my5thgen 00-03


This seems to be common on the 2002-2003 Nissan Maxima’s. Below is a procedure you can follow before going to the dealer.

Possible causes:

  • Faulty or not programmed ignition key
  • Faulty IMMU
  • Faulty Engine Control Module (ECM)

This code is usually triggered when a not registered or damaged key is used to start the engine. When the starting operation is carried out five or more times consecutively with the same unregistered key, the system will lock. If the problem occurs try disconnecting the car battery for about 30 minutes and then try starting the engine with a known registered key. If the problem persists you have to have the dealer erase the code and reprogram the keys again. If problem persists after disconnecting the car battery, try the following:


1. Turn ignition switch OFF.
2. Turn ignition switch ON with registered key. (Do not start engine.) Wait 5 seconds.
3. Return the key to OFF position.
4. Repeat steps 2 and 3 twice (total of three cycles).
5. Start the engine.

When is the code detected?
When the starting operation is carried out five or more times consecutively with an unregistered ignition key or faulty key.

Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Engine would not start

P1610 Nissan Description
An immobilizer is an electronic device fitted to an automobile which prevents the engine from running unless the correct key is present. This prevents the car from being hotwired after entry has been achieved.

The microcircuit inside the key is activated by a small electromagnetic field which induces current to flow inside the key body, which in turn broadcasts a unique binary code which is read by the automobile’s Engine Control Module (ECM). When the ECM determines that the coded key is both current and valid, the ECM activates the fuel-injection sequence.

The immobilizer function of the Infiniti Vehicle Immobilizer System (IVIS) or Nissan Anti-Theft System (NATS) consists of the following:

– NATS ignition key
– NATS antenna amp. located in the ignition key cylinder
– Body control module (BCM) or (IMMU)
– Engine Control Module (ECM)
– Security indicator lamp

Some of you may have seen this in a few other Maxima groups. I did a 350Z heated and power seat swap into my 2002 Maxima. I used the 350z seat rails and all. I cut the 350z mounts from the rails and bolted the rails to a set of aftermarket brackets. Used existing heated seat wiring in the Maxima. Also had to trim the side panels off the 350z seats. I gained around 2 inches of headroom. I love them. No more sliding around in the turns. That..and they look great.

This 2003 Nissan Maxima had a faulty blower resistor and as a result I wanted to look at the cabin air filter as a possible cause of the resistor failure. To see that repair please click here. The cabin air filter is located behind the glove box area and the glove box has to be removed. To do that the kick panel and rocker panel trim have to be removed. The plastic nut at the top of the kick panel will unscrew with just finger pressure.

The rocker trim panel has to be lifted at the rear edge and removed from its location.

With the rocker trim panel out of the way the passenger kick panel will now come out.

Removing the lower left glove box retaining screw.

Removing the lower right glove box retaining screw is the reason why the kick and rocker panels had to be removed.

There are a total of four screws that have to be removed along the upper edge of the glove box opening. Two in the center at the latch area and one in each corner.

Ease the glove box assembly down and detach the light assembly and the airbag connector from the glove box housing. there is no need to disconnect the airbag connector. If for some reason you decide to you must disable the airbag system according to the manufacturers instructions.

Finish removing the glove box assembly. The white vertical strip behind the glove box is where the cabin air filter is located.

There is a small spring clip located at the bottom of the filter cover. I used a small screwdriver inserted into the slot to flex and remove the clip.

Be careful not to lose this clip.

With the clip removed the white plastic strip will slide up. Then it can be pulled away from the box.

I slid the bottom filter out first and then the top.

There was good bit of debris that had gotten past the filters and I had to use a small hose attachment that I made for my shop vacuum to remove the debris.

Nice new filters being installed into the heater- a/c case.

The filters are marked with the word up and an arrow to indicate the desired installation direction.

This 2003 Nissan Maxima came in with the complaint that the passenger front window would go down on it’s own. What I determined was that when the window was raised up, it would automatically cycle down about six inches. If the glass, motor or regulator have been removed a relearn procedure is needed to restore proper operation.

The first step in this process it to remove the door panel. If you have already removed any of the listed parts you of course already know how to remove the door panel. Lift the screws cover in the door panel pull handle.

Then using a philip’s head screwdriver remove the single screw.

Lift and remove the switch trim panel.

There are retainers at both ends that have to be dealt with.

Remove the outer trim ring from the inside door handle.

You have to work along the inside edge of the ring to release the locking tabs.

Remove the screw cover at the front of the door panel.

Then the phillip’s headed screw.

I am pointing to the rest button on the power window motor.

To reset the upper and lower limits:

Make sure all switches are connected.

Turn the ignition switch on.

Raise the window fully. You may have to play with it to get it to stop at the full closed position.

Press and hold the reset switch.

While lowering the window fully. I am holding the switch with my unseen fingers. Kind of hard to hold the reset button, lower the window and take the picture all at the same time.

Release the reset switch. Make sure it pops back out.

Raise the window fully.

The limit switches are now reset.

Now the most important part of this procedure. If the door panel is already back on, the procedure can be done by only removing the switch cover and locating the reset switch button that I am pointing to with my screw driver. If you cannot reach the reset button with your fingers you should be able to with a large tipped common screwdriver.

In the process of installing my supercharger (which runs of alternator), I decided to upgrade my OEM alternator to a DC Power 270 Amp Alternator. The OEM alternator is 110 amps. I paid $300 bucks for the DC 270 Amp Alternator. They usually go for $600+ according to the DC Power website.

The DC Power alternator was a direct fit to my 2004 6thgen Maxima. The installation was also straight-forward. I also did the “BIG 3” and upgraded all the wires to 1/0 gauge. This included the grounds and charge wire. I upgraded my battery to a Northstar AGM31 as well (but will save that for another post).

Please keep in mind the factory cables weren’t designed to handle the power of a higher-output alternator, and can restrict the flow of electricity (or cause cables to fry up). The “BIG 3” upgraded is highly recommended.

NISformance is now offering the VQ35DE SSIM Gutted Manifold Service.

What is a SSIM? Originally innovated by SR20DEN (from its a stock VQ35DE upper intake manifold from 2002 2006 Maximas. Where the inside of the manifold shelf that splits the runners is removed. This has been proven to increase both horsepower and torque above 6000 rpm. A must have for making top end power. It does remove the stock vias so there are some low end losses between 2.5-4K rpm.

This is a SERVICE and you MUST send in parts! 


  • Upper Manifold and elbow SSIM = $150
  • Stock vias to block off plate = $10
  • Lower intake porting = $40

Why are we offering this service now? We have had many community members wanting us to do the service. We also offer lower intake manifold porting. We also have a few key benefits with our SSIM service.

  • Completely clean the manifold inside and out. This means when you receive your NISformance SSIM there are no shavings inside that need to be cleaned out (saves a lot of time during install).
  • We make sure there are no cracks in the manifold, as this can happen during removal, or damaged in shipping.
  • Mating surfaces are sanded and ready for installation either with oem gaskets, or gray RTV. That means no powder coating or paint all over the mating surface further saving you time during installation!
  • Throttle body coolant pipes are removed. This makes for a cleaner looking engine bay when bypassing the 2 coolant lines that go to the tb flange.
  • Block off plate, if you have a stock vias plate we can simply cut it and weld it up to make a block off plate. (saves money)
  • Porting on the intake runners

This how-to will walk you through installing a GS-100A flashing brake module on your 5thgen Maxima. You can buy them in different configurations depending how quick you want the module to flash. You will need 1 module for each taillight (they are usually sold in pairs). 

Model #: GS-100A
Price: $7.65-  $8.00 (comes with two modules)
Purchase Location: Available on eBay and Amazon (and many other online stores)


  • Installation is very easy, simply tap this controller module box in-between the brake light and the wiring harness and that’s it.
  • This LED flash strobe controller allow you to convert the vehicle brake lamp to quickly strobe for 3 times, then flash for 3 times and then constantly lighting up.
  • This strobe/flash feature can better alert the vehicle behind you to prevent any rear-end collision.

Installation Process

Step 1 – First you need to locate the brake light wire and the running light wire. On all 5th gen models (00 – 03), the brake wire it self is green with a yellow strip and running light wire is green with a white strip. You will want to cut the brake wire in half and splice off both ends.

Step 2 – Connecting the leads from the module into the brake light wiring itself. On the module you’ll notice that there is a 2 sets of red and black wires. One side is IN and the other side is OUT.

Step 3 – Connecting the wires. On the harness for the brake light you will want to splice into the ground wire (black) and connect both black wires from the module into the ground lead from the harness itself.

Step 4 – Connecting the IN and OUT red wire leads. The IN side of the module will connect directly to the harness side of the wire directly and the OUT side will connect to the bulb connector side of the 2 spliced wires mentioned in step 1.

Step 5 – Now apply black electrical tape to all connection where you either spliced into ( ground wire) or connecting spliced connections ( green w/yellow stripe wire ) and mount module in safe location. Once done the results should look like such:
