Ancel A202 Automotive On-board Computer OBD HUD Display

1. Introduction

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.

2. Key Features

• Comprehensive Data Display: Shows Engine PRM, Coolant Temperature, Fuel Temperature, Battery Voltage, Engine RPM, Digital Speed, Driving Time, Driving Distance, Oil Temperature, Air-fuel Ratio, and Fuel Consumption.
• Diagnostic Capabilities: Read and erase engine fault codes (DTCs) and view data streams.
• Performance Testing: Includes Brake Test and Accelerator Test (SpeedUp Test).
• Early Warning Functions:
  • Speed Alarm: Customizable over-speed warning with visual and audible alerts.
  • Voltage Alarm: Alerts for low battery voltage.
  • Water Temperature Alarm: Notifies of high engine coolant temperature.
  • RPM Alarm: Shift warning based on engine RPM.
• Intelligent Reminder: Speed display color changes based on speed (0-99 White, 100-119 Yellow for reminder, 120+ Red for alarm).
• User-Friendly Interface: Digital display for easy readability, with simple button controls for mode switching and settings adjustment.

3. Compatibility

The ANCEL A202 supports all standard OBD2 cars. However, it is crucial to verify your vehicle's protocols before purchase as it does NOT support J1850 (J1850 PWM, J1850 VPM) protocols. Additionally, it is not compatible with Russian cars (VAZ, UAZ, LADA).

Specific Vehicle Exclusions:

• European Cars: Not supported if manufactured before 2004.
• American Cars: Not supported if manufactured before 2004 (e.g., Dodge, Jeep, Ford GM Chrysler, Chevrolet, Cadillac, Mustang, Lincoln).
• French Cars: Not supported (e.g., DS, Peugeot, Citroen, Renault).
• Japanese Cars: 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).
• Chinese Cars: Not supported if manufactured before 2008.
• Other Exclusions: Oil and electricity mixing vehicles, diesel-powered cars, Pick-up trucks, SUVs, and ORVs are generally not supported.

4. Setup and Installation

1. Locate OBD Port: Identify the OBD (On-Board Diagnostics) check port in your vehicle. This is typically located under the dashboard on the driver's side.
2. Connect Device: Insert the ANCEL A202 device into the vehicle's OBD port.
3. Connect Cable: Insert the other end of the provided OBD16pin to USB cable into the data interface of the A202 host.
4. Start Vehicle: Turn on your vehicle's ignition (or start the engine).
5. Establish Communication: 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.

5.3 Diagnostic Functions

Access the 'OBD diagnose' menu to perform the following:

• Scan DTCs: Read current Diagnostic Trouble Codes.
• Erase DTCs: Clear stored fault codes from the vehicle's ECU.
• Data Stream: View live data from various vehicle sensors.

5.4 Driving Tests

Navigate to the 'Driving test' menu for:

• SpeedUp Test: Measures acceleration performance.
• Brake Test: Evaluates braking performance.

6. Settings Configuration

The A202 allows for customization of various parameters to suit your vehicle and preferences. Access the 'Settings' menu to adjust:

• Engine Size: Set your engine's displacement (e.g., 1.5L, 2.0L).
• Fuel Type: Select between Gas or Diesel.
• OverSpeedSet: Configure the maximum speed threshold for the over-speed alarm.
• CoolantAlarm: Set the engine coolant temperature threshold for the high-temperature alarm.
• Shift RPM: Define the RPM level for the shift warning.
• SleepTimeSet: Adjust the time before the display enters sleep mode after the engine is turned off (default is 30 seconds).
• KPH Adjust %: Calibrate the speed reading for accuracy.
• VLT Adjust %: Calibrate the voltage reading for accuracy.
• LowVLT Alarm: Set the minimum voltage threshold for the low voltage alarm.
• Digit Cor: Change the color of the display digits/backlight.
• KPH Zero Set: Perform speed zero calibration.
• Fuel Adjust %: Calibrate the fuel consumption reading for accuracy.
• Sum Distance: View the total accumulated driving distance.
• Default Set: Reset all settings to factory defaults.

7. Troubleshooting

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.
