KOSO support FAQ

ఈ బ్రాండ్ కోసం మాన్యువల్లు, రిజిస్ట్రేషన్ మరియు మద్దతు గురించి సాధారణ ప్రశ్నలు.

  • Can I disassemble my KOSO gauge for maintenance?

    No. Opening or disassembling the unit yourself will void the warranty. Maintenance and repairs should only be executed by KOSO professionals.

  • What should I check if my KOSO gauge does not power on?

    First, ensure the wiring includes a solid ground and that the 12V power supply is connected. Check if the battery voltage is sufficient (at least DC 12V) and inspect the fuse and wiring harness for breaks.

  • How do I connect the Zenith LED Headlight wires?

    For the KOSO Zenith LED headlight, connect the Yellow wire to the Low beam, the Blue wire to the High beam, the White wire to the Front Position Light, and the Black wire to the vehicle body or engine ground.

  • What does 'LO RNG' mean on my KOSO digital gauge?

    'LO RNG' indicates that the remaining fuel range is low (typically under 16 km or 10 miles). This is a warning to refuel soon.

  • How do I enter the settings mode on my KOSO meter?

    Generally, you must have the key switched to ON, the engine stop switch OFF, and the meter displaying the Odometer. Then, hold both turn signal switches (or the specified button combination for your model) for 3 seconds to enter settings.
