Auto ISM

Auto ISM is a vehicle repair reference app that provides wiring diagrams, manuals, and DTC lookups.

Auto ISM fits workshop routines where fast access to information saves time at the bay. It gathers diagrams, service references, and code descriptions in one place, so you can move from a fault to a check without switching tools. Navigation starts with the vehicle brand and system, then narrows to the materials you need. Keeping the Auto ISM APK on your phone or tablet helps you pull up the right page during diagnosis.

Auto ISM Features

Wiring, schematic, and connection diagrams

You choose a brand and system, then open the drawing that shows harness paths and component connections. Pinch to zoom and drag to read small labels on a phone or tablet. Coverage can vary by model year, so compare related views when needed. Updates in the Auto ISM latest version may add clarifying notes or additional diagrams for newer vehicles.

Service and workshop manuals

Next, open manuals to review procedures, specs, and illustrations before starting a job. Use them to confirm torque values, sequences, and fluid quantities. To avoid mismatches, verify model year, engine code, and system variant, then compare key steps against the diagram you plan to test.

English DTC search

Enter a fault code to see the English description and repair oriented guidance. For example, a misfire code can prompt you to confirm ignition and injector signals, then trace the circuit on the related diagram. If the note feels broad, apply brand or system filters to tighten the context.

Vehicle system overviews

Read system overviews to understand structures and signal flows before picking test points. This context helps set an efficient order of checks and reduces unnecessary part removal. Use the overview to plan, then confirm findings with live data or measurements on the car.
