Introduction
Welcome to MPC! In this video, we will guide you through the process of installing a remote start in a 2015 to 2020 Nissan Murano. Although the vehicle shown in this video is a Nissan Maxima, the wiring and programming procedures are identical. The only difference lies in the slightly different disassembly procedure. So let's get started!
Tools and Equipment Needed
Before we begin, make sure you have the following tools and equipment ready:
- Screwdriver (Philips)
- Pry tool
- Wire cutters
- T-tap connectors
- Spade connector terminals
- Remote start kit (including ECU and wiring harnesses)
- Flash link software
Disassembling the Nissan Murano
The first step is to disassemble the Nissan Murano to gain access to the BCM (Body Control Module). Start by releasing the tilt lock at the bottom of the steering wheel column and lowering the steering wheel down. Then, remove the top panel above the instrument cluster by pulling it up and out. Next, locate and remove the screws at the top and sides of the instrument cluster. Turn the steering wheel to the left and right to remove the screws on each side of the steering column. Use a pry tool to loosen the small panels on each side and the top of the steering column cover. This will allow you to remove the instrument cluster and cover for the top of the steering column.
Accessing the BCM
Now that we have removed the necessary panels, we can access the BCM. Remove the three screws that hold the instrument panel cluster in place. The instrument cluster will come out tilted forward. Disconnect the two plugs by pressing on the release tabs and pulling gently. Set the cluster aside. You will now see the ECU (Electronic Control Unit) behind the instrument cluster. Remove the screws on each side to release the ECU. Rotate it downwards to access the five plugs at the back. Press on the release tabs of each plug to disconnect them from the ECU. Leave the plug on the left side in place as we will be putting T-taps on two of the wires - the black and white wires as indicated on your tip sheet.
Wiring the Remote Start
Locate the black female 4-pin connector included with your kit. This connector has a black wire and a red wire with bare ends attached. Attach male Spade connector terminals to the ends of those wires. Plug the black wire into the T-tap on the black wire in the car and the red wire into the T-tap on the white wire in the car. This will provide power and ground to the remote starter. Now, it's time to plug in the wiring harnesses. Start with the green one and connect the female end into the matching green plug in the car. Insert the male end into the ECU. Repeat this process for the black plug next to it and the other two plugs. The set of white plugs is not used, so you can either cut the plug off and tape off the wires or stow it behind the dash with the rest of the wiring.
Programming the ECU
With the wiring complete, it's time to program the ECU using the Decrypter. Begin by connecting the 4-pin black connector with the locking tab from the Evo module to the corresponding 4-pin female connector with the red and black wires that were previously connected at the BCM. Then, plug the other 4-pin black plug (without the locking tab) into the Evo module while holding down the program button. The LED lights on the Evo module will start to cycle. Release the button when only the blue LED is lit. If a different LED is lit, disconnect the black plug and start over. Insert the remaining plugs into the Evo module - the 20-pin white connector, the 5-pin white connector, and the 6-pin red connector. Press the push-to-start button on the dash twice. The blue LED will turn off and then, after a few seconds, it will start to flash rapidly. Press the push-to-start button one more time. The blue LED will turn off, and the red and yellow LEDs will start to flash.
Decrypter Programming
Disconnect all the plugs from the Evo module, starting with the 4-pin black plug. The module is now ready for Decrypter programming. Make sure you have downloaded the flash link software, installed it, and updated your flash link light. Bring the Evo module to your computer and plug it into the 4-pin plug from the flash link light. Open the Decrypter tab in the software and click the send data button. Wait for the updater to read data from the Evo module and update it. Once it reaches 100%, the Decrypter process is complete. Unplug the Evo module from the computer and plug it back into the connectors in your vehicle.
Testing the System
Reinsert all the connectors into the Evo module, starting with the black 4-pin plug. Test the system by pressing the lock button on your remote fob three times, with each press about one second apart. After a few seconds, the car will start. Enter the vehicle and test to make sure it shifts into gear properly. Then, press the push-to-start button one time to shut the system down.
Reassembling the Nissan Murano
Now it's time to put everything back together. Stow the wires neatly and put the ECU back into place. Replace the Phillips screws to secure it. Insert the plugs into the back of the instrument cluster and replace the three screws that hold it in place. Replace the cluster trim panel and the top cover for the steering column. Secure them with the Phillips screws on either side of the front of the steering column. Finally, snap the top panel back into place. Test the system again to make sure everything is working correctly. Congratulations, you can now enjoy the convenience of a remote start in your Nissan Murano!
