iOS Application, CAN Engine, and a new Kohler Bluetooth Diagnostic Interface Module

A Kohler Bluetooth Diagnostic Interface Module manufactured before February 2019 will have firmware that is not compatible with the iOS app connecting to a CAN engine.  There are a few ways to update the module so it will work.

• Disconnect the ECU on the CAN engine, so the module does not receive CAN data but is still powered by the engine.  When you attempt to read data, the iOS app should update the module.

• Connect the module via bluetooth to an Android device running the Kohler Android app. When you attempt to read data, the Android app should update the module.  After that it should work on iOS.

-or-

• Connect the module to a K-Line engine with a Delphi controller.  When you attempt to read data, the iOS app should update the module.
