A203 OBD2 Car Trip Computer description

ALicar A203 OBD mini car trip computer is a small carinstrument with powerful functions, which is especiallysuitable for vehicles without a tachometer, an enginetemperature gauge and fuel consumption display functions.

A203 can also display and monitor vehicle batteryvoltage, generator charging voltage, offering vehicle overspeedalarm, high engine temperature alarm andmonitoring and other functions. lt even can read vehicle data streams, scan engine fault codes and offer fault code clearing functions

A203 OBD2 Automobile Trip Computer installation and usage

Insert the product into the check port on the vehicle OBD computer, insert the other end of the produet into the data interface of the host.

After the product is inserted into the host and the car is started, wait for the communication linkage between A203 and the car, After the linkage issuccessfully established, the host will send a “'drop’sound, at the same the display screen displays vehicle protocols and then indicates that it is the first time the produet is used to set up parameters.

A203 Trip Computer installation preeautions:

The automobile instrument panel must be kept clean,if waxing is done with car instrumentwaxes, causing the double adhesive not to be pasted, please carry outcleaning operations with a heat towel and then undertake installation. When installation, heat the instrument panelby blowing air, which can achieve the best effects.

A203 OBD2 Car Trip Computer usage settings

Press the function key in the front of the host to enter into product menu status

Electronically Controlled Diagnosis System

Press the function key again to enter the electronically controlled system, The electronically controlled system contains three menu functions.

Enter fault code scanning functions to read car fault code information and choose whether to clear car faults.

Choose to read data streams to detect car data inreal time. Choose the key leftwards and rightwards to flippages up and down for query.

Car performance tests

Car performance tests include: accelerationperformance tests, brake performance tests, accelerationtarget speeds, and initial braking speeds

When an acceleration performance test is carried out,set up an acceleration target speed firstly, and finish the acceleration performance test after the set speed isreached. When the brake performance test is undertaken,it is necessary to set up an initial braking speed firstly;when the initial brake speed is reached, start to calculatethe brake distance until the car speed is stopped.

A203 OBD2 Car Trip Computer Instrument parameter settings

Choose instrument parameter settings, enter the instrument parameter setting interface, and adjust the parameter size left and right, long press the function keyto return to the previous menu.

Instrument parameter settings include the following setting class contents:

1. Engine displacement settings

Set up the engine displacement size, after this parameter is set, the car's instantaneous fuel consumption and average fuel consumption are accurately calculated.

2. Fuel type setting

Choose petro, diese1, diesel 2; in different diesel modes,fuel consumption data sees great changes.

3.verspeed alarm

Set up this parameter, when the set car speed is reached, the instrument will send "drop.drop" sounds to give an alarm, the car speed text will display in red.

4. High water temperature alarm

Set up thisparameter, when the engine reaches the alarm temperature instrument, “drop, and drop" sounds will be given, at the same time the displayed temperature character is red.

5.Shift reminding rotation speed

After this rotation speed is set, shift reminding status is reached, and a shift prompt tone will be sent, at the same time , shift characters display

6. Shift reminding upper limit

The car speed reachesthe set value, the shift reminding will be shut down, incase there are no gears to uplift at the highest gear afterthe set car speed is exceeded.

7.Instrument standby time

After the car flames out,the set value is reached, and A202 will sleep automatically.

8.Car speed error correction

When the car speed meter displays 100 km status, adjust A202 display to bein accordance with the car speed meter.

9.Battery voltage correction

Correct voltage display accuracy settings in A202

10.Alarm voltage settings

 Set up this parameter to remind car owners whether the battery is damaged.

11.Instrument digit color

Seven colors are available for option, users can carry out settings based on their preference.

12. Car speed reset settings

In idle modes, if the car speed is lower than the set value, the car speed will be displayed as zero.

13.Fuel consumption data correction

lf there is an error between average fuel consumption displayed in A203 and actual fuel consumption, adjust this parameter, If the displayed fuel consumption is bigger than the actual one, decrease the percentage, otherwise increase the percentage.

14. Factory reset settings

Choose this function to restore A203 data to initial status.

A203 OBD2 On-board Computer Information

The product information function can query product software versions and communication protocols of this car as well as help and solutions to car compatibility problems.

A203 OBD2 Car Trip Computer on car compatibilities

A203 Trip Computer can be used on most of cars normally through plug and play.

When used in some cars, car dashboard lights or faul talarm lights are caused to be lit up abnormally, operate according to the help hint on compatibility solutions and use needle-nose pliers to twist off excess pins to eliminate such phenomena.
