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.
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.
⚠️ Important: Always identify vehicle wiring by function using a digital multimeter. Do not rely solely on wire colors, as they may vary by model year, trim level, or market.
Nissan Models Commonly Installed
This guide applies to many mechanical-key Nissan vehicles, including:
Always confirm your vehicle uses a traditional key ignition before installation.
Before Installation
Before starting:
✅ Make sure the vehicle starts normally with the factory key.
✅ Confirm battery voltage is above 12V.
✅ Use a digital multimeter.
✅ Do not rely only on wire colors.
✅ Disconnect the battery before cutting ignition wires.
✅ Confirm whether the vehicle has a factory immobilizer.
⚠️ Never begin installation on a vehicle with existing electrical faults.
Understanding Nissan Ignition Circuits
Most mechanical-key Nissan vehicles may include:
Constant Battery Power
ACC
IGN1
IGN2
Starter
Some Nissan models may use additional ignition or accessory circuits.
💡 Always test each wire by function:
ACC: powered in accessory position
IGN1: powered in ON and START
IGN2: may drop during START depending on vehicle
Starter: powered only while cranking
Brake Input
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.
ACC Output — Blue Wire
The Blue ACC wire powers:
Radio
Navigation
Accessory circuits
If ACC is wrong, the car may still start, but accessories may not work correctly.
IGN1 Output — White Wire
The White IGN1 wire is one of the most important connections. It powers:
Dashboard
ECU / ECM
Engine management system
IGN1 must stay powered during cranking.
If IGN1 is wrong:
Dashboard may not turn on.
ECU may not power up.
Engine may not start.
IGN2 Output — Brown Wire
The Brown IGN2 wire may power:
HVAC
Blower motor
Additional accessories
Some Nissan vehicles cut IGN2 during cranking. Others may need it powered. Always verify whether the factory IGN2 stays powered or drops during START.
Starter Output — Yellow Wire
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.
Nissan Immobilizer / NATS System
Many Nissan vehicles use NATS — Nissan Anti-Theft System.
This is one of the most common causes of:
Engine cranks but does not start
Engine starts briefly and stalls
Security light flashing
Key not recognized
⚠️ If the vehicle has NATS, the transponder chip must be detected correctly, or a compatible bypass solution may be required. Do not keep changing ignition wires if the starter already cranks. At that point, the issue is often immobilizer-related.
BCM Considerations
Many Nissan vehicles use a Body Control Module to manage:
Door locks
Security
Interior lights
Keyless entry
Alarm signals
💡 When wiring lock/unlock or door trigger circuits, avoid guessing. Always verify whether the circuit is positive trigger, negative trigger, or BCM-controlled.
Bench Testing
Before installing the system into the vehicle, perform a bench test.
Connect:
Constant 12V power
Ground
START button
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.
Blue Status LED
Normal behavior:
Disarmed: LED OFF
Armed: slow flashing
Alarm triggered: fast flashing
So if the blue LED stays off during bench testing or before the system is armed, that is normal.
Remote Start Requirements
Remote Start requires all of the following:
✅ Parking brake input connected
✅ Fuel pump detection wire connected
✅ Vehicle locked
✅ Security mode armed
⚠️ If one condition is missing, Remote Start will not operate. If the horn beeps three times during remote start attempt, check the parking brake input first.
Fuel Pump Detection Wire
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.
Common Nissan Installation Problems
Button Only Cycles ACC / IGN
Brake input not detected. Check the brake switch output.
Dashboard Does Not Turn On
IGN1 wiring issue. Check the White wire connection.
Radio Does Not Work
ACC wiring issue. Check the Blue wire connection.
Starter Does Not Crank
Brake input missing, Yellow starter wire incorrect, or starter circuit not identified correctly.
Engine Cranks But Will Not Start
NATS immobilizer, transponder chip not detected, incorrect bypass solution, or key chip placed too far from antenna.
Confirm brake input before checking starter output.
If the engine cranks but does not start, check NATS first.
Verify lock/unlock circuits carefully because many Nissan vehicles use BCM-controlled signals.
Perform a bench test before cutting factory wiring.
