Is there battery voltage?

YES -Faulty driver's MICU, substitute a known-good driver's under-dash fuse/relay box and recheck

NO -Check for an open in the BRN wire between the driver's under-dash fuse/relay box and the gauge control module, or check for a poor connection between terminal No 17 and body ground (G401), and/or terminal No 1 and body ground (G402) If the fuse blown, repair a short in the wire between the driver's under-dash fuse/relay box and the gauge control module
