Heavy Vehicle Fault Code Advisor APK

We regularly release updates to this app which include updated background data, new functions as well as improvements to speed and quality.

Heavy Vehicle Fault Code Advisor translates MID, CID, FMI, SPD and Event ID codes to assist in diagnosis.
If your piece of equipment displays fault codes, this tool may assist by interpreting those fault codes WITHOUT THE NEED FOR OTHER TOOLS such as Bluetooth data link adapters etc. All translations are even done offline!

Enter your codes in and select 'Translate' and instantly, the app will translate the codes based on publicly listed fault codes, even when offline.
For example, if you have MID 36, CID 1 and FMI of 5, it will be translated to Engine control 1, Injector number 1 and current below normal. This would indicate that there is a possible issue with injector number 1 or the wiring that goes to it, giving repair personnel somewhere to start with diagnosis.

This app is available only in English
