4. Setup

Before using your Autel MaxiSys Ultra, ensure proper setup for optimal performance:

1. Charge the Tablet: Connect the MaxiSys Ultra tablet to the power adapter and charge it fully before first use.
2. Connect VCMI: Plug the VCMI into the vehicle's OBD-II port. Ensure a secure connection.
3. Pair VCMI with Tablet: The VCMI connects wirelessly to the tablet via Wi-Fi. Follow the on-screen prompts on the tablet to establish the connection.
4. Initial Software Setup: Power on the tablet and follow the guided setup process, including language selection, Wi-Fi connection, and software updates. Ensure your software is up-to-date for the latest vehicle coverage and functions.

5. Operating Instructions: Performing a Relative Compression Test

The Autel MaxiSys Ultra, with its integrated oscilloscope and VCMI, simplifies complex diagnostic procedures like the relative compression test. This test helps assess the mechanical health of an engine by measuring the amperage draw from the starter during cranking.

5.1. Test Preparation

1. Identify Battery Location: Locate the vehicle's battery, typically in the engine compartment.
2. Connect Oscilloscope Leads: Connect one end of the oscilloscope lead to Channel A on the VCMI and the other end to a large dolphin clip (red). Connect the red clip to the battery's positive (+) terminal.
3. Connect Current Clamp: Connect the 650A AC/DC current clamp to Channel B on the VCMI. Clamp the current clamp around the battery positive wire. Ensure the current clamp is switched ON and set to the 1mV/1A range. Press ZERO on the clamp before the test.
4. Disable Fuel System: To prevent the engine from starting during the test, disable the vehicle's fuel system (e.g., by pulling the fuel pump fuse or relay).
5. Ensure Battery Health: Verify the battery is in good condition using a battery tester (e.g., Autel BT608). If the vehicle has multiple batteries, isolate one for the test to ensure accurate readings.

5.2. Tablet Operation

1. On the MaxiSys Ultra tablet, select the 'Measurement' application.
2. Choose 'Oscilloscope'.
3. Select the car icon at the top of the screen.
4. Navigate to 'Engine Starting' > 'Starter' > 'Starting Current/Voltage (TDV)'.
5. The tablet will display connection guidance and test kit requirements. Review these to ensure correct setup.
6. Press 'Start' on the tablet to begin recording data.

5.3. Performing the Test

1. With the fuel system disabled, crank the engine for a few seconds. The tablet will wirelessly capture the voltage and amperage waveforms.
2. Observe the waveform on the tablet. The red line represents voltage, and the green line represents amperage.
3. Use the buffer controls at the bottom of the screen to review the captured waveform.
4. Utilize the measurement tools (e.g., cursors) to analyze the peak-to-peak amperage draw for each cylinder. Consistent peaks indicate good mechanical health. A significant drop in a peak suggests a compression issue in that cylinder.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Autel MaxiSys Ultra:

• Software Updates: Regularly check for and install software updates via Wi-Fi to ensure the latest vehicle coverage, bug fixes, and new features.
• Cleaning: Keep the tablet and VCMI clean. Use a soft, damp cloth to wipe surfaces. Avoid abrasive cleaners or solvents.
• Screen Protection: Consider using a screen protector to prevent scratches and damage to the display.
• Storage: Store the device and its accessories in the provided carrying case in a dry, cool environment when not in use.
• Battery Care: Avoid fully discharging the battery frequently. Charge the tablet regularly, even when not in active use, to maintain battery health.

7. Troubleshooting

If you encounter issues with your Autel MaxiSys Ultra, consider the following troubleshooting steps:

• No Power: Ensure the tablet is fully charged. Check the power adapter and charging cable for damage.
• VCMI Connection Issues: Verify the VCMI is securely plugged into the vehicle's OBD-II port. Check the Wi-Fi connection between the VCMI and the tablet. Restart both the tablet and the VCMI.
• Software Freezing/Lagging: Close unnecessary applications running in the background. Perform a system restart. Ensure sufficient storage space on the tablet.
• Vehicle Communication Error: Confirm the vehicle's ignition is on. Check the vehicle's battery voltage. Ensure the correct vehicle make, model, and year are selected in the software. Verify the OBD-II port is functioning correctly.
• Inaccurate Readings: Ensure all test leads and clamps are correctly connected and calibrated (e.g., zeroing the current clamp). Check for any damage to the leads or sensors.
