This Quick Start Guide helps you install, connect and use your AAC Module for the first time.
The guide is general and applies to the AAC Module and AAC Control app. Vehicle-specific installation steps are not included here. Please follow the installation video for your exact vehicle model on our YouTube channel.
For the latest list of supported vehicles, always check the product page.
1. What the AAC Module Does
The AAC Module helps you control selected driver assistance systems in your Toyota more easily.
Depending on your vehicle and configuration, the module can help with systems such as:
- Speed warning (ISA – Intelligent Speed Assistance)
- Lane Departure Alert (LDA) or Lane Tracing Assist (LTA)
- Pre-Collision System (PCS)
- Driver Monitoring System (DMS)
- Blind Spot Monitor (BSM) and Rear Cross Traffic Alert (RCTA)
- Parking Support Brake (PKSB) or parking warning systems
- other vehicle warnings or assistance functions
Instead of changing several settings manually after every start, you can use the AAC Module to apply your preferred setup more quickly.
Depending on your settings, this can be done manually with the Cancel button on the steering wheel or automatically with AutoPreset™.
2. Important Safety Notice
The AAC Module can automate the operation of certain vehicle systems. Depending on your settings, warnings or warning lights may not be shown as originally intended by the vehicle manufacturer.
You, as the driver, remain fully responsible for the vehicle, your passengers and all road users at all times.
Only use the AAC Module where it is legal to do so. Regulations may differ depending on your country or region.
Do not configure the app while driving. Stop the vehicle safely before changing settings.
After installation or configuration changes, test the module in a safe place before normal road use.
3. Before You Start
You need:
- the AAC Module with the corresponding wiring harness
- a smartphone with the AAC Control app installed
4. Install the Module
Before installation, make sure the vehicle is safely parked, secured against rolling, and completely switched off.
The AAC Module is installed inside the vehicle using the supplied plug-in harness.
The exact installation location and steps depend on the vehicle model. For this reason, this guide does not include vehicle-specific installation instructions.
Depending on the vehicle model, the installation can be carried out by yourself or by a qualified workshop.
Please follow the correct installation video for your vehicle on our YouTube channel.
After installation, continue with the app setup.
5. Install the AAC Control App
Download and install AAC Control from:
- Apple App Store for iPhone
- Google Play Store for Android
Open the app after installation.
On first launch, the app will show a usage notice. You must accept this notice to continue.
The app is used to connect to the module, select your vehicle, configure functions and install firmware updates.
6. Allow Required Permissions
AAC Control requires Bluetooth access to connect to the module.
On some devices, additional permissions such as location access may be required because the operating system uses these permissions for Bluetooth device scanning.
Allow the requested permissions when the app asks for them. Without these permissions, the app will not work properly and will not be able to find your module.
7. Connect to the Module
To avoid discharging the starter battery, it is recommended to start the engine or switch the vehicle to READY mode.
- Ensure that Bluetooth is enabled on your smartphone.
- Start the vehicle.
- Tap the module image or the connection status on the dashboard.
- Select AAC V2 when it appears.
- Wait until the app shows Connected.
8. First Setup
When the module is connected for the first time, the setup assistant starts automatically.
Select the correct vehicle model. Choosing the wrong model can lead to malfunctions.
Step 1: Select Your Vehicle
Choose your exact vehicle model from the list.
Only select systems that are actually available in your vehicle.
Step 2: Choose Your Settings
1. Select Systems
Choose which driver assistance systems the AAC Module should manage. Only select systems that are actually available in your vehicle. By default, no system is selected.
2. Warning Light Suppression
Decide whether warning lights for deactivated systems should be hidden (for example “PCS OFF”). This function is disabled by default and must be enabled manually if required.
3. Choose Activation Method
Select how the AAC Module is activated and deactivated:
- Standard: Hold the Cancel button for about 1 second to activate and about 2 seconds to deactivate.
(Enabled by default) - Multipress: Press the Cancel button three times to activate or deactivate the module.
4. Select Module Version
Choose the desired operating mode:
- Standard: Settings are applied manually using the Cancel button. (Enabled by default)
- AutoPreset: The settings selected in the app are automatically applied each time the vehicle is started. (
- Memory Mode: The settings configured directly in the vehicle settings are automatically applied again at the next start.
5. Deep Sleep
Define whether the module should enter Deep Sleep mode when the vehicle is switched off.
This function is enabled by default and helps protect the vehicle battery.
Tap Finish when setup is complete.
9. Activate the Module
Activate the AAC Module:
- Start the vehicle.
- Press and hold the Cancel button on the steering wheel for about 1 second (Standard Mode), or press it 3 times (Multi-Press Mode), depending on your selected setting.
- The module will activate and apply your configured settings.
After activation, the selected assistance systems will be deactivated.
Deactivate the AAC Module:
- Press and hold the Cancel button for about 2 seconds (Standard Mode), or press it 3 times again (Multi-Press Mode).
10. AutoPreset™
AutoPreset™ is an optional paid feature.
The settings selected in the app are automatically applied after each vehicle start.
This means you do not need to press the Cancel button manually after each start.
AutoPreset™ can be unlocked in the app by:
- in-app purchase
- activation code
One AutoPreset™ licence is linked to one module.
11. Memory Mode
Memory Mode is included with AutoPreset™.
Instead of using fixed app-selected settings, Memory Mode lets you adjust the settings directly in the vehicle. The vehicle’s current settings are saved when it is switched off and automatically restored at the next start.
In simple terms:
- You set the systems directly in the vehicle.
- The module saves your settings.
- After the next start, similar to AutoPreset™, the module automatically restores these settings.
14. Warning Light Suppression
If warning light suppression is active, certain warning lights are no longer shown while the module is active.
13. Firmware Updates
- do not switch on the ignition
- do not close the app
- do not lock the phone
- keep the phone close to the module
- do not disconnect the module
With the AAC Module V2, the module firmware can be updated wirelessly.
When an update is available, the app will show an update message on the dashboard.
To update:
- Connect to the module.
- Open the Information tab.
- Select the firmware update section.
- Download the update.
- Switch the vehicle off
- Start the installation.
- Keep the app open until the update is complete.
The update may take several minutes.
14. Deep Sleep Mode
The AAC Module monitors the vehicle’s battery voltage when the vehicle is switched off.
If the battery charge level becomes low, the module automatically switches itself off to help protect the battery from further discharge.
Switching on the vehicle will wake the module again.
Your settings remain saved.
15. Resetting the Module
AutoPreset™ and other purchased licences remain stored.
A reset deletes the selected vehicle model and configuration.
You may use the reset if...
- you selected the wrong vehicle model
- you want to install the module in a different vehicle
- you want to set up the module from the beginning
After a reset, the setup opens again and the module can be configured from the beginning.
16. Troubleshooting
The app does not find the module
Try the following:
- make sure the vehicle is switched on
- after 2 minutes bluetooth deactivates till the car is started again
- switch the vehicle off and on again
- restart the app
If the wrong vehicle model was selected during setup, the module may not detect when the vehicle is started and Bluetooth may not be activated.
In this case, restart the module by briefly disconnecting the vehicle’s starter battery.
The settings cannot be changed
The module is probably active.
Deactivate the module first using the Cancel button, then open the configuration again.
