Question about 1996 Jeep Grand Cherokee

1 Answer

Factory security system draining battery

We had trouble with the security system coming on and locking everything up and an apparent short was cutting the motor off and draining the battery. We replaced the battery and checked fuses, thought we unhooked the system, but we had the vehicle valet parked the other day and its dead as a door nail. Jumping only lasts so long before whatever is triggering the system shuts the vehicle down again

Got a manual dont bother no mention of security system components

There have been problems with electronic alarms draining batteries and locking out etc caused by RF interference.

This can be from Phone transmitters, WiFi hubs or other sources of RF energy.
Basically - the alarm is staying awake reading every piece of interference - and after a number of attempts locks out.

You could try contacting the manufacturer - to put the system onto a different frequency, or reduce the sensitivity by shielding the aerial of it - or find the cause of the RF problem.

Contact here again if this doesn't solve it.

Thanks.

My 1999 Bonneville will be sitting in a parking lot at work or at home and the alarm will just start going off. No one is around or close by with the keyless remote.\r\nWhat is causing this and can i...


A lot depends on exactly what is happening here. Are we talking about an aftermarket alarm system? If so, I personally would recommend removing the entire system - they are usually more trouble than they are worth! (Just my personal opinion based on 36 years of auto repair experience)

NOTE: The information below applies ONLY to problems with the FACTORY security system.

There is a possibility that the horns going off are not being caused by the alarm system at all. Some GM airbag modules/steering wheel switches have been known to short out intermittently and cause the horns to sound for no apparent reason. If the horn is staying on solid (BEEEEEEEEEEEEEEEEEPPPPP) then it is most likely NOT the alarm system. If it is beeping on and off at regular intervals (BEEP.....BEEP......BEEP...) and the headlamps are flashing, then the security system is probably at fault.

Low battery voltage or a shorted cell in a battery can "trick" your alarm system into "thinking" that someone is trying to steal your car. A THOROUGH battery and charging system check should be performed to find out if this could be the cause.

Also, your factory alarm is a PassKeyII system. This means that if there is a malfunction in the system, there is most likely one or more fault codes stored in the Body Control Module (BCM) that can lead you to the cause of the problem so you can get it fixed.

Please note that MOST generic code readers CANNOT access these type of codes.

Another way to work around this is to "disarm" the system. To do this, unlock the door using the key. Press the "unlock" button on the door. Then press the "unlock" button on the key fob (keyless remote). The system will disarm. When you leave your car, use the KEY, not the remote to lock the car. (If you use the remote, the system will be armed again.)

Where is the negative ground cable on the firewall? I have a brand new battery and alternator and the car continues to drain the battery.


at the battery....visually trace the neg black wire to where it is secured...but problem may not be in the cable, if everything is tight.I'd rather suspect grounding/short in the headlite system...most headlites are not fused...also a faulty starting system can easily drain the battery......whatever is shorting is not fused

I installed a new battery because my other was drained.when i hooked up the new one, my locks keep locking over and over again, so im guessing thats why my old battery was shot.what do u think caused this?


does the vehicle have an alarm, or security system? cause sometimes when a battery dies, you need to reset that system inorder to have that problem get fixed, if not then there is a short somewhere in the electrical system... hope this helps you out...

No Go!!!!


Explain "jared" - if hit hard enough - check SRS system - check factory security system [related to "beeping"?] - check for shorted wire near starter - just a few suggestions.
