Yes, a FIXD sensor can be used on multiple cars as long as each vehicle is a 1996 or newer model year gasoline-powered car or light truck sold in the United States. This broad compatibility is due to the standardized OBD-II (On-Board Diagnostics) port, which is mandated in all such vehicles. The FIXD device itself is just a hardware sensor; the real limitation is with the accompanying smartphone app, which allows you to create and manage separate profiles for each car you scan.

The process is straightforward. You plug the single FIXD sensor into the OBD-II port of the first car, open the FIXD app on your phone, and connect via Bluetooth. The app will recognize the vehicle and allow you to save its profile (e.g., "2015 Honda CR-V"). To use it on another car, you simply unplug the sensor, plug it into the second vehicle's OBD-II port, and either select the existing profile for that car or create a new one. The app can store an unlimited number of vehicle profiles, making it ideal for families or individuals with several cars.

However, a key limitation involves the FIXD Premium subscription. While the sensor hardware works universally, the premium features—like check engine light code descriptions, repair estimates, and maintenance reminders—are tied to a single vehicle. If you want these advanced diagnostics for a second car, you would need to purchase an additional subscription for that vehicle profile.

Vehicle Compatibility Factor	Details	Data Point / Example
Model Year Compatibility	Works with gasoline-powered cars and light trucks model year 1996 and newer.	1996 Toyota Camry, 2023 Ford F-150
OBD-II Port Location	The port is typically found under the dashboard near the driver's knees.	Common in vehicles from over 30+ manufacturers.
Diesel Vehicle Support	Generally not compatible with most diesel-powered vehicles.	Excludes many diesel trucks like a 2018 Ram 2500.
Motorcycle/EV Support	Not designed for motorcycles or fully electric vehicles (EVs).	Will not work on a Tesla Model 3 or Harley-Davidson.
App Vehicle Profiles	The FIXD app supports creating and saving an unlimited number of vehicle profiles.	A single sensor can monitor a family's 3-car fleet.

What is the purpose of prohibiting other vehicles from entering dedicated lanes?

Other vehicles are prohibited from entering dedicated lanes to ensure the normal passage of dedicated vehicles. Here is more information about dedicated lanes: Definition: Dedicated lanes refer to lanes designated for specific types of vehicles or specific purposes; Dedicated lanes can be categorized into pedestrian lanes, non-motorized vehicle lanes, and motor vehicle lanes. Advantages: Setting up bus-only lanes is significant for encouraging public transportation use, optimizing limited road resources, and alleviating traffic congestion. It also helps raise public awareness of public transit priority, prompts government attention to public transit priority, and lays the foundation for implementing public transit priority strategies in major cities in China. Hazards of occupying dedicated lanes: Delays in emergency response: Occupying emergency lanes hinders vehicles performing urgent tasks, such as rescue operations, from reaching accident sites promptly to handle incidents, mitigate hazards, direct traffic, or provide medical aid. This can worsen road congestion and even lead to fatalities due to delayed medical treatment. Aggravates road congestion. Increases the likelihood of accidents. Sets a negative example.

What is the normal temperature range for truck axle hubs?

Truck axle hubs normally operate within a temperature range of 100-200 degrees. Below are relevant explanations: 1. Axle Hub: In industrial equipment, the axle hub refers to both ends of an axle. An axle is a mechanical component, typically a metal cylindrical rod with varying diameters along its length, that supports rotating parts and transmits motion, torque, or bending moments. The rotating components in machinery are mounted on axles, with their end sections commonly referred to as axle hubs. 2. Causes: Overheating of wheel hubs (axle hubs) usually results from excessively tight bearing assembly or inadequate lubrication. Excessive temperatures can melt the grease inside, compromising braking performance, and in severe cases, may lead to bearing failure.

What products can be installed on the OBD port?

Products that can be installed on the OBD port include car computers, navigation devices, rearview cameras, and 360-degree panoramic imaging systems. Below is additional information: 1. Benefits of connecting to the OBD diagnostic port: External devices only read data from the car computer via the OBD port and cannot write data, making it very secure. The OBD has protection, and writing data requires password matching, making illegal intrusion nearly impossible. 2. Disadvantages of occupying the car OBD port: External electronic products may affect the car itself through the OBD port due to their own malfunctions or instability. For example, if the external electronic products are of poor quality, such as excessive power consumption or poor quality leading to short circuits, they can burn out the OBD port. If the standby current is too high, it can drain the car battery, making it impossible to start the vehicle. Therefore, products connected to the OBD must be of high quality.

What are the benefits of modifying a car's exhaust system?

Modifying a car's exhaust system is primarily done for aesthetic appeal and sound enhancement, such as altering the mid and rear sections. Secondly, it can involve adjusting exhaust backpressure and reprogramming the ECU to improve performance. Thirdly, some modifications are purely for visual appeal, focusing on the exhaust tips. Here is more detailed information: 1. Modifying only the exhaust backpressure: Changing only the exhaust backpressure to a straight-through design can increase the upper limit of the engine's net power output at high RPMs. However, the improvement is not significant, typically ranging from 5% to 10%. Essentially, this modification recovers the power lost due to the factory exhaust backpressure, but the effect is only noticeable at high RPMs. 2. Modifying backpressure along with ECU reprogramming: This approach marks the entry into serious performance modifications. Reprogramming the ECU can increase net power output, and when combined with reduced backpressure, it further expands the range of net power output, leading to a more substantial improvement in the vehicle's performance.

Is it mandatory to install a dash cam in the car?

There is no mandatory requirement for dash cams, so you don't have to install one. Here is more relevant information: 1. Benefits of installation: A dash cam can continuously record driving footage, which can be useful in cases of scratches, fraud, or traffic accidents. It can serve as evidence for traffic police to determine responsibility. If you want to avoid getting entangled in traffic disputes, it is recommended to install a dash cam. 2. Steps to install a dash cam: Remove the rearview mirror casing, detach the rearview mirror, slide the two metal clips downward, disconnect the rearview mirror cable after removing the casing, unplug the connector for the anti-glare rearview mirror, disassemble the dash cam mount, align the metal clips on both sides of the dash cam mount with the slots on the rain sensor mount, and push evenly upward on both sides until it slides to the bottom.

What is the technique for kick-activated trunk opening?

The method to activate the sensor-based power tailgate is to perform a kicking motion beneath the sensor, which can generally be divided into two types: the straight kick and the sweeping kick. The details are as follows: 1. Kicking motions: (1) Straight kick: Lift your foot from the ground to about 20 centimeters below the bumper sensor, allowing the sensor to recognize the kicking motion. (2) Sweeping kick: Lift your leg and sweep it horizontally beneath the sensor to trigger the power tailgate switch. 2. Principle: The kick-activated power tailgate, also known as the sensor-based power tailgate, allows the trunk to be opened hands-free through sensor activation. The principle behind the kick-activated power tailgate involves analyzing signal changes from two antennas installed at different positions to trigger the power tailgate switch.
