The Four Main Advantages of A203

A203 can also display and monitor vehicle battery voltage, generator charging voltage, offering vehicle over speed alarm, high engine temperature alarm and monitoring and other functions. It even can read vehicle data streams, scan engine fault codes and offer fault code clearing functions.

1. Digital Display:
Display car speed, water temperature, engine rotation, instantaneous fuel consumption, hour fuel consumption, engine rotation progress bar display, coolant temperature

2. Car Performance Testing:
acceleration perfomance test, brake performance test, acceleration target speed test, initial braking speeds test

3. OBD2 Engine Diagnostic Functions:
Data flow function display, display color configuration, fault code scanning, fault code clearance and other functions. Car owners can scan and clear regular vehicle fault codes at their discretion and reduce repair costs without going to the 4S shop.

4. Early warning function:
Support multiple early functions: Water temperature warning, over speed warning, shift reminding early alarm and vehicle fault early alarm. Bring car owners great convenience for safe driving.

5. Feautes of product hardware
32-bit ARM CORTEX-M3 CPU, with 72MHz maximum operating frequency, in support of multiple high speed automotive communication protocols.

Specifications:

Operating voltage: 10-18V DC

Operating current: <80mA

Sleep current: <15mA

Operating temperature: -20~85 C

Product volume: 75mm*55mm*20mm


Speed meter indication error Speed Meter indicates speed and actual speed according to formula :
O ≤ Vn-VZ ≤ (V: + 10) + 4
V1- speed meter indicates speed in km/h;
V2- an actual speed in kilometers per hour (km/h).


The vehicle speed correction is based on 100km/h.

The error of the vehicle in the low speed state is the reason why the original vehicle meter is not linearly displayed.

Specifically, you can connect to the OBD socket test with a dedicated instrument in the 4s shop.

How to Install the A203
