Why the theft signal keeps on

The theft signal always on

My car has 100 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there. More often than not, this problem is caused by a stored error code inside the ECU that keeps the security light illuminated. If you recently replaced a battery or other primary electrical component, this may have triggered the error code in the first place. It is probably a good idea to have a professional mechanic come to your location and first complete a check engine light inspection, so they can download any stored error codes, clear them and see if this resolves your issue.

With a life expectancy ranging from 150,000 to 400,000 miles, the 2006 GMC Envoy could serve as your ride for 20 years or more. Where your Envoy falls on that mileage spectrum depends almost solely on regular maintenance.
Envoy and Envoy XL models are equipped with a 4.2-liter inline-six-cylinder. It`s been upgraded for 2006 and now boasts 291 horsepower, up from 275 hp in previous years. Envoy Denalis feature a 300-hp, 5.3-liter V-8 that uses Displacement on Demand technology. All models use a four-speed-automatic transmission.
fits the following vehicles: 2006 4.2L GMC Envoy/Envoy XL. This auction is for one service number 12597521 ECM (Engine control module) that is programmed for your vehicle.
The model year that received the highest overall customer rating and reliability ratings is the 2006 Envoy, scoring 85/100 in both categories. The model year with the lowest reliability rating is the 2007 Envoy, with a score of 83/100.
has a top speed of 150 miles per hour**.
The 4.2L straight-6 Vortec engine is extremely reliable. Worn valve seats are the only problem on our list that can lead to an expensive repair bill and the issue really isn`t common enough to give any worry. The fan clutch, water pump, sensors, end links, etc. are all very minor and inexpensive problems to fix.
Engine Oil

Capacity: 7 quarts (with filter).

A faulty ECM can send poor data to your vehicle`s transmission control module (TCM). As a result, the vehicle cannot properly shift gears or apply power, causing the shift to feel awkward, delayed, or even jarring. When this occurs, the engine may sporadically become more active or stall out.
The Envoy is a five-passenger SUV that also came in an extended seven-passenger version, as well as in the form of a versatile cargo wagon called the Envoy XUV.
About Envoy

In 1998, the GMC Envoy was introduced as a luxury version of the mid-sized sport utility Jimmy. Standard equipped with four-wheel drive the 1998 GMC Envoy was powered by a 4.3-liter Vortec V-6 engine connected to a four-speed automatic transmission.

Of the GMC SUV lineup, the 2022 GMC Terrain offers the best mpg ratings with up to 25 city and 30 Max Highway MPG.
3.0L Duramax® Turbo Diesel l6 Engine

Plus, the Duramax engine offers the best-in-class horsepower and an incredible highway driving range of up to 660 miles. The 3.0L Duramax turbo diesel I6 engine is available in 2WD or 4WD and is paired to a ten-speed automatic transmission.

Remember how the starting, stopping, and idling, with the idling add up with the engine mileage. With those factors considered, an engine overhaul may be needed at around 750,000 miles. Once the engine overhaul is completed, you can expect to get another 10,000 engine miles of driving and/or idling time.
About Timing Belt Replacement

Newer models use timing belts made of polyurethane and Kevlar for long life and durability. They can go as long as 100,000 miles although it`s always a good idea to change it before then. Belt failure can cause extensive damage to the valves, pistons and other internal parts of the engine.

Turn signal lights keep failing, how can I fix this?
ANSWER : Your problem is electrical, and all of the components involving the the turn signals will need to be inspected. Unfortunately it takes some trial and error in testing to find the component that is failing. Considering the hazard button tends to have an effect, you want to concentrate on the components these two parts shared.

Start by checking the multifunction switch. These switches can fail or have a bad connection giving you the intermittent symptom you’re experiencing. Another component they share is the flasher unit which sends the signal back and forth between the left and right side of the car. These typically won’t be the cause of symptoms like you have unless the connection to the flasher is damaged. The wiring connections running through the steering column can become damaged, but it is likely a switch at fault.

Further testing of your turn signal light is needed and it may be done best by a technician who is familiar with tracing electrical problems, such as one from YourMechanic.

Turn signal problem
ANSWER : When you turn on the turn signal on the right side do you get a light in front and rear come on but not blink? Do not have headlights on at this time. Replace the right front turn signal bulb if it does not light. Then replace the left rear bulb with correct bulb for vehicle since using wrong bulb will cause fast blinking and a bad bulb will can cause no blinking at all.

Electrical Short/Power dimming when brakes pressed. Turn signal fuse blowing. 1980 Dodge B200
ANSWER : Hello – you have electrical problems for sure, possibly more than one. A short in the steering column wiring seems likely. This problem can be diagnosed by connecting an ammeter to the positive (red) battery cable, observe the current drain (likely less than 1 amp), then, one at a time, remove each fuse, check to see if the current drain has dropped to near 0, then reinsert the fuse. start with the brake/turn signal lighting circuit. This process should identify the faulty circuit in most cases. The specific components on that circuit can then be checked for current drain problems. A professional mechanic, like YourMechanic, can come to your location, and perform this procedure for you, and replace/repair the failing component.

How can i disable the anti theft system, the light keeps blinking?
ANSWER : Hi there. Aftermarket alarm systems can create problems, typically from poor installations. The vehicle’s wiring harness is usually tapped into and removal of the alarm system is more than just pulling a fuse. Most aftermarket alarm systems are installed under the dash, driver’s side. The aftermarket alarm removal can be complicated and should be professionally done. The aftermarket alarm may not be causing the no start condition. Proper diagnoses should be performed to avoid unnecessary repairs. I recommend having your vehicle’s no start be diagnosed and repaired by a certified technician, such as one from YourMechanic.

Turn signals keep blowing fuse under hood
ANSWER : If the fuse blows as soon as you put it in then you have a direct short and may have a bad flasher relay in the interior relay fuse box. Remove the relay and see if the fuse still blows. If it does not blow then you may have a short in the wiring of the light circuit or a problem with the relay. If you just got the car then look in the left kick panel and under left side of dash to see if you see bare wires or where an aftermarket alarm has been removed. Unfortunately you may have some bad re-connections and tape up jobs.

Chrysler car, replaced turn signal switch and flasher relay and turn signals still do not come on either right or left, no turn si
ANSWER : Hello, thank you for writing in. If the electrical components are all working individually, then the issue is likely relating to the wiring between them. The best way to trace the issue is with a voltmeter. In doing so you start with the power supply starting at the fuse box and work your way down the circuit. When you find where the voltage cuts off, you will have found the wire or component that has failed. You will want a wiring circuit to help you through this process. Often when after market components have been installed around the wiring it can become damaged. Double check any of these areas. The switch and steering column will both need to be tested as well. For more help with this type of electrical testing, contact our service department.
