THINKCAR Training Steps

Getting Started with Your ThinkTool

Step 1: Charge the device before use

Before powering on for the first time, charge your ThinkTool fully using the supplied charger. Do not use third-party chargers, THINKCAR states this can cause damage and voids warranty support. Battery capacities vary by model: the Lite 2 is 4000mAh, the Expert 195 is 12,600mAh, and the Max Plus is 9,300mAh.

Tip: If the tablet won’t turn on after extended storage, this is normal. Charge for at least 15 minutes before attempting to power on.

Step 2: Power on & Initial Setup

Press and hold the power button to switch on. On first boot, you will be guided through:

1. Language selection: Choose your preferred language from the available list.

2. Time zone: Select your time zone. The system will auto-configure the date and time.

3. Wi-Fi connection: Connect to a trusted Wi-Fi network. Wi-Fi is required for software downloads, updates, and online programming functions. If no network is available, a mobile phone hotspot can be used.

4. User agreement: Read and accept the terms and conditions, then tap Next to continue.

5. Account creation: Register with your email address. If you already have a THINKCAR account from another device, you can log in with your existing credentials.

Important: Wi-Fi must be set up before use. Without it, diagnostic software cannot be downloaded and online functions will not work.

Step 3: Activate your VCI (Vehicle Communication Interface)

Your ThinkTool communicates with the vehicle via a VCI (also called a ThinkDiag connector or diagnostic adapter). Before first use, the VCI must be activated:

1. Locate the VCI’s serial number, this is printed on the back of the VCI unit.

2. Locate the 8-digit activation code, this is on a white sticker inside the manual booklet supplied with your device.

3. In the tablet’s main menu, go to VCI Management, enter the serial number and activation code, and tap Activate.

Once activated, the VCI is bound to your account. Communication between tablet and VCI is via Bluetooth or Wi-Fi depending on the model.

Tip: Keep your activation code sticker safe. If you lose it, contact LaunchSA for assistance — +27 11 397 3072.

Step 4: Connect VCI to Vehicle

The OBD2 port (also called the DLC — Data Link Connector) is the physical connection point on the vehicle. On most passenger vehicles it is located under the dashboard on the driver’s side, above the foot area.

Common OBD2 port locations include:

• Under the dashboard left of the steering column
• Behind a small cover panel near the centre console
• In the footwell to the driver’s left

Plug the 16-pin end of the diagnostic cable into the vehicle’s OBD2 port. The device powers on automatically from the vehicle’s 9–36V supply. The indicator light will turn on when correctly connected.

If the vehicle’s DLC is not a standard OBD2 port, use the corresponding adapter from the adapter set included with your ThinkTool.

Important: Ensure the vehicle’s ignition is switched ON (engine does not need to be running) before beginning diagnosis. Some tests require the engine to be running, the tool will prompt you when this is needed.

Step 5: Run A full system health scan

After vehicle identification, tap Health Report or Auto Scan to run a full vehicle system scan. The tool will automatically scan all available electronic control modules including:

Engine (ECM) · Transmission (TCM) · ABS · SRS/Airbags · Body Control (BCM) · Immobiliser (IMMO) · Battery Management (BMS) · TPMS · Steering Angle (SAS) · Air Conditioning · and more

The scan generates a diagnostic health report showing each system’s status, any stored fault codes (DTCs), and whether the system passed or failed. This report can be saved and printed (if a printer module is attached) or shared digitally.

Diagnostic records are stored under the History menu and can be reviewed at any time.

Tip: Always run a full health scan first before diving into specific systems. It gives you a complete picture of the vehicle’s electronic state in one step.

Step 6: Identify The Vehicle

All ThinkTool tablet models support AutoVIN (Automatic Vehicle Identification). This reads the VIN directly from the vehicle’s ECU to automatically identify the make, model, and year, without manually navigating menus.

How to use AutoVIN:

1. On the main diagnostic screen, tap Intelligent Diagnosis or the AutoVIN button.
2. The tool connects to the VCI and reads the VIN from the vehicle ECU.
3. The VIN is matched against the server to retrieve vehicle information.
4. Confirm the details and tap OK to enter the diagnostic menu.

Manual VIN entry: If AutoVIN cannot read the VIN (e.g., some older vehicles), you can manually enter the VIN code or select the vehicle make, model, and year from the menu tree.

Tip: AutoVIN is the fastest way to start; it eliminates errors from manual vehicle selection and takes only a few seconds.

Core Functions

Key Diagnostic Functions Explained

What each major function does and when to use it. Availability varies by ThinkTool model; check the legend on each card.

Read Fault Codes (DTCs)

Reads all Diagnostic Trouble Codes stored in the vehicle’s ECUs. Shows the code number, description, and which system generated it. Always start here to understand what faults have been logged.

(ALL MODELS)

Clear Fault Codes

Erases stored DTCs from the ECU after the fault has been diagnosed and repaired. Clears the Check Engine / MIL warning light. Do not clear codes before recording them, cleared codes cannot be retrieved.

(ALL MODELS)

Live Data Stream

Displays real-time sensor data from the vehicle while it is running, including engine RPM, coolant temperature, fuel trims, O2 sensor readings, battery voltage, and hundreds of other parameters. Data can be graphed, compared, and saved for analysis.

(ALL MODELS)

Actuation Tests (Active Test)

Sends commands to individual vehicle components: injectors, relays, solenoids, fans, pumps, to test whether they respond correctly. Allows you to confirm a component works without running the engine or waiting for it to activate naturally. Saves significant diagnosis time.

(ALL MODELS)

Bi-Directional Control

An extension of actuation testing allows two-way communication with vehicle systems. You can command the vehicle’s ECU to activate or deactivate components and read back the response. Essential for confirming whether a fault is in the component itself or the control circuit.

(ALL MODELS)

ECU Coding & Adaptation

Programs the ECU to match replaced or new components (e.g., a new throttle body, injector, or module). Also used to enable or disable vehicle features and match sensor calibration values. Available for a wide range of makes including Benz, Ford, BMW, VW/Audi and more.

(EXPERT & MASTER RANGE)

Online Programming

Connects via Wi-Fi to the THINKCAR programming server to flash or reprogram ECUs and TCUs with the latest firmware. Required when replacing major control modules or resolving software-related vehicle faults. Requires a stable Wi-Fi connection during the entire process.

(MASTER & MAX RANGE)

Topology / CAN Bus Map

Displays a visual map of all the vehicle’s electronic modules and their communication status on the CAN Bus network. Green = communicating normally, Orange/Red = fault detected. Makes it immediately clear which modules are offline or reporting errors, cutting diagnosis time significantly.

(MASTER 2 & MAX PLUS)

Remote Diagnostics (TeamViewer)

Allows a certified remote expert to access your ThinkTool in real time via the internet. The expert can see your screen, operate functions, and guide you through complex jobs, ECU programming, key coding, and difficult fault diagnosis, without the vehicle leaving your workshop.

ADAS Calibration

Calibrates Advanced Driver Assistance Systems after windscreen replacement, suspension work, or sensor/camera replacement. Covers forward-facing cameras, radar sensors, ACC (Adaptive Cruise Control), LDW (Lane Departure Warning), blind spot sensors, and parking cameras, to OE-level accuracy.

(MASTER X PLUS, MASTER CV, MAX PLUS, EXPERT 399)

Freeze Frame Data

When a fault code is stored, the vehicle ECU also saves a snapshot of all sensor values at the exact moment the fault occurred. Freeze Frame lets you review these conditions, extremely useful for diagnosing intermittent faults that are not present when you connect the tool.

(ALL MODELS)

Diagnostic Reports

After a health scan, the ThinkTool generates a full diagnostic report showing all systems checked, fault codes found, and overall vehicle health status. Reports are saved in the History menu. If a printer module is attached, they can be printed on-site and handed to the customer.

(ALL MODELS)

Troubleshooting

Common Issues & Solutions

Based on official THINKCAR guidance. For issues not resolved here, contact the LaunchSA technical support team.

Try the following steps in order:

  1. Ensure the device has been charged using the supplied charger — not a third-party charger.
  2. If the battery has not been used for a long time or is fully depleted, charge for at least 15 minutes before attempting to power on. This is normal behaviour.
  3. Press and hold the power button for 5–8 seconds (not a quick press).
  4. If still unresponsive, contact LaunchSA technical support: +27 11 397 3072

A communication error means the tool cannot establish a connection with the vehicle’s ECU. Work through these checks:

  1. Check the OBD2 connector is fully seated in the vehicle’s DLC port — it should click into place.
  2. Check the ignition is switched ON (key in, engine does not need to be running).
  3. Check the VCI Bluetooth/Wi-Fi connection — go to VCI Management on the tablet and confirm the VCI is connected.
  4. Try a different vehicle to determine whether the issue is with the tool or the specific vehicle.
  5. If the vehicle is older (pre-1996), it may not support OBD2 protocols. Check vehicle compatibility before connecting.
  6. If using a non-standard DLC port, ensure the correct adapter from the adapter set is being used.

  1. Restart the device — press and hold the power button, select Restart.
  2. If the issue continues, check that the device’s software is fully up to date via the Update menu.
  3. If freezing occurs during a specific diagnostic function on a specific vehicle, use the in-app Feedback function to report it. THINKCAR’s engineering team reviews feedback and releases fixes through software updates.
  4. As a last resort, a factory reset can be performed via Settings. Note: this erases all stored diagnostic data and reports. Back up any important reports before proceeding.

  1. Check your Wi-Fi connection — a stable connection is required throughout the download. Move closer to the router if signal is weak, or use a mobile hotspot.
  2. Check available storage — if internal storage is full, updates cannot download. Delete unused vehicle brand software files to free space.
  3. Do not attempt updates with low battery — connect to the charger before downloading large update packages.
  4. If the download consistently fails for a specific vehicle brand, try downloading other brands first. Report persistent failures via the in-app Feedback function.

  1. If a vehicle make or model is not found in the software:
    1. Ensure your software is fully up to date — new vehicle coverage is added regularly via updates.
    2. Check the vehicle’s model year — OBD2 support is generally required (post-1996 petrol, post-2001 diesel for most makes).
    3. Some newer vehicle models may require a software update that adds coverage. Check the update menu after connecting to Wi-Fi.
    4. For specific vehicle coverage queries, contact the LaunchSA team who can confirm whether your target vehicle is supported on your specific ThinkTool model: +27 11 397 3072

Online programming requires a stable, uninterrupted Wi-Fi connection throughout the entire process. A failed programming session can leave a vehicle’s ECU in an incomplete state, treat this as critical.

  1. Before starting any online programming, confirm your Wi-Fi signal is strong and stable.
  2. Connect the tablet to the charger — do not attempt programming on battery alone.
  3. Ensure the vehicle battery voltage is sufficient. A low vehicle battery can interrupt programming. Use a battery support unit if available.
  4. Do not operate any other apps or functions on the tablet during programming.
  5. If programming fails or is interrupted, do not disconnect from the vehicle and do not switch off the ignition. Contact LaunchSA immediately for assistance: +27 11 397 3072
⚠️ Important: If your model supports Remote Diagnostics (Master X PLUS, Expert 399, Max Plus), you can request a certified remote expert to assist with complex programming jobs in real time via the Super Video Remote Diagnostics service.

  1. For physically installed modules (Printer, Battery Tester, Thermal Imager, WorkLight, Video Scope): check the aviation connector alignment. The red dot on the connector must align with the red dot on the socket before inserting. Never force the connection.
  2. For USB modules: ensure the USB cable is fully inserted at both ends. Try a different USB port if available.
  3. For Bluetooth modules: go to the module management section in the tablet’s settings and re-pair the module.
  4. Restart the tablet with the module connected — the system will re-detect it on boot.
  5. Confirm the module is compatible with your specific ThinkTool model. Not all modules work with all models — refer to the compatibility notes in the modules section above or contact LaunchSA.
