01 QUICK TROUBLESHOOTING

Radio values are chip/test references; final maximum radiated ratings remain unverified.
Park before checks. Use a competent installer for electrical tests; isolate gauge power before handling wiring/connectors.

02 MISSING READINGS

Available data varies by vehicle and ECU. A successful
connection does not mean every parameter is supported or
that every reading will be available.
A missing, blank or unavailable reading can mean the vehicle
does not supply that value, its operating conditions have not
been met, or fresh data has not arrived. Do not treat an
unavailable value as zero.
If other readings update, one missing value does not by itself
mean a fault. If values freeze or conflict with the original
instruments, stop relying on them and investigate. Always obey
the vehicle's instruments and warnings.

03 LONG-TERM PARKING

Check the gauge switches off after ignition-off and any
accessory delay. An ignition-switched gauge supply does not
switch off the vehicle's OBD socket.
For extended parking or storage, unplug the included ELM
adapter with ignition off, unless its low-power sleep behaviour
has been confirmed for your exact adapter and vehicle. An
adapter left powered can contribute to battery drain; there is no
universal safe parking duration.
Before the next use, refit the adapter securely with ignition off,
clear of pedals and your legs. Switch ignition on and allow
reconnection. If connection fails, follow the checks above.

What you see VS What to check

  • NO POWER / BLACK SCREEN

    Check ignition is on. Have the installer check the gauge-branch fuse, switched +12 V, ground
    and converter output. With power isolated, check USB-C and both labelled screen connectors
    are fully seated.

  • LOGO KEEPS PULSING

    First use: allow up to 3 minutes; later starts normally reconnect in under 30 seconds. The pulsing
    Ghost logo means connecting. Check ignition and adapter seating/power; close phone OBD
    apps. If needed, switch ignition off, reseat the adapter and restart once. Still stuck? Contact
    support.

  • SOME READINGS MISSING

    SOME REASee the explanation below. Check whether other live readings are updating. If none update,
    check the adapter connection. Some values need the engine running; only test this outdoors in a
    safe, ventilated location.

  • RESTARTS / CONNECTION DROPS

    Have the installer check for loose power, ground, USB-C or screen connections and voltage
    dips. Check the adapter is secure. Do not change wiring with power on or fit a larger fuse to
    mask a fault.

  • GAUGE STAYS ON WHEN PARKED

    Allow for the vehicle's accessory shutdown delay. If the gauge remains on, the feed may be
    permanently live. Have the installer verify and correct the switched feed. The OBD2 adapter is
    powered separately.

  • FUSE BLOWS / DAMAGE / HEAT

    Stop using the kit for repeated fuse failure, damage, unusual heat, burning smell or smoke.
    Isolate power safely and contact the installer or support. Never bypass the fuse, increase its
    rating or open either enclosure.
