003 360 Modena and as of today I have a constant red dash LED as the car is running. So obviously my siren battery is going out. My questions are: how long will it remain in this status? Is total siren failure imminent? I’ve had the car 6 weeks and the siren never chirped so I knew the siren battery was heading south- and, Once the battery is fully dead, can the car still be started as normal? Just with no alarm? I’m contemplating my next move- I can get a new one from a guy on F-Chat-or try to save my old one with a new remote battery install. No idea if the circuit board is fried, need to get it out and apart . thank you Greg
Basically you're asking "how long is a piece of string". The siren only becomes an issue if a leaking battery destroys the circuit board leading to, in some instances, a short circuit which blows the Immo system fuse. The faster you get it out, the better your chances will be of salvaging the siren circuit board, but that's only important if you don't have the budget to buy a siren from "a guy on FChat" (Gobble) .... or your skillset and toolbox won't allow a DIY repair. I had the funds to buy a new siren, but attempted a DIY anyway. I opened up mine a few years ago with a knife & a lot of effort, with only one small scratch on the case, but I thought I would make a mess with the glue, so I bought one anyway. Now I have a spare siren (in halves). If I ever use it, I'd need to buy a second set of batteries as they are getting old.
Thank you Qavion--yes,. Gobble is the guy--we recently had a conversation where we discussed his help in retrieving my PIN code, making an all-in-one key, and providing a new alarm siren. Contemplating all of it--but I'm fairly handy with tools-so I may attempt removal/dissection/battery renewal before I sink $$$ into a new siren. With the old siren out of the car, can it be started and ran as normal? I would guess that's a big, fat NO! TY Greg
You can run some Ferraris with the siren completely disconnected. Give it a try. The LED will probably show the same behaviour though.
