Multiecuscan app for iOS

Both Windows and iOS version have the same coverage and the same functionality. The iPhone/iPad version, however, is completely separate from the Multiecuscan for Windows and it is also more expensive. It can only be purchased from Apple’s App Store and it is not linked to the Windows’ version. The licensing is also different - it can be purchased only for a year and stops working after the period expires. Also, for the iPhone version you will need an iOS certified Bluetooth/BLE interface or a WiFi interface. The iPhone Multiecuscan app works only with CANtieCAR v4.x/v5.x WiFi, CANtieCAR v5.x BLE, ELM327 WiFi, OBDLink MX WiFi, OBDLink MX+ Bluetooth, Vgate vLinker BLE/WiFi. It does not work with other interfaces.
The iPad version of Multiecuscan also works on the newer MacBooks with M1/M2 chips. You can install it directly from the AppStore.

Configuration

The settings screen allows to set language, type of OBD interface, graph type and scale (for the Parameters view), units.
Currently the Multiecuscan App supports the following OBD interfaces:
- CANtieCAR v4.x/v5.x WiFi - The interface should be updated with recent firmware and switched to WiFi mode (from the SYSTEM.INI file which is in SYSTEM folder on the flash drive). The CANtieCAR should be plugged into OBD port of the car and the RADIO led on back of interface will blink in white to indicate that it works in WiFi mode. The iPhone/iPad/MacBook should be connected to CANtieCAR_WTCxxxx WiFi hotspot.
- CANtieCAR v5.x BLE Bluetooth - The interface should be updated with recent firmware and switched to Bluetooth mode (from the SYSTEM.INI file which is in SYSTEM folder on the flash drive). The CANtieCAR should be plugged into OBD port of the car and the RADIO led on back of interface will blink in blue to indicate that it works in Bluetooth mode. No further configuration required on the iPhone/iPad/MacBook.
- Vgate vLinker MS - No pairing/configuration required on the iPhone/iPad/MacBook.
- OBDLink or Vgate vLinker WiFi - The iPhone/iPad/MacBook should be connected to the WiFi hotspot of the OBD interface.
- OBDLink MX+ or Vgate vLinker FS Bluetooth - The iPhone/iPad/MacBook should be paired and connected to the Bluetooth device. This should be performed from the Settings app on the iPhone/iPad.
- Vgate vLinker BLE - No pairing/configuration required on the iPhone/iPad/MacBook.
- ELM327 WiFi - The iPhone/iPad/MacBook should be connected to the WiFi hotspot of the ELM327 interface.

It is recommended to leave the interface configuration as "Auto-detect"! The app will automatically detect the interface when you try to connect to a module or scan for modules. You can try to manually select interface type only if "Auto-detect" fails to work correct.

Please note that Multiecuscan App will needs permission to use WiFi and Bluetooth on the iOS device. It will ask for this permission the first time, but in case you have disallowed it by mistake then you can check this in the iPhone's Settings app:
Settings -> Privacy & Security -> Local Network -> Multiecuscan (turn ON).
Settings -> Privacy & Security -> Bluetooth -> Multiecuscan (turn ON).

The connection with WiFi interfaces may also be interrupted by the "Wi-Fi Assist" function on iPhones. This function usually does not cause problems, but you can try to turn it off if you have problems with the connection between iPhone and OBD adapter:
Settings -> Mobile Service (scroll to bottom) -> Wi-Fi Assist (try to turn OFF)

Scan vehicle/modules

Click the "Scan" button on main screen to perform full scan for modules and DTC codes in each module. The app will display the SCAN screen and will start the scanning process. The full scan usually takes a few minutes and the app will display the progress.
When scan is complete, and Multiecuscan has found error codes in one or more modules, it will display "Clear Errors" button. You can tap on this button to clear all error codes from all modules.

Connect to vehicle/modules

Here, you can select system type Engine, Brakes, Transmission, etc. Then Multiecuscan app will display a list of available control module models. You have to select a module from the list. Then tap "Connect" to begin the communication with selected module. Upon successful connection Multiecuscan will display the "Info" screen.
You can also tap "Simulate". This will start a demo connection with the module (it will display fake/test data, no actual connection to vehicle). You can use this to explore functionality without need for vehicle and OBD interfaces.
Here, it also possible to swipe left/right instead of tapping on Connect or Simulation buttons.

Info screen

Errors screen

This screen will display stored error codes from the connected module. The error codes are meant to help with identifying and fixing problems on the car. Some of the error codes may be displayed in red - this means that the fault is still present (still detected by the control module) and the error code will most probably re-appear right after clearing.
You can tap on "Clear errors" (top-right of screen) to clear all stored error codes from the module. Please note that these errors might re-appear if the actual problem, which caused them in the first place, is not fixed.
You can swipe left any of the error codes on screen and select "Details" to display additional information about the fault.

Parameters screen

This screen will display the live data parameters for the connected module.
