Magnum won't start!!!!

[injunwiz]

I posted in the Magnum section of the forum, hope I'd get a few ideas of how to fix it without waiting for Monday and a tow to the Dealer. Here is my problem, I disconected the battery and later when I reconnected it reset the auto window feature first. When I turned on the key to reset for the ESB the car started for a few secs then dies. I just installed a catback so thought maybe that had something to do with it. I tried restarting and after the 3rd try NOTHING. THEN I went on the forum and read about the red light on my dash! I did look around and found this:


There are two seperate systems at work here, VTSS (Vehicle Theft Security System/factory alarm) and SKIS (Sentry Key Immobilizer System). the batteries are only used for the transmission of a radio wave signal to disable VTSS (Vehicle Theft Security System/factory alarm).

there is a transponder inside the key which gets excited when in close proximity to the SKREEM/WCM (Sentry Key Remote Entry Electronic Module/Wireless Control Module) antenna (halo ring around ignition key hole). once excited, the key transponder transmits a secret key code to the SKREEM/WCM. this works the same way as MOBIL Speedpass, no batteries required. the SKREEM/WCM will then transmit this secret key code information to the PCM (Powertrain Control Module) to allow engine operation.

if, for any reason (read broken battery clip), the key fob fails to transmit a VTSS signal to the SKREEM, the result will be RKE (Remote Keyless Entry) inoperation and, when opening the driver's door using the key lock cylinder, activation of the VTSS alarm. however, the VTSS alarm can still be disarmed by turning the ignition key on. by doing this (key on), the SKREEM/WCM signal (Sentry Key portion) will disable the VTSS alarm. you may also get a "low battery" warning in EVIC (Electronic Vehicle Information Center).

if, however, the SKIS transponder in the key fails to transmit a valid secret key code to the SKREEM/WCM, the result will be a start/stall condition accompanied by a flashing red dot in the instrument cluster. after repeated attempts, the engine starter will be disabled until the PCM receives a valid key signal from the SKREEM/WCM.

QUESTION: how do I get a valid key signal? I tried pulling the IOD fuse, disconnecting the battery (didn't work), and now have it sitting with the key in the "on" position and a battery charger on it. I'm gonna wait 1 1/2 hrs. ane see what happens. If that doesn't do it then what? I have no car 'till a tow and dealer visit on Monday! Thanks for any help...

I had the same problem on the fuse box next to ur battery pull off the iod fuse while the battery is till pluged in and key in ignition on off position leave fuse off for 20min so the computer will reprogram then pop it back in and turn car on it should work

[injunwiz]

I've had the car on the battery charger for 45 mins. with the key left on so far so I think I'll wait 'till the 1 1/2 hr mark and see what that does. I did pull the IOD fuse but only for about 30 seconds and I don't remember if I left the key in the ignition. If the in-process idea doesn't work I'll try your method. Thanks!

If you have a spare key use that or what I ended up doing while on the phone with the dealer was with the key in the ignition I locked and unlocked the doors as soon as the locks moved the light went off and my car started. If your battery in your fob is dead you'll need to change it first becareful though I read in other threads about the tab that sometimes breaks when changing the battery. Good luck.

I have a 2005 dodge magnum with a 2.7 v-6. I turned it off, and it hasn't cranked yet. 1) I checked the battery voltage with a load tester, and was good! 2)I checked the starter by using a push button remote starter( it rotates) 3) I changed the battery in the key fob, and pulled the iod, and let set for two hours. 4) I checked all the fuses,relays,wiring, and everything else, and it still dont work! When you turn the key to the start position you hear clicking at the rear relays in the back where the rear distribution box is. the red light beside the fuel gage stays on, and was told that unless that goes off it won't crank, meaning lights and all acc's work but won't rotate the engine to run. I DESPERATLY NEED HELP!, I LOST MY JOB BECAUSE OF CUT BACKS, AND HAVE THREE KIDS THAT I'M RAISING ON MY OWN, AND REALLY NEED THE CAR FOR TRANSPORTATION. IF ANYONE COULD HELP, i WOULD DEEPLY APPRECIATE IT.

As I understand after three atttempts the system locks you out and requires the dealer -- no way around it. I just ruined my last key tried to start twice -- not going for three hopefully won't need to tow it in.

I haven a 06 RT that was a theft recovery. Everything works, fuel pump runs, stuff like that. I had new keys cut and scanned at the dealer. Nothing. They said there was no codes in the car. So why won't it crank? I've tried the unhook the battery trick and still nothing. Any help, thanks.

first off. the red light is the imobalizer systems or skreem. wcm module.

yes if the light is on this is some type of fault. the light should come on and then go off. . alot of people have had this issues by pulling fuse 11 to reset learned adaptives but a negative is it sets loss of communication codes and in other cases your issues start. with out taking it to a dealer the best thing to do is leave the battery discconnected for a while preferable over night.

the battery within the key does not affect the system. the battery in the key is specifically for the lock unlock etc. the senry key works on a radio frequency to a pelet in the key then a return frequency.

does any one remember those led lights they used to put on the antenna of phone like the nokia 5100 etc well thats the same deal it gets power from the radio frequency transmission. hence why the grey sentry keys work and they do not have any batteries.

any ways yes if the red dot light is solid and does not shut off your car is not starting do to an invalid key communication error or internal skreem system failure. if all you did was remove the battery or pull fuse 11 then most of the time leaving the battery disconnected for a long period of time IE over night etc will allow all the power in each module to drain off this doing a full system reset.

oh btw standard problem especially in the first year cars of the new style keys . ie 08 charger 40 out of 50 times the key module or WIN module is bad.

try bypassing starter relay to eliminate starter circuit problems.

Hey Funky - I am having a VERY similar issue - Can you tell me exactly what to jump to bypass the relay?
I'd be grateful??

Take the positive off of the BATTERY and touch the cable to the ground. This will discharge ALL the capacitors. I had to do this for a friend that had a Journey. Works like a charm and instantly.

remove relay and temporarily jump cavity 30 & 87.

[RickShadetree]

Thanks!
Will give it a shot when I can get back to it.

Thanks JC!
Will send that info to my son and ask him to try it!
I certainly appreciate the help!

[RickShadetree]

Dang!
Gave that a shot and no go.. Just to recap..
Click when trying to start.
Remote unlock inoperative.
Won't jump start.
Pulled an 0571 from the Key dance.
Surface Voltage 12.6 (Jumped voltage 13.5) on battery
No "real" load test on battery (yet)
No Security System Arm \ Disarm flash when using remote.
I am ready to light this thing on fire! LOL (kidding)

Started after Mama got an idiot light on the Fuel guage, turned the car off and put 10 in, then this issue beagn

Thans for all the help guys, if you've got any other tips\tricks to throw out there, I'd be happily amazed. Maybe I'm just gonna have to keep it in the driveway until I can afford take it to the Dealer!?
Anyone wanna buy a Gibson SG Guitar???
