The Rear View Radar instantly detects any obstruction behind the vehicle and audibly alerts 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 Rear View Radar. 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. |
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. |
| Red X Over Camera Image on the Monitor | The radar sensor and control box are not communicating. |
a. Verify the sensor’s cable connections. Reconnect any loose or unplugged cables. b. Check the color of the extension cable ends; CAN Bus Extension Cables should have red ends. c. Verify that the sensor extension doesn’t exceed 15 m (50 ft). d. Check the product labels on the sensor (on the cable for REV B or the back of its housing for REV A) and the top of the control box. Both the sensor and the control box should be on the same REV. e. Check the connector cables for damage, starting with the splitter cable, and replace them if needed. f. Check the sensors for damage and replace them if needed. |
| Wrong or No Camera Image on the Monitor | Incorrect trigger wire configuration | a. Verify that the trigger wire is 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 +12 Vdc to +24 Vdc signal when the vehicle is in reverse. | |
| The Monitor is not Alerting Audibly | The monitor’s volume isn’t on. | a. Turn the monitor’s volume on or up. Refer to the monitor’s guide if needed. |
| The system signal is not strong enough. | a. Test the reverse trigger wire with a digital multimeter. It should receive a constant +12 Vdc to +24 Vdc signal when the vehicle is in reverse. |
