How to Reset & Fix Forward Collision Warning (FCW) light | Pre-Collision System Light Flashing 

@@Airtouch67 Replacing the front collision warning sensor might resolve the MALFUNCTION error and light, but it's not guaranteed. The vehicle's system often requires calibration after sensor replacement to ensure accurate functionality. This calibration process typically involves specialized equipment and software that most dealerships possess. Therefore, it's likely you would still need to visit Nissan or a qualified technician to calibrate the sensor properly. This ensures that the system works correctly and safely.

@@Dashboardwarninglights Well I bought my Rogue brand new and honestly it's NEVER worked correctly. So basically it sounds like replacing the sensor is a waste of time. Nissan has this programmed so that you have to take it to them anyway.. $2000.00 for a part that costs $50 bucks on e-bay. Never buying a Nissan again. Lesson learned here. Apparently MILLIONS of Nissan owners get this Malfunction error, and Nissan is doing absolutely nothing to help resolve the issue.

@rustyshackleford4876 The forward collision warning system typically relies on sensors located in the front of the vehicle, separate from the lane-keeping assist (LKA) camera/sensor. While removing the LKA camera/sensor might affect other safety features like lane departure warning, it shouldn't directly trigger the forward collision warning light. However, it's best to consult your vehicle's manual or a mechanic for specific information about your car's system.

@user-ck5kp9dn3k I talked about this video in Steps Since you cleaned the camera and the light is no longer on, it suggests that the system is back to normal operation 👍

@ecoboostedfuze If the Forward Collision Warning (FCW) light turns on and the system disables after some time of driving, it could indicate a few potential issues: 👉 Sensor Blockage or Malfunction: The FCW system relies on sensors (often located at the front of the vehicle) to detect obstacles. If these sensors become blocked by dirt, debris, or snow, or if they malfunction, the system might initially work but fail as you drive. Checking and cleaning the sensors might resolve the issue. 👉 Overheating Sensors: In some cases, sensors might overheat, especially after prolonged use of the car. This could temporarily impair their function until they cool down. 👉 Electrical Issues: Fluctuations or faults in the vehicle’s electrical system could cause intermittent failures. This might be due to loose connections, aging wiring, or problems with the car’s onboard computer. 👉 Software Glitch: The system's software may have a glitch that causes it to shut down after a certain period of operation. A software update from the dealership could potentially fix this.

@GaryRobinson-sm8tz Since the problem persists even after the dealer has supposedly cleared fault codes, it's important to keep pressing them for a proper solution. Your idea about a faulty sensor could still be valid, even if they've told you the sensors are okay. Don't hesitate to ask for a thorough inspection and perhaps even request a second opinion if necessary. Your persistence will hopefully lead to a resolution.

Thanks for your prompt reply..Car has now been sitting at the dealers, for three days and not moved as I have a tracking on it..I have a fourth car but not fit for purpose as I can not get my sites mobility scooter in the boot..I now await a call and see what they have done..

That's ment to read a Hired car.

Update.after no contact from the dealer, I went there myself. And then told it's waiting for a part..What part I asked and was told , A forward lane sensor unit , the one in the windscreen.. I was told to expect the part next week..We shall see if it's this what's causing the problem. I still think it's the forward sensor behind the front Nisson badge..as both warning lights come on. And before I took the car to the dealers I had switched off the lane sensor and I still got the collision light on the dash

We wait ...

@jonitaite6800 Forward sensors are typically located at the front of a vehicle or machine and include various technologies such as radar, lidar, ultrasonic, and cameras. They are usually positioned in strategic locations like: Front Bumper: Common placement for radar and ultrasonic sensors for detecting obstacles and assisting in parking. Grille: Often houses radar sensors to aid in adaptive cruise control and collision avoidance. Windshield: Camera sensors for lane-keeping assistance, traffic sign recognition, and forward collision warning. Side Mirrors: Can contain cameras or sensors to cover blind spots and provide additional forward-looking coverage. Front Fenders: Sometimes used for side-facing sensors that still have a forward-looking component for detecting cross-traffic. These placements ensure that the sensors can effectively monitor the area in front of the vehicle or equipment to enhance safety and operational efficiency.

My brother wanted to reset the code for me by disconnecting the battery. And hook it back up. I would not let him. That would ruin any warranty I have! Even though I trying fight mine. But I think it’s dangerous in rain etc! Who knows! Dealership acted like it would be!

@sherrid5315 Right

Would disconnecting the fuse and just driving the car cause the fcw malfuntion light to go away? Or will it always be on if i unplug the fuse ? ​@@Dashboardwarninglights

@@killertofu Disconnecting the fuse will not make the FCW malfunction light go away. In fact, it will likely cause the light to stay on or trigger additional warnings. The vehicle's onboard computer will detect the loss of power to the FCW system and register it as a fault, keeping the warning light illuminated. To resolve the issue properly, you should change the fuse if it is faulty.

@Dashboardwarninglights the problem is my sensor is broke. I need to replace but I can't find he part anywhere or what it looks like. Do you by chance have a link to show what it looks like and where it's located on the car so I can buy a replacement
