The Rear View Radar is an object detection system that instantly detects any obstruction at the vehicle's rear, audibly alerting the driver to its presence and distance. It is often paired with an in-cabin monitor and rear camera for a complete backup camera solution.
This article is written to help users troubleshoot and resolve malfunctions in their Side View Radar Systems. If technical issues persist, please contact Pro-Vision technical support for further assistance.
| Problem | Possible Cause | Possible Solution |
| Constant Alerting | The sensor detects part of the vehicle or the ground. | Visually inspect the selected installation location for any possible obstructions. It may be necessary to relocate the sensors. |
| Test the detection zone and use the RadarTool application to reconfigure the detection zone if necessary. | ||
| Red X Over Camera Images on the Monitor | The radar sensor and control box are not communicating | Verify the sensor’s cable connections. Reconnect any loose or unplugged cables. |
| Check the color of the extension cable ends; CAN Bus Extension Cables should have red ends. | ||
| Verify that the sensor extension doesn’t exceed 20 m (65 ft). | ||
| Check the product labels on the sensor's cable (REV B), the back of its housing (REV A), and the top of the control box. Components are marked “REV B” in the bottom right corner of the label, and both should be of the same REV. | ||
| Check the connector cables for damage, starting with the Y splitter cable, and replace them if needed. | ||
| Check the radars for damage and replace them if needed. | ||
| Wrong or No Camera Image on the Monitor | Incorrect trigger wire configuration | Verify that the trigger wire is accurately connected to the control box. |
| The selected wire does not have the necessary signal | Test the wire with a digital multimeter. It should receive a constant +12 Vdc to +24 Vdc signal. | |
| The Monitor is not Alerting Audibly | The monitor’s volume isn’t on. | Turn the monitor’s volume on or up. Refer to the monitor’s guide if needed. |
| The system signal is not strong enough. | Test the wire with a digital multimeter. It should receive a constant +12 Vdc to +24 Vdc signal. |
