Your car thinks it is being stolen - jump starting a car looks a lot like hot-wiring a car to the computer. You need to do something that tells your car "it's OK, I own you". You can do this right after hooking up the cables, but before starting the engine, to minimize the annoyance to your neighbors. If you have a remote door key, lock and unlock the doors ...

From the owners manual. Alarm Stage The alarm will be activated if any of the following occurs while the car is parked and the system is armed. A front or rear door is opened without using the transmitter or the ignition key. The trunk lid or tail gate is opened without using the transmitter or the ignition key. The hood is opened. ...

For a really quick solution, try getting hold of a spare seatbelt from a scrap vehicle (I doubt the shape changes often, so I expect any reasonably recent Toyota would do, just get one that is the same as the belts in your car). Remove the tongue (The t shaped bit) from the belt, and keep it to hand - then, when you're driving on the trails and want to ...

The Volvo V70 factory alarm siren has a battery that would probably be bad by now. It's sealed in. When the voltage drops it will cause the alarm to go off for seemingly no reason. Check that first, its a common issue in several Volvos. Prevention would be by replacing the battery prematurely every few years although it's not particularly easy or simple and ...

Obviously the easy fix is replace the battery in your FOB then just hit unlock once you hook up the battery. But... If you are too lazy to replace your FOB battery. Try just putting the key in the ignition in the "ON" position then hooking up the battery. If that doesn't work then try cycling the key between off and on (not start) 5 times. If that doesn't ...

Well, the thing is, you already have this two different ways in the car. If the transmission is not in Park or Neutral, the ignition should not release the key. If you open the door and the key is still in the ignition, there's a beep or a buzzer that will let you know. The hand brake, when applied, turns on a red light on your instrument panel. How did ...

I have a workaround and its been in place about 6 weeks over 1 year now, so I feel confident to post it. I left the vehicle with my prefered independent mechanic for two days. Regretfully the alarm didn't go off once in his care :-/ Similarly I took it to my local dealer and had their "alarm specialist" look at it. Again nothing found. But the next day, ...

According to the owner's manual I found online, once all doors and trunk are closed, then locked, the alarm automatically activates after 30 seconds. There may not be an external indication of this, other than the indicator on your central console which will go from "solid on" to "flashing," once the system is set.

Check to ensure you have enough fluid in the brake master cylinder. A lot of vehicles have the sensor which detects the level of the fluid in on the same circuit as the parking brake. If you find this low, you may want to check the condition of your brake pads. If the brake pads are thin, there is more fluid residing in your calipers which would in turn give ...

By far the most common electrical problem, especially in cases like this where "mysterious" things happen, is a bad ground. They're usually very hard to find but very easy to fix once found. Basically you want to use a multimeter to measure the connection between the negative battery terminal and different places on your car that should be grounded, like the ...

If the alarm is a "factory" alarm, cycle the key in the ignition from off to on (where the dash indicators light up), 5 times. This is the reset procedure for the "factory" alarm. Otherwise look in the owners manual where there is a red button under the steering wheel, possibly behind a panel. These process is performed when doing maintenance. Either way, ...

from wikipedia: Certain car manufacturers use the 2.4 GHz frequency for their car alarm internal movement sensors. These devices transmit on 2.45 GHz (between channels 8 and 9) at a strength of 500 mW. Because of channel overlap, this will cause problems for channels 6 and 11, which are commonly used default channels for Wi-Fi connections. Because ...

There can be multiple explanations for this: 1. Disabled the speaker through OBD port (some manufactures give you an option to disable this in the software using a laptop connected to your OBD port). This can only be done with special software and hardware. 2. Unplugged/removed the physical speaker under the dashboard.(This happened to my car, they just ...

Maybe someones google skills are better than mine. I wasn't able to find custom firmware to flash the Smart Junction Box and disable the perimeter alarm. You would still need a J2534 device to accomplish this. If you have access to the Ford IDS or an aftermarket EOBD2 scantool you can go into the body data to find the malfunctioning switch. These two ...

Same thing just happened to my 93 landcruiser...changed battery and alarm kept going off, it shuts off after a few cycles but the immobilizer would not allow the car to start. Tried everything, and while all cars are different here’s what worked for me: disconnect the negative terminal, put the key to the ‘on’ position, leave the drivers door open, reconnect ...

I found these instructions on this site. According to the instructions, the battery is a simple CR2032 battery, found anywhere you can find batteries (like Wal-Mart, or whatever). If there is a second transmitter, use it. If not, you can try opening the door with the key, then using the key in the ignition. This works in some vehicles, but once the alarm is ...

With very old aftermarket electronics the only real thing that can be done is removing the system. With aftermarket electronics there is little to no support, no replacement parts and no predictable failure mode. Before you drive your self insane or get stranded somewhere when the system fails altogether, remove the immobilizer system.

I believe the best place to make this change would be at the fuse box using a separate fuse. You will need a wiring diagram for your vehicle to identify the wires going from the fuse box exclusively to the bulbs. "I need to supply to each light individually - or just one and the current will spread to the rest?" Each bulb needs to receive current from its ...

If it's a 55 plate I assume it's either a very late Mk IV or most likely a Mk V. The Mk VI didn't start until 08. I suspect that it's most likely to be a wiring issue with the module in the drivers door. This could be caused by a trapped wire within the wiring that goes through the A-post or (more likely) moisture / water ingress which is usually caused ...

We were dealing with a similar problem with a 2003 Odyssey. We watched the YouTube video and disconnected the hood switch connector, and the problem was improved for several months. Out of nowhere the alarm started going off when opening the door, turning on/off the ignition. The red flashing "alarm" light was clearly visible on the dash. I took the ...

In my car, the reason for the alarm going off randomly was water leaking from the "body seam" on the roof, through the left front pillar, and zapping the computer.

Basically, you want a device to activate when the 'system' is 'armed' and the door is opened. The easiest way to do this would be to tap into one of the outputs of an existing system, or install an aftermarket alarm system. If you want a completely different system, you will need door pin sensors to determine when the door has opened. You MIGHT be able to ...

The safe way of turning seatbelt chime/alarm off During these steps, do not touch the brake at all shut the door. turn the key on and get your instrument panel on ODO and turn key off. turn the key back on, press reset knob immediately. hold reset knob for 12_15 seconds and fasten the seat belt. xxxx miles should turn to b_on. release and press one time, ...

I was mistaken when I said the module was in great shape. Although the battery had a good charge and the circuit board was intact, I later noticed that the connection between the two had a significant amount of corrosion. On cutting the battery wires, I found the metal strands of the ground (which was suffering from the corrosion) appeared black as if they ...

So I found a manual inside the car that has some information on how to disable it. Apparently the security system is from a company or brand called VPS. The solution was to quickly turn the key in the ignition from ACC to Ignition 10 times in a row. The car was then started. Hopefully this will help someone else.

If you said what make, model and year the car was it might help, if that model was available with motion, ultrasonic or tilt sensors it will be possible to retrofit them. Retrofitting a factory option can be as straight forward as installing the necessary parts and plugging in some connectors. Sometimes you will need to get certain control modules ...

You can get extremely cheap and low-power motion sensors (PIR type). They consume current in the microamp-milliamp range (5V) when active, so it won't run down your battery. When triggered by motion, they shoot a 3V3 signal out, which can be used to trip an alarm. They're small; 35x35mm. Just pull a wire from 12V to a voltage regulator (7805 is very cheap ...

recently... i have done this before. What i'm doing is... i connect directly to left/right respectively. one wire connect to left signal and another one to to right signal. For simple car, i think should be no problem. My car so far so good.

Here is the wiring diagram and all sensors (switches) that could be faulty. You could disconnect the connector from the Drivers Mutiplex Control Unit and test the sensors wires to ground, there should be no continuity to ground with all doors, hood closed. Unfortunately I don't have a location for it.

If your car has a vibration sensor, you can typically set the sensitivity. You can test this by bumping into your car or trying to rock it a bit.
