Side View Radar: Troubleshooting

The Side Radar instantly detects any obstruction at the vehicle’s sides and alerts the driver. It is often paired with an in-cabin monitor and side cameras, providing visual and audible alerts from the system's monitor. 

This article is written to help users troubleshoot and resolve malfunctions in their Side View Radar. If technical issues persist, please contact Pro-Vision technical support for further assistance.
 

Alerting Malfunctions

Problem Possible Cause Possible Solution
Constant Alerting The sensor detects part of the vehicle or the ground.

a. Visually inspect the selected installation location for any possible obstructions. It may be necessary to relocate the sensors.

b. Test the detection zone, and use the RadarTool application to reconfigure it if necessary. 

LEDs Not Activating Disconnected LED a. Verify the LED connection to the power harness and side radar control box. Reconnect any loose or unplugged cables 
Damaged LED a. Check the LED for damage. Replace the LED if needed.
Incorrect LED Activating The LED Indicators were incorrectly installed or wired a. Swap the LED connections on the power harness.
The vehicle's turn signal wires were installed incorrectly a. Swap the connection of the turn signal connections
The sensors are installed on the opposite side of the vehicle a. Uninstall, swap, and reinstall the sensors in the correct location.
LED Activating but Not Flashing The LED is not receiving a strong enough signal. a. If the LEDs’ wires were extended, verify that the circuit is still receiving a signal at the end of the extension. Shorten the extension as needed.
The Control Box is not being triggered.

a. Verify the trigger wires are securely connected.

b. Verify the selected circuits are active when expected.

 

Monitor Malfunctions 

Problem Possible Cause Possible Solution
Red Box Over Camera Images on the monitor The sensors and the control box are not communicating.

a. Verify the sensor cable connections. Reconnect any loose or unplugged cables.

b. Verify that both Ohm terminators are installed.

c. Check the color of the extension cable ends; CAN Bus Extension Cables should have red ends.

d. Verify that the extension between the sensors doesn’t exceed 20 m (65 ft).

e. Verify that the cable length from the sensors to the control box doesn’t exceed 25 m (82 ft).

f. Check the connector cables for damage, starting with the splitter cable. Replace any damaged cable.

g. Check the sensors for damage and replace them if needed.

Wrong or No Camera Image Incorrect trigger wire configuration a. Verify that the trigger wires are accurately connected to the control box.
The selected wire does not have the necessary signal a. Test the wire with a digital multimeter. It should receive a constant or intermittent +12 Vdc to +24 Vdc signal when the turn signals are active. 
The Monitor’s Indication Bar Displays on the Incorrect Side The sensors are mounted on the incorrect sides of the vehicle.   a. Physically uninstall and reinstall the sensors in the correct position.
The Monitor is not Alerting Audibly. The monitor’s volume isn’t on.  a. Turn the monitor’s volume on or up. Reference the monitor’s guide if needed.
The system signal is not strong enough. a. Test the turn signal trigger wires with a digital multimeter. It should receive a constant or intermittent +12 Vdc to +24 Vdc signal when the turn signals are active.
