I have a DRS25AX installed with TZT12F display. I have a fault displayed as "No Radar" on the display. Checked the fuse and is good and have replaced just for troubleshooting purposes and no change. Have 24VDC up to the DRS25AX sensor connector.
On Radar Menu the source displays the correct sensor. The "Radar Monitoring" sub menu in the Radar settings displays blanks and no voltages are displayed. On the initial Set up settings "Sensor List" page the DRS25AX is not displayed now.
Appreciate your urgent assistance.
 
Last time I had someone with similar issues they had the voltage wires backwards. Have you verified the polarity of the power wires?
