Sensor Tests


Sensor Functionality

Active Parking Assist

Over the years Imaging Systems Technology’s (IST) team of engineers have developed End of Line (EOL) test systems for Bosch, TTE (Tung Thih Electronics), Raytheon/Valeo and Allied brand ultrasonic park assist sensors. These brands of sensors are the most widely used in the industry and are installed in past and current models of GM, Chevrolet, Cadillac, Ford, Daimler, Toyota, Honda, Lexus, Nissan and Mitsubishi automobiles.



Active Parking Assist (APA) sensors, which are mounted in front and rear bumper fascia, use ultrasonic proximity detection to measure the distance between nearby objects and the vehicle. The system warns the driver with tones that indicate object distance. Since these sensors are mounted in front and rear fascia they are often referred to as Front Parking Assist (FPA) and Rear Parking Assist (RPA).
The IST Active Parking Assist Sensor Test System is designed to test harness continuity, sensor functionality and communications. In order to test the sensor functions, a target must be placed at a specific distance from each sensor to verify proper alignment and distance measurement. IST’s electrical and mechanical engineers have can design and install the fixtures needed to develop a complete testing and tracking system for your Active Parking Assist (APA) sensors. Our engineers have experience with a range of communication protocols used in the automotive industry such as KWP (Key Word Protocol), CAN (Controller Area Network) and LIN (Local Interconnect Network).
The IST Active Parking Assist Test System can easily be configured to account for distance and sensor range. Using the parts configuration masking feature of IST’s EOL Test Softwarethe system can test harnesses with differing numbers of sensors and lamps.
The IST EOL RPA/FPA Test Software saves all sensors measurement and communications status messages for each test that is run. Using the built in database features available in the IST EOL Test Software any part test can easily be viewed and verified.

Blind Zone Alert/Detection

Imaging Systems Technology (IST) has designed End of Line (EOL) test systems for a wide range of the industry leading radar sensors including Autoliv, Hella and Continental. These makers supply their sensors to automotive manufacturers including FIAT/Chrysler, GM, Chevrolet, Cadillac, Ford, Volvo, Daimler, Honda, BMW, Nissan and Kia.



Blind Spot Detection (BSD) and the Side Blind Zone Alert (SBZA) radar sensors help the driver safely pass other vehicles. The system uses two radar sensor modules that continuously monitor the presence, direction and speed of vehicles in the lanes around the vehicle. If a vehicle moves into the blind spot, a warning indicator lights up. If the driver doesn’t react to the indicator, an audio alarm goes off to provide additional warning.
The IST Blind Zone Alert Sensor Test System is designed to test harness continuity, sensor functionality, part revision, software revision, serial number and communications. IST’s electrical and mechanical engineers can design and implement a complete testing and tracking system for your Blind Spot Detection (BSD) and the Side Blind Zone Alert (SBZA) radar sensors. Our engineers have experience with a range of communication protocols used in the automotive industry such as KWP (Key Word Protocol), CAN (Controller Area Network) and LIN (Local Interconnect Network).
The IST Blind Zone Alert Sensor Test System can easily be configured to allow sensor hardware and software revisions. Using the parts configuration masking feature of IST’s EOL Test Software the system can test harnesses with differing numbers of sensors and lamps.
The IST EOL SBZA Test Software saves all sensor revision data and communications status messages for each test that is completed. Using the built in database features available in the IST EOL Test Software any part tested can be viewed and verified. The IST EOL SBZA Test Software saves all sensor revision data and communications status messages for each test that is completed. Using the built in database features available in the IST EOL Test Software any part tested can be viewed and verified.

Short Range Radar

Imaging Systems Technology (IST) has designed End of Line (EOL) test systems for a wide range of the industry leading radar sensors including Autoliv, Hella and Continental. These makers supply their sensors to automotive manufacturers including FIAT/Chrysler, GM, Chevrolet, Cadillac, Ford, Volvo, Daimler, Honda, BMW, Nissan and Kia.


The Short Range Radar (SRR) sensors use radar technology at 24 GHz to detect objects in front of or surrounding the vehicle. These radar sensors are used alone or in conjunction with Side Blind Zone Alert (SBZA) sensors for collision avoidance/mitigation systems. SRR sensors are also used in adaptive cruise control (ACC) systems to monitor the distance between vehicles and adjust the speed accordingly.
The IST Short Range Radar Sensor Test System is designed to test harness continuity as well as sensor functionality, part revision, software revision, serial number and communications. Our engineers have experience with a range of communication protocols used in the automotive industry such as KWP (Key Word Protocol), CAN (Controller Area Network) and LIN (Local Interconnect Network). IST’s electrical and mechanical engineers can aid you in designing and implementing a complete testing and tracking system for your Short Range Radar (SRR) sensors. Our engineers have created End of Line (EOL) test systems for the most widely used SRR sensors in the automotive industry, which are made by Autoliv. These sensors are used by OEM automotive manufacturers world wide including FIAT/Chrysler, GM, Ford, Volvo, Daimler, Honda, BMW, Nissan and Kia. Our engineers have experience with a range of communication protocols used in the automotive industry such as KWP (Key Word Protocol), CAN (Controller Area Network) and LIN (Local Interconnect Network).
The IST Short Range Radar Sensor Test System can easily be configured to account for sensor hardware and software revisions. Using the parts configuration masking feature of IST’s EOL Test Software the system can test harnesses with differing numbers of sensors and lamps.
The IST EOL SRR Test Software saves all sensor revision data and communications status messages for each test that is run. Using the built in database features available in the IST EOL Test Software, any part that has been tested, can be viewed and verified.

Hands Free Lift Gate

Imaging Systems Technology’s engineers have created End of Line (EOL) test systems for the Brose brand HFM which has become one of the top suppliers to OEM automotive manufacturers world wide including BMW, Mercedes-Benz, FIAT/Chrysler, Dodge, Ford, Volvo, General Motors, Chevrolet, Cadillac, Honda, Nissan, Volkswagen and Audi.


The Hands Free Lift Gate Module (HFM) utilizes two sensors located between the tailpipes to form an electronic field. When broken, the field activates the lift gate. Before the lift gate activates, the gate sensors must detect a shin, then a foot, followed by the shin leaving the sensor area followed by the foot. The distinct order of events helps the system avoid false lift gate triggers.
The IST Hands Free Lift Gate Module Test System is designed to test harness continuity as well as sensor functionality and communications. IST’s electrical and mechanical engineers design and implement a complete testing and tracking system for your Hands Free Lift Gate Modules (HFM). Our engineers have experience with a range of communication protocols used in the automotive industry such as KWP (Key Word Protocol), CAN (Controller Area Network) and LIN (Local Interconnect Network).
