Checklist Before Use - OBD
▶ For the OBD Ⅱ setting, the car must be fully started and MOTREX HUD APP must be
launched.
(Setting cannot be modified under ACC ON or KEY ON status.)
▶ Please reenter and save the car information after an OBD Ⅱ firmware or DB file update.
▶ Please check the information (year/fuel type/mileage) on the vehicle registration before
entering the car information on OBD Ⅱ.
(When using the car information (vehicle identification number) attached to the car, OBD
Ⅱ communication may not work properly.)
▶ Although the car model name is the same due to the manufacturer’s categorization by
model year, the cars actually supported may be different from the list of cars supported.
▶ There may be restrictions in functions depending on the car’s grade (trim) and
options.
▶ There may be restrictions in some functions (genuine trip setting) related to OBD Ⅱ
communication. In this case, the operation is only enabled under ACC ON status.
▶ OBD Ⅱ is not supported for a car with structural modification.
▶ For some hybrid cars and cars that use two types of fuel, the fuel efficiency information
may not match the actual measurement.
If necessary, please correct the fuel efficiency before use.
▶ For electric cars, the fuel efficiency option is disabled. Remaining gas is replaced with
the battery charge rate.
▶ Fuel efficiency and distance to empty may change according to the driving condition,
therefore, it may be different from the officially recognized value or the actual distance
traveled. If necessary, please correct the fuel efficiency before use.
▶ For some car models, the method of installation may be different.
▶ When more than 7 car DB has been registered on OBD Ⅱ, OBD Ⅱ will not work and
there will be no compensation. This does not apply if a same car is being registered
repeatedly.
▶ Vehicles not listed on the supported vehicle list (passenger standard, vehicles fitted with
standard OBD) should be used by setting the vehicle to OBD II Standard on other vehicles.
(It is limited to Hyundai and Kia vehicles.)
▶ When connecting an OBD II module using Y-CABLE, there may be errors in the function
and operation of the product.
▶ The OBD II module must be used with direct contact with the vehicle connector.
