Alarm system problems?

Is it factory or aftermarket alarm? If an aftermarket alarm has been installed cut it out and reconnect the wires the way the factory had it, if its a factory alarm it could have a door switch that is not adjusted. With the alarm set try to pull on each door it see if the alarm goes off. This would be the door that's needs a new latch.

After reading the wiring diagrams for the anti-theft, power door lock, power windows, and keyless entry system, it is inadvisable that you unplug the anti-theft ECU. I believe all operations I have mentioned go through the ECU to work.

The diagnostic in the TSB suggests that you check the anti-theft horn (#4l) and its fuse (#1) in the picture. Here is the caveat. You may either pull the fuse or unplug the horn wiring harness. That will be safer than unplugging the ECU.

Hey DNSPARKS,

It is usually an aftermarket alarm that go off on there own, does it have a security light that flashes in the instrument cluster?

Best, Ken

How old is the battery?
Battery has to have at least 12.4 volts and must be more than 11 volts when ignition is turned to START.

I believe you have a bad battery or loose connections.

Try a new remote an dsetting it up like it's supposed to be. Any car alarm company should be able to help you out.

It sounds llike you might just have a weak or dead battery. Are the headlights bright before you try to start the engine? I assume this is an aftermarket alarm system since factory systems don't use reset switches.

The battery cables could also be loose or dirty. If jump-starting doesn't help, grab a cheap digital voltmeter and measure battery voltage. I can walk you through that if you need help.

Dandy.

When you said, "I'm not able to get any power to the car for a while I have to take the battery off for a while then hook it up to get power", do you mean no power to the starter, or does that include headlights, dome lights, and stuff like that?

Ok. Do you have a digital voltmeter or test light that you can take some measurements with?

Start on the two battery posts. You should see near 12.6 volts if the battery is fully charged. Turn the headlight switch on. We want to make these measurements when everything is dead, but to be safe, leave the headlight switch turned on. By the way, if you bump or wiggle something and the lights come on, look very closely where you're working. Tiny sparks too will be a clue.

If the battery voltage is low, say around 10 - 11 volts, the battery has a dead cell and must be replaced or it is discharged and must be recharged before continuing. If the voltage is around 12.6 volts, move the probes, one at a time, from the battery post to the cable clamp on each post. Both times when you move a probe, you must see the same voltage. If the reading drops when you measure on one of the clamps, that clamp is loose or has corrosion in the connection.

Start with those measurements. If you always read 12 volts, we will need to keep moving the meter probes down the cables to more test points until we find where the voltage drops.

Hello,

DIsconnect the battery for 1 hour then connect it with the key on this should disarm the security system.

Please run down this guide and report back.

Ifit is a factory alarm, locking and unlocking either th edrivers door or thetrunk will reset it. If aftermarket, you may need to have it removed/by passed, it is a fairly simple job.
