This light usually refers to the vehicle's Immobiliser System. Has this light just started to come on recently? Some Nissan models normally have this light flash when you walk away from the vehicle to show that the Immobiliser is active and working correctly while you are away from the vehicle.
If this light stays on when you try to start the vehicle it usually means the security system (the immobiliser) isn't recognising the key you are using. Are you having problems starting the vehicle?
If this is something it has just started doing try this simple fix first. Change the battery in the key fob for a good quality new one. An old battery can sometimes give a weak signal which the security system cannot read correctly and assumes it's an attempt to steal the vehicle.
Is the vehicle's battery in good condition and fully charged? Have you disconnected the battery recently? Some immobiliser systems need to be reset if the battery is removed for long periods.
The light will only quit flashing if there is no problem, So you must have a problem. Do this get to the diagnostic mode only this time count the flashes these are codes, it will look like this example a flash followed by Two fast flashes is code 12, Three long flashes followed by Three short or fast flashes is code 33. When you get the code use the testimonial to tell me what they are. It will show up in my email. I hope this helps. Take care.
If it is not a new key fob, it sounds to me like the immobilizer is activated. So, all the lights on the dash are working now? Is there a flashing key on the dash lights? One of the resets that works is put the key fob in, and turn ignition on without starting it, and leave it 15 minutes. And try again.
Immobilisers may intercept one of three circuits; typically the low-voltage ignition circuit and the fuel pump circuit. Some may also intercept the low-current starter motor circuit from the key switch to the relay. The Immobilisers can be set to intercept these circuits IF you use a key that has been copied or someone tried to start the car with the key for another car. Once activated, most of the time they are on a timer, meaning they will reset in 10 to 20 minutes. You can try and reset yours by disconnecting the battery, remove both cables and touch the two cables together for ten minutes. Now if you have a radio that needs codes to reset it be sure you have the codes before disconnecting the battery. Some Immobilisers use a magnetic switch to turn off the car. buy disconnecting the battery and touching the cables together you will kill the magnetic field and reset it. Hope this helps fixya up.
the "puddle lights" should go out about the same time as the interior lights,after removing the key from the ignition,if not try an alarm/immobiliser system reset as per the book.
6-turn key to on (not start) then off, twice this is rewrite mode,have all remotes to reprogram it will clear any lost remotes.
7-remove key from ignition,the door locks should cycle twice.if not start over.it may take a few tries.
8-press lock/unlock together and hold for a second
9-release,and press lock on remote,the door locks will cycle
confirming program.continue to do other remotes you have,steps 8 and
9.if only one in possession,you are done. To end mode open door or insert key into ignition.
You'll need to follow the steps with no more than a 1-2 second delay between each step.. hope it works
Hi
Had a similar problem with my x type 2.5 petrol, only had the car 1 day went to start it nothing happend all the lights came up on the dash but the engine wouldn't start and the immobiliser light stayed on. Spoke to Jaguar they had no idea and I couldn't get it to them. After disconnecting the battery trying to reset the immobiliser phoned and auto locksmith they came out and discovered the end of the key with the blade had lost it's coding and the immobiliser was not disarming, they reprogrammed the key and the car started no problem. As far as i know there is no way past the immobiliser. Hope this helps.
