It is possible that this warning is indicating to you that your key fob battery is dead or dying. I would recommend looking in your owners manual as it will likely give you information as to what this warning message means. There is usually a section in the owner’s manual that shows a picture of all the warning lights and what they mean. If you are unable to find information in your owner’s manual about this issue, I would recommend going to your local Infiniti dealership to inquire.

The security indicator is white and contains a key inside a car. This light will blink whenever the ignition switch is in the Lock, Off, or ACC position. This warning light simply lets you know that the security system is on. You can find more information about your vehicle`s security system within your owner`s manual.
The red key warning light means there is a security error code. This light illuminates when the vehicle control modules see the ignition turned with a key that is not programmed to the vehicle or when there is an error within the security protocol of the vehicle`s security system.
The key light is telling you that the key is either not detected, or the key is not recognized. This could be the failure of the key, key battery, or an issue in the anti-theft/wireless control system.
There are 3 different categories of warning lights; red, amber and green: Red warning lights mean you should stop the car as soon as it`s safe. Yellow warning lights mean that action is required. Green warning lights are for information only.
An antenna or wiring fault in the keyless entry system, software issues, a damaged circuit board, or a faulty start button are all possible culprits. Consider having the vehicle inspected for any repair needs.
The green key icon is for the immobilizer system on your vehicle. Your ignition key has a chip in it and the computer won`t allow the engine to start if it doesn`t recognize the chip in the key. When that happens, or if there is a malfunction in the system the key indicator light will flash consistently.
Vehicle-Specific Key Resetting

The process of reflashing your transponder key will reprogram the car`s immobilizer, setting it back to the original factory settings. After reflashing and reinstallation, the car will be in “learning mode” and will accept the use of new keys.

If I change the battery in either the car or key fob do I have to reprogram the key fobs? No, The key fobs use non-volatile memory, meaning that they will never lose their programming if power to either the key fob itself or the module is lost.
When you open the bottom of the fob allows you to access the mechanical key. You can unlock your car with the mechanical key, which will allow you to open your vehicle. Your keyfob is not essential to start your car, as automakers have designed the ignition button to work even if the keyfob fails.

ANSWER : It is possible that this warning is indicating to you that your key fob battery is dead or dying. I would recommend looking in your owners manual as it will likely give you information as to what this warning message means.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

Car shut down and will not start. Warning lights are on – 2006 Toyota Highlander
ANSWER : Hello. From what you describe, it would appear that your vehicle is having some sort of electrical issues. The "Generator Inverter Performance" warning comes on when the computer detects an issue with the vehicle’s electrical generator inverter. The generator inverter is the component that converts the high current electricity from the vehicle’s hybrid battery into a lower power form of electricity that is useable by the vehicle’s various systems.

The inverter is located in the engine bay, as the silver box on top of the engine. Unfortunately, the inverter is a critical component to the functionality of the hybrid system, and therefore to the operation of the vehicle, and, as a result, needs to be repaired or replaced before the vehicle will run again.

The VSC system warning light comes on when the computer detects an issue with the vehicle’s stability control system. This is usually due to a fault with the wheel speed sensors or the ABS module, though electrical issues can sometimes effect this system as well and cause it to behave erratically. I would start by taking care of the generator inverter issue and going from there.

I recommend having a certified mechanic, such as one from YourMechanic, perform an inspection to determine why the warning lights are on and suggest any needed repairs.

I am not getting any power when I turn the key to the on position. there is no dash lights only check engine lite comes on.
ANSWER : The problem of having erratic electrical issues with this year Bronco they have problems with the ignition switch losing contact. You should check and replace the ignition switch. When the switch is removed you should check linkage rod and electrical connector for problems and repair as needed along with replace the ignition switch.

Low coolant light comes on when AC, defrost or heater is on, but only if the car is in gear and stopped, what’s wrong with my car?
ANSWER : First, you want to make sure your cooling system is full. Check the radiator not the coolant jug. And check it when it is cold. If it needs coolant, add some. Of course, I don’t feel this problem is an actual low coolant condition. I would expect to find an electrical failure in the instrument cluster or from a component or wiring harness that is connected to the instrument cluster.

As a technician, I have access to reports from technicians across the country. I could not find any reports of this problem, so diagnosing this will require an experienced tech as this is not a common problem. In addition, this happens at intermittent times making it difficult to recreate. The most challenging part of this diagnosis will be recreating the symptom. I suspect it has something to do with the brake switch circuitry because it only seems to happen when you have your foot on the brake. I would begin my diagnosis there with a wiring diagram and test light in hand. The brake switch, instrument cluster, and environmental controls all interact with each other. Something is crossed either because of a failed module or damaged wiring in a harness.

Aside from making sure the coolant is full, this will not likely leave you on the side of the road. If you take it in to be diagnosed, be prepared for them to spend more time than usual to figure it out. Since it isn’t a key problem, you may need to live with it until it completely fails making it much easier to diagnose. Either way, I do recommend having a certified mechanic diagnose the warning light to make sure there isn’t anything serious going on.

Good luck.

Every time I put my key into the ignition lights flicker, radio comes on, and check engine light comes on.
ANSWER : Hi there. There is an issue with the ignition switch when you are turning the key. The tumbler may have worn contacts within the switch causing the lights to flicker and the radio to come on when it is turned off. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose an electrical short or loose ground in the ignition switch circuit.

voltage warning light still coming on 30-45 seconds after car starts.
ANSWER : Nothing should be replaced until you have in hand a definitive diagnostic pinpointing the faulty segment of the car’s electrical system. There may be too much voltage drop in the charging circuit, as well as elsewhere, but start with the charging circuit. The faulty segment could be anywhere, so using the factory wiring diagram you just have to methodically and systematically test the entire charging circuit until the fault is found. It’s laborious but compared to replacing parts that might be perfectly good, properly diagnosing the fault will save you money and time in the end. As far as the engine warning light, at the moment I would fix the issue with the charging system first because that may resolve the check engine light. If it doesn’t, just request a check engine light diagnostic. If you want the charging circuit diagnostic steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a charging circuit diagnostic and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.
