Complete wiring, NATS immobilizer bypass, BCM considerations, and troubleshooting for Altima, Maxima, Sentra, Rogue, Pathfinder, Frontier, Titan, and more
Nissan vehicles are popular platforms for aftermarket push button start upgrades, especially models such as the Altima, Maxima, Sentra, Versa, Rogue, Pathfinder, Frontier, Titan, Murano, and Xterra.
The EFHIPS Universal Push Button Start System can add push button start, keyless entry, remote start, and anti-theft functions to many Nissan vehicles equipped with a traditional mechanical key ignition system. For a complete step-by-step installation walkthrough, see our main installation guide which covers the general process in detail.
However, Nissan vehicles often use factory immobilizer systems, BCM-controlled circuits, and different ignition layouts depending on the model year and trim level. Before installation, every circuit must be verified by function using a digital multimeter. If you're new to automotive wiring, start with our beginner-friendly installation guide before working on your Nissan.
This guide applies to many mechanical-key Nissan vehicles, including:
Always confirm your vehicle uses a traditional key ignition before installation. Not sure if your car qualifies? Read our guide on How Do You Know If Your Car Is a Good Candidate for a Push Button Start Kit?
Before starting:
Most mechanical-key Nissan vehicles may include:
Some Nissan models may use additional ignition or accessory circuits.
The brake input is critical.
If the EFHIPS brake input wire is not connected correctly, the START button will only cycle ACC → IGN1 → IGN2. The engine will not crank.
Most Nissan vehicles use a positive +12V brake signal when the brake pedal is pressed, but always verify with a multimeter. If the brake signal is negative, a relay conversion may be required.
The Blue ACC wire powers:
If ACC is wrong, the car may still start, but accessories may not work correctly.
The White IGN1 wire is one of the most important connections. It powers:
IGN1 must stay powered during cranking.
If IGN1 is wrong:
The Brown IGN2 wire may power:
Some Nissan vehicles cut IGN2 during cranking. Others may need it powered. Always verify whether the factory IGN2 stays powered or drops during START.
The Yellow wire controls the starter motor. If this wire is not connected correctly: Starter will not crank. Engine will not turn over. Some Nissan vehicles may have more than one starter-related circuit. Confirm with a multimeter before connecting.
Many Nissan vehicles use NATS — Nissan Anti-Theft System.
This is one of the most common causes of:
Many Nissan vehicles use a Body Control Module to manage:
Before installing the system into the vehicle, perform a bench test.
Connect:
Press the START button. If the internal relays click, the module, relay control, and button communication are working.
The small blue 2-pin LED is not a power indicator. It is only a security status LED.
Normal behavior:
So if the blue LED stays off during bench testing or before the system is armed, that is normal.
Remote Start requires all of the following:
For a broader overview of remote start installation, see our universal 2-way remote start system guide. And if you're weighing whether remote start is worth the effort, read about the five real-life benefits of remote start after installation from actual drivers.
The fuel pump detection wire helps the EFHIPS system judge whether the engine has started successfully. If connected incorrectly, the system may attempt to start the vehicle up to three times and then stop.
For a general approach to diagnosing push start installation failures across all makes, see our troubleshooting guide which covers the most common issues and how to fix them.
No. Some may not, but many Nissan vehicles with NATS require the transponder to be recognized before the engine can run. If you're concerned about safety, read Is a Push Button Start Kit Safe? Here's What Most DIY Installers Get Wrong.
Most likely the NATS immobilizer is not recognizing the transponder chip or bypass module. This is one of the most common Nissan-specific issues.
Brake input is likely missing. Verify the brake switch output with a multimeter.
Yes. A relay click after pressing the START button indicates the module is responding.
It is not a power indicator. It only flashes when the alarm/security system is armed.
Many owners find that upgrading an older Altima, Maxima, or Sentra with push button start makes the car feel significantly more modern.
