      Thomas GarzaAug 4, 2025
      Your Denso Accessories unit might not be working because: 1) The unit was switched on and off repeatedly. To resolve this, switch the unit off and wait at least 10 seconds before restarting it. 2) External unit fuses are blown. If this is the case, replace the fuses. 3) Internal unit fuses are blown. Replace the internal fuses to fix this.
