1. Introducció
The ANCEL A202 OBD mini car trip computer is a compact and powerful instrument designed to enhance your driving experience by providing crucial vehicle data. It is particularly useful for vehicles that lack a built-in tachometer, engine temperature gauge, or fuel consumption display. The A202 offers real-time monitoring of various parameters, including battery voltage, generator charging voltage, and provides essential alarms for over-speeding, high engine temperature, and shift points. Additionally, it functions as an OBD2 scanner, capable of reading vehicle data streams and diagnosing/erasing engine fault codes.

- American Cars: Not supported if manufactured before 2004 (e.g., Dodge, Jeep, Ford GM Chrysler, Chevrolet, Cadillac, Mustang, Lincoln).
- French Cars: No compatible (per exemple, DS, Peugeot, Citroën, Renault).
- Cotxes japonesos: Not supported if manufactured before 2008 (e.g., Suzuki, Mazda, Toyota, Honda, Mitsubishi, Subaru).
- Korean Cars: Some models manufactured before 2007 are not supported (e.g., KIA, Hyundai).
- Cotxes xinesos: No compatible si fabricat abans del 2008.
- Altres exclusions: Oil and electricity mixing vehicles, diesel-powered cars, Pick-up trucks, SUVs, and ORVs are generally not supported.

4. Configuració i instal·lació
- Localitza el port OBD: Identify the OBD (On-Board Diagnostics) check port in your vehicle. This is typically located under the dashboard on the driver's side.
- Connectar el dispositiu: Insert the ANCEL A202 device into the vehicle's OBD port.
- Connectar el cable: Insert the other end of the provided OBD16pin to USB cable into the data interface of the A202 host.
- Inici del vehicle: Turn on your vehicle's ignition (or start the engine).
- Establir comunicació: Wait for the communication linkage between the A202 and the car. Once successfully established, the host will emit a "drop" sound, and the display screen will show vehicle protocols. This indicates the device is ready for initial parameter setup.

7. Solució De Problemes
Q1: Why does the device automatically turn off after a period of time?
A1: The default sleep time for the ANCEL A202 is 30 seconds. If your engine is turned off, the device will automatically power down after this duration. To change this, navigate to the 'Settings' menu and adjust the 'Sleep Time Set' parameter to your desired duration.
Q2: Why are my car dashboard lights or fault alarm lights lit up abnormally after connecting the device?
A2: In some specific vehicle models, connecting the A202 may cause abnormal illumination of dashboard lights or fault alarms. To resolve this, go to 'Product inf' > 'Matching inf' on the device. This section provides specific solutions, which may include using needle-nose pliers to cut off pins 7 and 15 of the OBD2 connector to eliminate such phenomena. Refer to the pinout diagram in Figure 7 for pin identification.
