If your JRC GPS unit isn't powering on, there could be several reasons. First, check the cabling from the junction box to ensure power is being supplied. Also, verify the power supply unit cabling if you're using optional power supply equipment. If the cabling is fine, inspect the fuse connected to the power cable and the fuse in the optional power supply equipment, replacing them if blown. If none of these steps work, the display unit switch might be broken, in which case you should consult with JRC or an affiliate.

If your JRC GPS isn't receiving a signal from the sensor, the issue might be a cut sensor connection cable, so check the cable. If the cable is not the problem, the sensor itself may be broken, and you should consult with JRC or an affiliate.

If your JRC GPS is not receiving data from external devices, the polarity of the serial cable might be incorrect, so check it.

The configured channel might also be incorrect; refer to section 4.20. If these settings are correct, the DISP-DPU or connector board might be broken, and you should consult with JRC or an affiliate.
